Statements of Former Philip Morris Employees
The following are the declarations to the Food and Drug Administration of three former tobacco industry employees that seemingly contradict the publicly held position of the industry on the purposes and nature of their own research into the effects of their products and the process of "restoring" nicotine to cigarette tobacco. The FDA is soliciting comment on these declarations.

[Docket No. 95N-0253J]
Analysis Regarding The Food and Drug Administration's
Jurisdiction Over Nicotine-Containing Cigarettes and Smokeless Tobacco Products; Reopening of the Comment Period as to Specific Documents
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice; reopening of comment period as to specific
documents.
SUMMARY: The Food and Drug Administration (FDA) is reopening
to (insert date 30 days after date of publication in the Federal
Register), as to specific documents, the comment period on its
analysis regarding FDA's jurisdiction over these products, which was
published in the Federal Register of August 11, 1995 (60 FR 41453).
FDA is reopening the comment period for 30 days for the sole
purpose of inviting public comments on the information being added
to the administrative record. Elsewhere in this issue of the Federal
Register, FDA is reopening the comment period, as to specific
documents, for its proposed rule entitled "Regulations Restricting the
Sale and Distribution of Cigarettes and Smokeless Tobacco Products
to Protect Children and Adolescents.
DATES: Written comments must be received or postmarked on or
before (insert date 30 days after date of publication in the Federal
Register). Comments postmarked after such date will not be
considered.
ADDRESSES: Submit written comments to the Dockets Management
Branch (HFA-305), Food and Drug Administration, rm. 1-23, 12420
Parklawn Dr., Rockville, MD 20857.

SUPPLEMENTARY INFORMATION: In the Federal Register of
August 11, 1995 (60 FR 41453), FDA published a notice containing
an analysis of FDA's jurisdiction over nicotine-containing cigarettes
and smokeless tobacco products. The analysis supported a finding at
that time that nicotine in cigarettes and smokeless tobacco products is a
drug and that these products are drug delivery devices within the
meaning of the Federal Food, Drug, and Cosmetic Act (21 U.S.C.
321-395).
In the Federal Register of October 16, 1995 (60 FR 53620), FDA
extended to January 2, 1996, the comment period on the notice that set
forth the jurisdictional analysis.
FDA is adding three statements from former industry scientists and
employees to the administrative record. These statements, describe
among other things, the industry's understanding of nicotine and
industry practice with respect to the control of nicotine levels in
cigarette manufacture.
FDA might rely on these statements in support of any final decision it
may make on its jurisdiction. The agency is therefore providing the
public an opportunity to comment on them.
FDA believes that 30 days to comment is ample in this case, as the
agency is specifically limiting its reopening of the comment period to
comments on the statements being added. Comments are invited, and
will be considered, only to the extent they are focused on the
information being newly added to the record and only to the extent the
comments regarding such information raise new issues not already
raised by the person submitting the comment.
The documents being added to the record are as follows:
1. Uydess, Ian L., Declaration of Ian L. Uydess, Ph.D., February 29, 1996.
2. Farone, William A., Ph.D., "The Manipulation and Control of Nicotine and Tar in the Design and Manufacture of Cigarettes: A Scientific Perspective," March 8, 1996.
3. Rivers, Jerome K., Declaration of Jerome K. Rivers, March 7, 1996.
As part of its ongoing investigation, the agency has compiled information that includes notes and transcripts of interviews with former industry scientists and employees. These notes and transcripts have been referenced in this proceeding (Federal Register of December 27, 1995 (60 FR 6698 1)), but have not been included in the public
docket because, among other reasons, they would likely disclose the identity of sources that furnished information to FDA on a confidential basis (60 FR 66981), they were obtained under assurances of confidentiality, and in some cases they contain trade secret or other confidential information. Among these documents are notes and
transcripts reflecting conversations with Dr. Uydess, Dr. Farone, and Mr. Rivers, whose statements are identified above. Since the agency may rely on these statements, the agency is making them available for public comment now. The agency will not rely on any notes or transcripts made by the agency reflecting conversations with any former industry scientists and employees.
Interested persons may, on or before (insert date 30 days after date
of publication in the Federal Register), submit to the Dockets
Management Branch (address above) written comments regarding the
documents listed above. Four copies of any comments are to be
submitted, except that individuals may submit one copy. Comments
are to be identified with the docket number found in brackets in the
heading of this document. Received comments may be seen in the
office above between 9 a.m. and 4 p.m., Monday through Friday.

DECLARATION OF IAN L. UYDESS. Ph.D.
29 February 1996
Preface: The following accounts are offered with the understanding
that they are 'to the best of my recollection' and relate to matters that
occurred during the period of December, 1977 through
September,1989 (some dates are approximate).
Ian L. Uydess, Ph.D., declares as follows:
1. Employment Summary: Since June, 1993 I have been employed by the Analytical Laboratory Division of Pharmaco International, Inc. (previously Pharmaco LSR, Inc.) as Manager of Training & Safety. My office is located at 2244 Dabney Road in Richmond, VA, where my duties include the development and delivery our division's various technical, orientation, supervisory and safety training programs. I also developed and co- administrate our lab's new Performance Assessment Program and support our new business development group on an as-needed basis. Prior to my employment at Pharmaco. I worked as a resource development consultant to a number of small businesses in the Richmond area. However, a majority of my professional career over the past 15+ years was spent in the employment of Philip Morris USA, Inc., at their R&D facility at Commerce Road in Richmond, VA. This occurred over two separate periods, the first being December. 1977 through September,1981, and
the second between (approx.) April, 1982 and September, 1989.
2. First Period of Employment at Philip Morris (1977 - 1981): From December, 1977 to August.1981, I was employed as a Research Scientist by Philip Morris USA in their Richmond-based, Research & Development (R&D) department under Dr. William Farone (Division Director). I was promoted to Associate Senior Scientist near the end of
that period (spring of 1981?) as a result of my research in tobacco microstructure which attempted to correlate certain aspects of tobacco leaf structure to some of its chemical, physical and mechanical properties prior to, and after a number of the processing steps in the manufacture of a cigarette. This included scientific investigations of:
(1) native ('green') tobacco leaf, (2) flue and air-cured leaf, (3) 'expanded' leaf, and occasionally (4) reconstituted leaf ('RL'; discussed in greater detail in Section 5 page 4). To accomplish this, I frequently collaborated with the staff of other departments within
Philip Morris (such as Product Development, Manufacturing,
Engineering, Park 500, the Leaf Department and the Analytical Research Division) in order to support my studies on the impact of various processing conditions on the structure and chemistry of tobacco.
However, while I found my early employment at Philip Morris to be generally rewarding, I decided to leave that company in September, 1981 (of my own volition) to accept what seemed like a challenging management opportunity at Carl Zeiss-USA, Inc., in New York (as Product Manager for their Electron Optics Department in the US). Prior to resigning, I discussed the prospect of my leaving with
some of the people with whom I had developed a close relationship over the years (so as to get their input and recommendations regarding this offer). They included: Dr. Frank Gullotta, Mr. Cliff Lilly, Dr. William Farone and Dr. Thomas Osdene. Each expressed regret that I was thinking of leaving, but wished me well and added that they were
confident that I would be welcomed back to Philip Morris should my situation in NY not meet my expectations. In a very thoughtful gesture, Dr. Osdene took me out to an extended lunch at his private club (the Commonwealth Club) during my last week at PM.
While working at Carl Zeiss, I continued to maintain contact with
many of my Philip Morris coworkers and supervisors as a result of
the friendships that had developed during my employment with that
company. This included frequent visits with Dr. & Mrs. Frank
Gullotta, as well as occasional social gatherings with some of my
previous management.
3. Second Period of Employment at Philip Morris (1982 - 1989): I
decided to return to Philip Morris in the spring of 1982 as a result of a
number of contributing factors that included: (1) my family's mixed
feelings about relocating to New York, as well as (2) my own
(growing) disappointment with some of the aspects of my new job
with Carl Zeiss. My decision to return to Philip Morris early in the
spring of 1982 was made with the mutual agreement and support of
Dr. Jerry Whidby (Department Manager), Dr. William Farone
(Division Director) and Mr. Cliff Lilly (Principal Scientist). I returned
to Philip Morris at the same technical level at which I left (Associate
Senior Scientist) and remained there until September,1989, at which
point I resigned as a result of: (1) my great disappointment
(disillusionment) with the course (direction) of that company, and (2)
my growing professional and moral concerns regarding a variety of
smoking and health issues which had troubled me deeply for a great
many years.
4. Educational Background: I received my Bachelor of Science (BS)
degree with a major in Pre-Med./Biology from Fairleigh Dickinson
University, Madison, NJ in June, 1968. Subsequent to that (summer
of 1971 ?), I received a Masters of Science (MS) Degree at the
Roswell Park Division of the State University of New York at
Buffalo, followed in 1975 by a Ph.D. in Biology (major: Cell
Biology/Microbiology) from the Graduate School at the University of
Rochester, Rochester, NY. I actually began my post-doctoral work on
a project sponsored by the National Aeronautics & Space
Administration while I was preparing my thesis. Once this was
completed, I transferred from the Graduate School at the University of
Rochester to the University Medical Center (Strong Memorial
Hospital) as a Postdoctoral Fellow in Medicine to work in the area of
immunology and infectious disease (fall, 1975 - December,1977) . I
subsequently left Rochester in December, 1977 to accept a position at
Philip Morris
5. I first began working at Philip Morris after being recruited by Dr.
William Farone, Director of Basic Research. I was originally hired by
Philip Morris to work in the field of plant structural analysis and
biochemistry, with the hope that the information generated would
contribute to the development of new and/or improved products and
processes. In pursuit of this, I worked in the Microstructure Analysis
Lab where I investigated the relationship between: (1) the structure
and organization of native ('field') tobacco leaves, and (2) some of the
mechanical properties of processed leaves (such as after 'curing' and
'expansion'). In addition to this, I was later asked to support one of
the company's early attempts to investigate the usefulness of
bioengineering as a route to new and/or improved products and
processes under the umbrella of the company's 'lowered biological
activity' program.
This early biotechnology effort, the Naturally-Occurring
Denitrification Program ("NOD"), attempted to employ selected
bacteria to remove nitrate from SEL. 'SEL' (Strong Extract Liquor), is
the hot water extract of tobacco that is used to make one of Philip
Morris' reconstituted leaf ('RL') products at that company's Park 500
facility in Hopewell, VA. These reconstituted leaf materials (also
known as 'sheet' and 'recon') become one of the blend constituents in
many (if not all) cigarettes. A great variety of materials are present in
SEL which, depending upon the tobaccos used in this process, can
frequently contain a substantial amount of nitrate. The problem with
nitrate is that it can be degraded (converted) to nitrite, an
acknowledged, biologically-active material that once in cigarettes,
could pose a potential health hazard to smokers. Over the years (mid
1970s on), Philip Morris scientists attempted to remove this nitrate by
a variety of other technologies, but were not satisfied with the results.
My initial function during the early stages of this denitrification
(lowered biological activity) program, was as an internal consultant in
microbiology.
It was shortly after this that I decided to leave Philip Morris to accept
the position that had been offered to me at Carl Zeiss-USA in New
York (Sept.,1981). However, as mentioned earlier, I returned to
Philip Morris in the spring of 1982 to resume my research with that company.
A short time after returning to Philip Morris (early/mid-19837), I was
asked to take charge of the microbial denitrification program ("NOD")
which had continued during my absence under the leadership of a
variety of individuals, including: Dr. Vedpal Malik, Dr. Peter Kussel
and Mr. Joseph Banyasz. Drs. Malik and Kussel had both been hired
by Philip Morris expressly for this program. Mr. Banyasz, on the
other hand, had already been employed by Philip Morris for a number
of years and was an associate of Mr. Lilly who, as Principal Scientist,
helped to coordinate/manage this and other high priority/new
technology projects of the Company. The request that I take over
leadership of this project was communicated to me by my manager,
Dr. Jerry Whidby, with the input/support of the Division Director, Dr.
William Farone and Mr. Cliff Lilly (Principal Scientist). The technical
goal of this project (to denitrify the SEL from Park 500 by microbial
means) was successfully demonstrated soon thereafter (1983-1984),
although this technology was never used by Philip Morris in the
production of any of its products, allegedly for 'subjective' ('flavor')
reasons.
Virtually all of my duties from that time forth focused on work
related to product improvement issues.
6. My knowledge of the research conducted by Philip Morris during
the period Dec., 1977 through Sept., 1989 is the result of a number of
factors including: (1) my own, direct participation in a variety of
research and development projects conducted by Philip Morris during
this period. (2) my personal observations of activities in other parts of
the company over the 10+ years that I was employed by that
company, (3) my attendance at meetings and/or discussions held
between the scientists, engineers and management at Philip Morris,
and (4) my close association and friendship with a number of
scientists and senior management personnel over the many years that I was there.
Dr. Victor DeNoble and I were peers who discussed his work on a number of occasions. This was facilitated by the fact that we worked
in adjacent labs on the 3rd floor of the R&D building, as well as by
our growing friendship during this period.
At one point, we even discussed the possibility our collaborating on
a project that I had suggested to Dr. Thomas Osdene, the Director of
Dr. Noble's division. Dr. Osdene was enthusiastic about a research
proposal that I had written which recommended that we conduct 'in
vitro' studies using the white cells (lymphocytes and
macrophage/monocytes) from the blood of some of Dr. DeNoble's
experimental animals. The studies that were proposed were designed
to evaluate the effect of various smoke constituents such as Nicotine,
CO2, 'tars', etc., on the functionality (immunocompetence) of these
cells in culture. This proposal was an outgrowth of my work at the
University of Rochester Medical Center, and was based upon my
belief that it might provide Philip Morris with some positive data
regarding smoking and health (since these cells sometimes become
more 'competent' as a result of long-term, low dose exposure to
foreign materials/irritants dissolved in the blood). Dr. Osdene,
apparently excited by this prospect, went so far as to advocate that I
transfer into his division so as to facilitate these and other (related)
studies which he believed were better suited to his area of experience
and responsibility. He also suggested that these studies could be
conducted in Germany at INBIFO (a Philip Morris supported research
facility) if they proved to be 'too sensitive' to conduct in Richmond.
This option was apparently brought up in light of the company's
awareness and growing concern over the increased scrutiny of the
tobacco industry by the government (FDA) and public regarding
smoking and health issues. I was told that my participation in these
plans was incorporated into Dr. Osdene's proposal to expand the
animal behavior facilities of Dr. DeNoble. It was my understanding
that this proposal was being prepared for submission to the VP of
R&D in Richmond (Dr. Seligman), as well as to the appropriate
management personnel in NY. However, apparently unhappy with
this arrangement, Dr. Farone petitioned Dr. Seligman to keep me
within his division. This disappointed me and was one of the reasons
that I decided to leave Philip Morris in September 1981.
Dr. Frank Gullotta and I were not only colleagues at Philip Morris
but also, close personal friends (and, at least as of the time of this
writing, we still are). Dr. Gullotta and I discussed our respective work
on a regular (almost daily) basis throughout my employment with
Philip Morris (usually over coffee at informal, early morning meetings
in his office). During these discussions, Dr. Gullotta informed me of
the general results/observations of his research and was especially
excited to tell me about any new additions or modifications that were
made to his instrumentation (a computer-based 'olfactometer'/EEG).
During this time I also developed a close, professional relationship
with Dr. Thomas Osdene, the director of the Applied Research
Division. Dr. Osdene occasionally shared information with me which
(I assume) he thought would give me a broader understanding of the
inner workings of the company. In pursuit of this, he sometimes
exposed me to information that I probably would not have known
about from my own position within Philip Morris. Some of this
information regarded research that was being conducted within Philip
Morris, while on other occasions it was related to work that was being
contracted out to 'external partners' in the US and Europe (like INBIFO).
Dr. William Farone was the director who first brought me into Philip Morris. I reported directly to Dr. Farone during my early employment with that company and later, to a number of different departmental managers under him. Over the next few years, Dr. Farone and I developed a relationship (friendship, mutual respect) that extended
outside of our work at Philip Morris. In his attempt to support my development, Dr. Farone shared with me various aspects of his experiences and understanding of the company.
Mr. A. Clifford ('Cliff') Lilly (now Dr. Lilly) was a Principal
Scientist & 'Fellow' at Philip Morris whose charge it was to help
manage/guide projects of special import to the company (particularly
with regard to large, corporate initiatives involving new processes or
technologies). Mr. Lilly was at least informally associated with most,
if not all, of the projects that I participated in over a majority of my
years at Philip Morris (particularly between 1982 and 1989). Initially,
this was a result of my involvement with the Naturally- Occurring
Denitrification Program ('NOD') which he helped to oversee. Like Dr.
Farone, Mr. Lilly frequently mentored me in a variety of topics related
to the various efforts and/or undertakings of Philip Morris and shared
with me much of his knowledge and experience with the company.
7. To the best of my knowledge, Nicotine has always been an
important consideration to Philip Morris in the design, development
and manufacturing of cigarettes. Nicotine levels were routinely
targeted and adjusted by Philip Morris in its various products at least
in part, through blend changes and blend design. It is important to
note, however, that there are two nicotine levels that can be targeted
(and manipulated) in a cigarette: The first is the amount of nicotine that
is resident in the various leaf components that are used in the blend
(tobacco cultivars, stalk positions, amount of RL, etc.). The second is
the 'deliverable' nicotine that is found in the smoke (which, while
related to the chemistry of the tobaccos used, is modified by the
mechanical/burn characteristics of the cigarette). Both of these sources
must be (and were) considered by Philip Morris' development
scientists when formulating a new or modified product.
Whenever nicotine, or any other major component (such as sugars,
tars. etc.) had to be adjusted by Philip Morris in a new or existing
product, it was frequently a matter of knowing which tobaccos to use
in the blend to make the necessary (targeted) adjustments. This would
include the selection of various tobacco parameters such as: (a) the
mixture of cultivars used, (b) crop years and growth regions of each
and (c) relative stalk position and ripeness ('grade') of the tobaccos
that were selected. The amount and type of reconstituted leaf ('RL',
'BL', etc.) could also be used to contribute to the character (flavor,
'impact', etc.) of the final product. Adjustments such as these were
sometimes made as minor corrections to maintain the overall quality of
an existing product like Marlboro (which had to be manufactured year
after year without significant 'change'), while on other occasions,
they were employed in the design of a new product so as to meet the
targeted 'subjectives' (flavor and 'impact') of the new blend.
8. I have always believed that one of Philip Morris' key, corporate advantages is its detailed knowledge of tobacco chemistry. Over the years, Philip Morris scientists compiled a tremendous amount of information about the chemical composition, moisture levels and mechanical properties of a wide variety of tobaccos from various
regions around the world. This included trips made by a variety of the company's research and/or management personnel (or agents) to tobacco growing regions throughout the world.
In support of this, Philip Morris maintained an extensive database containing information about the various chemical, mechanical and agronomic properties of the tobaccos that it used in its products. Philip Morris scientists even investigated the changes that took place in hogs heads while the company's tobaccos where being held in inventory in their warehouses. These investigations included an analysis of how the environmental conditions of the warehouses (temperature, relative humidity, microbial loading, presence or absence of preservatives, etc.) affected this tobacco 'aging' process. A special curing chamber was even built within R&D so that Philip Morris scientists (such as Dr. Daniel Teng) could conduct experiments in which different aspects of the flue curing process could be evaluated under carefully controlled and monitored conditions.
In a separate but related effort. Philip Morris routinely investigated the chemical, physical, material and mechanical characteristics of its competitor's products so at to keep itself informed (on a continuing basis) of any 'changes' that might occur in these products as a result
of: (1) the use of new or modified processes and/or technologies, (2) the use of new or modified materials (papers, filters, etc.), and (3) any changes in the blend composition of those products which Philip Morris might interpret as a competitive advantage in the marketplace.
This effort was the responsibility of the 'CI' (Cigarette Investigations) Lab at Philip Morris.
9. When Philip Morris designed a new or modified blend, they used their stored tobacco inventories much like a scientist would use a chemical stockroom to select the ingredients needed to synthesize a new material. Whenever a new cigarette was being designed at Philip Morris, product development scientists would work in collaboration with the appropriate leaf department, manufacturing and R&D personnel to map out the targeted flavor and delivery (tar/nicotine) parameters of the new product. Key individuals in the flavor group (such as Howard Spielberg) were also consulted since new or modified flavor systems ('aftercuts', 'casings', etc.) would typically have to be developed to help deliver both the taste desired by the
smoker, as well as the mechanical (moisture) characteristics required by manufacturing. This latter consideration was important, since it allowed Philip Morris to control (within limits), the physical/mechanical properties of its tobaccos (and tobacco shreds) which helped assure that its blends would 'survive' the manufacturing process without too many problems (such as: inconsistent or poor cutting/shredding, over-drying, and excessive breakage during expansion or in the 'makers'; etc.).
10. To the best of my knowledge, Philip Morris routinely applied
this knowledge of selective tobacco blending to achieve desired
nicotine (as well as other, constituent) levels in the products that it
designed and marketed. On some occasions, Philip Morris researchers
submitted more than one version of the same experimental product to a
test panel or test market. This was done to study the market's potential
reaction to variations in the level of a targeted cigarette component
such as tars, sugars, flavor ingredients and nicotine. In the case of
nicotine, specific levels of nicotine would be targeted in the test
products (test 'articles') in a range that extended from 'ultra-low' (or
even zero) nicotine deliveries, to deliveries equal to, or slightly above
that found in some of their own (or a competitor's) 'full-flavor' or
'full-bodied' products. This was done to examine how the smoker
would react to various nicotine levels as a predictor of how well these
products might do in the market with specific regard to: "not enough
nicotine", "an acceptable level of nicotine", or"too much nicotine"
(etc.). The concentrations of nicotine (and/or tar) that were used
would span a range from ultra-low or zero levels (at which point the
product was sometimes rejected as being nothing more than a 'hot air
delivery device'), to test articles that had a somewhat higher level of
nicotine (which had a better chance of being 'liked' by the smoker). A
number of experiments were conducted in this area prior to, and
during my employment at Philip Morris.
11. Philip Morris scientists (development personnel and
management) understood the relationship between nicotine level and
product acceptability as a result of their long history of research and
experience in this area. As a result, it would come as no surprise to
anyone having experience in the product development area, that a
cigarette having satisfactory ('high enough') nicotine levels but
marginal flavor, stood a better chance of being 'accepted' in the
market place than a somewhat better tasting product with zero or ultra-
low levels of nicotine ('not enough'). This belief, that a cause-and-
effect relationship existed between cigarette acceptance and nicotine
delivery level, was reflected in many of the comments made at a
number of internal meetings at which zero and 'ultra-low' delivery
products were being discussed. Some scientists (like Dr. Gullotta)
even predicted that products made with 'no' or 'too low' a level of
nicotine would (probably) fail in test markets 'no matter what they
tasted like!' (e.g., that even smokers who were first attracted to the
'taste' of a new zero or ultra-low delivery product, would probably
abandon it after they 'sensed' that there was insufficient reinforcement
for them to continue to smoke it).
12. 'Impact' was the term generally used by Philip Morris
researchers to describe the (physiologic) effect that nicotine had upon
a person when they smoked a conventional, nicotine containing
cigarette. It was my understanding that smokers have told Philip
Morris (via test panels, etc.) that there is "no impact" in a cigarette that
lacks nicotine. The term 'impact' is used by the tobacco industry to
generally describe two separate effects. The first is the feeling that the
smoker experiences at in the back of the throat immediately upon
inhaling a nicotine-containing cigarette. The second is a somewhat
more complicated (and delayed) physiological effect which apparently
results from the interaction of nicotine with receptor sites in the brain.
'Flavor' (how the smoke 'tastes') and 'impact' (how the smoker
'feels') are two of the most important parameters of cigarette
acceptance by the smoker (in addition to smell, firmness, ease of
draw, burn characteristics, etc.). However, while both parameters are
important to the ultimate acceptability of a product, 'impact' (nicotine
delivery) was known to be the more powerful determinant in many of
these cases (in the long term, smokers would be more likely to stay
with a marginally-tasting product with adequate 'impact', while they
would tend to abandon one of relatively good flavor having no or
insufficient 'impact'). Philip Morris knew that the 'best' products
were obviously those that could deliver the proper amount of both of
these factors, 'flavor' and 'impact' (all other factors such as
'firmness' and 'draw', etc., being held constant).
13. I remember one meeting at Philip Morris at which the initial
results from the test market of a low delivery (ultra-low nicotine)
product were being discussed. The initial sales of the product in the
test market were reported to be fairly good, but shortly thereafter,
sales suddenly fell off. Apparently, while the test market smokers
thought that it tasted' O.K., they ultimately switched back to their
original brand because the new product was 'missing something'
(phrases like 'not satisfied' and 'lacks impact' were also used to
describe the smoker's response to this new product). It was suggested
that the product development group might have to adjust the blend so
as to raise the nicotine level in order to increase its 'staying power'
(acceptability and sales) in the market place. Tar, as well as tar-to-
nicotine ratios were also discussed. A rather ;energetic' discussion
followed in which the original blend parameters of the test product
(low tar/low nicotine) were discussed in light of the rather
disappointing, results that were obtained.
14. 1 once saw a graph during an informal discussion at Philip
Morris that generally correlated nicotine level to product acceptability.
The graph depicted this relationship between nicotine level and
product acceptability over a fairly wide range of nicotine levels from 0
mgs. to those commonly found a variety of products on the market at
that time (including some Philip Morris products as well as some
competitor's brands as reference points in the low- to high- nicotine
delivery range). Two lines had been hand-drawn, horizontally, across
the graph as 'high' and 'low' limits to indicate, at least in a general
manner, the range of nicotine levels over which adequate product
acceptability (market share) was believed to occur. The discussion at
that time centered around the prospect that there was, in fact, some
minimally-acceptable level of nicotine below which product
acceptability would be severely in question. Other comments had to do
with whether or not the company should even venture below this level
given the problems that were known to occur. It was my
understanding at the time! that these concerns were based upon the
results from test panels and/or test markets in which very low delivery
nicotine products had previously been evaluated. Some participants at
this meeting forwarded the idea that the flavor group could overcome
these 'problems', while others held fast to their belief that the data 'spoke for themselves'.
15. Tobacco companies like Philip Morris learned a long time ago,
that it was hard to get people to stay with a good tasting product if the
nicotine level was too low. It is fairly safe to say, that while taste is a
very important component of a smokers experience ('satisfaction')
with a cigarette, that good taste alone does not sustain a market Philip
Morris clearly understood this relationship between nicotine level and
product acceptability (e.g., that they could develop a market for a
medium to high nicotine product that had marginal taste, but that they
would have trouble sustaining the sales of a good- tasting product that
was too low in nicotine).
The information gained by Philip Morris from the chemical analysis
of tobaccos of different varieties, ripeness, (etc.), was used in the
blend design of new products to ensure that the desired amount of
'high' or 'low' nicotine tobaccos were present in order to deliver the
amount of nicotine (or other tobacco constituents) that had been
targeted for that product. It was my impression that Philip Morris
researchers and product developers knew, that if the nicotine level in a
cigarette fell too far below this lower limit, that they would have great
difficulty establishing a viable, long-term market for that product. This
knowledge about the optimum range for nicotine in a cigarette was
developed as a result of a great many years of investigation at Philip
Morris and could (generally) be reproduced by graphing the nicotine
levels of different brands of cigarettes (from 'high' to 'ultra-low')
against the market share that they each held.
16. Tobacco leaf chemistry (in particular, alkaloid/nicotine
chemistry) was exhaustively studied by Philip Morris. Philip Morris
wanted to know everything there was to know about nicotine,
particularly with regard to: (1) How nicotine levels varied in the
tobacco plant with regard to cultivar, stalk position, seasonal
variations and 'ripeness', (2) What happened to nicotine after curing'
and during processing, (3) What chemical 'forms' was it in, and (4)
How much of it wound up in the smoke when burned under different
conditions (such as in the presence or lack of oxygen, at different
temperatures, in the presence of varying amounts of other tobacco
constituents, etc.). A substantial amount (and variation) of equipment
was purchased by Philip Morris to study these topics, including:
liquid and gas chromatographs (HPLCs & GCs), mass spectrometers,
infra-red (FT-IR) spectrometers, nuclear magnetic resonance
instruments (NMRs), etc. In addition, Philip Morris researchers were
frequently sent out to acquire new skills (at classes, universities or
workshops) to support their investigations of these and other topics.
On several occasions, Philip Morris scientists helped advance the
state-of-the-art of some of these technologies by
discovering/developing new or improved ways of using their
equipment to study tobacco. Few people outside of Philip Morris truly
understood the extent and depth of Philip Morris' knowledge and
expertise in chemistry, biology and engineering (manufacturing).
Philip Morris routinely used its knowledge of tobacco chemistry in the
design and manufacturing of its products.
I always considered this lack of public knowledge about the true capabilities of Philip Morris to be one of that company's greatest corporate advantages.
17. In the 1980's, Philip Morris conducted field experiments on the growth of tobacco with elevated nicotine levels for possible use in their products. Philip Morris examined a technique called 'ratooning' which involved cutting down of the tobacco plant early in the harvest
cycle before the plant had fully matured. As the cut plant resumed its
growth, the roots deposited elevated levels of nicotine in the leaves of
the plant. The 'ratooned' plant was allowed to grow for a while and
was then harvested. This technique produced tobacco leaves that had
higher nicotine levels than the leaves of non-ratooned plants. I do not
know if any of the nicotine-rich leaves that were produced through
ratooning ever got into production, but it is my understanding that a
number of these studies were conducted by Philip Morris in the US
and possibly, overseas as well (under the guidance of Dr. Daniel Teng).
18. Philip Morris conducted experiments in which nicotine was produced in tissue culture. During the mid to late 1970's. Philip
Morris scientists set up a laboratory to investigate the production of
nicotine and other substances (such as mint) in tobacco cell and tissue
cultures. An outside investigator, Dr. Don Dougall was brought in as
a consultant to help support these investigations. Dr. Dougall, an
acknowledged expert in this field, made frequent trips to Richmond to
consult on this topic with Mr. Lou Weissbecker, Project Leader of this
group (Project 1730). Dr. Dougall was also contracted to conduct
similar (parallel) investigations in his own laboratory at the University
of Kentucky. A variety of cultural techniques (including variations in
growth conditions, nutrients, plant hormones, etc.) were evaluated in
each laboratory in an attempt to maximize the production of the
targeted materials. Samples of these cultures were periodically
analyzed to determine the level of nicotine (or other targeted
substance) that had been obtained. The overall goal of these studies
was to: (1) optimize the production of the targeted materials (such as
nicotine) in culture, (2) isolate the cells/tissues that demonstrated
elevated levels of production, and then (3) regenerate plants
('plantlets') from these tissues to see if the desired characteristic
would be expressed (maintained) in the regenerated plant. While
Philip Morris explored the potential (future) use of this and related
technologies, they did not at that time employ it in the manufacture of
any of their products. A similar group of programs was later
contracted out to Dr. Peter Carlson of Crop Genetics International in a
joint venture with Philip Morris to explore the application of plant
tissue culture and cloning techniques to the selection/regeneration of
tobacco plants with 'most desirable' characteristics (characteristics
selected/targeted by Philip Morris).
19. Understanding the chemistry of tobacco alkaloids was very
important to Philip Morris and was investigated by their scientists in a
variety of manners. Some of these scientists, like Dr. Jeff Seeman,
were skilled synthetic chemists who helped prepare a variety of
nicotine analogues for investigation by other researchers at Philip
Morris. This was done to examine how slight variations in nicotine
structure might impact its chemical, biological and behavioral
properties. The analogues that were prepared were provided to
scientists like Victor DeNoble for evaluation. Dr. DeNoble and his
coworkers examined these materials in a well known, animal behavior
system to see if they could identify a nicotine relative that had the same
habituating effect as nicotine without nicotine's reported negative
effect upon the cardiovascular system.
20. Doctor DeNoble's research on nicotine analogues was premised
upon the reported, habituating effect of nicotine. While Dr. DeNoble
and I frequently used this term when discussing the results and
observations of his experiments, there was a growing
concern/sensitivity among Philip Morris management regarding the
propriety of use of this and related terms (such as 'addictive') even
when used within the company. As time went on, memos, notebooks,
external communications and internal reports were increasingly
scrutinized (revised/censored) by Philip Morris management to make
sure that no 'sensitive' terms were being incorporated into any of the
company's written documentation.
21. The tobacco companies' response to allegations that nicotine was
'addictive' was to reply that nicotine was not addictive, because
nicotine did not cause the physiological responses necessary to meet
the classic definition of addiction. While this may be the position taken
by the management of Philip Morris, a number of scientists like
myself believed differently. We believed that nicotine was the critical
component of tobacco that compelled (motivated) people to smoke.
Our views on this topic were shared by a wide variety of individuals
within Philip Morris, although many people were very guarded about
who they would speak freely around. I always found it difficult to
understand Philip Morris' rigid position on this topic, particularly in
light of their obvious support of the rather unique research that they
were conducting in animal and human behavior. One explanation
commonly given by Philip Morris was, that this research was
'defensive' in nature and being done solely to inform the company
about the methods being used by antagonists/enemies of the tobacco
industry (in an effort to protect Philip Morris against potentially
adverse information developed by researchers external to the
company). However. if this was true and the only reason for this
work, why were some of these programs so long-term and extensive
in nature? In fact, instead of being short-term efforts conducted to
gather preliminary information on the kinds of results that may be
obtained by these technologies, these projects were expanded and
supported with additional resources as if they were indeed, formal,
long-term research initiatives of the company.
22. The public position of Philip Morris that nicotine was not addictive was possibly contradicted by the electrophysiology research that was conducted by Dr. Frank Gullotta. One of Philip Morris' greatest frustrations was it's inability to fully understand and use the
subjective information it received about a smoker's reaction to a cigarette (regarding its 'feel', 'flavor', 'impact', etc.). This is because a smoker's response to a new or existing cigarette product has been based, historically, upon information obtained from personal
interviews and written questionnaires, both of which suffer from the
very same problem: the imprecise nature of the words that we use to
express our thoughts and experiences. This made it difficult for Philip
Morris researchers to really understand all of the reasons why a
smoker 'liked' or 'didn't like' the brands that they tried, as well as
how it (Philip Morris) could use this information to formulate new
products.
Because of this, Philip Morris researchers wanted to find a way to
become less dependent upon these necessary, but imprecise subjective
results. To do this, they wanted to come up with a method to generate
'objective' (physical) data that they could: (1) understand more easily,
and (2) use more reliably to help formulate new products (hopefully,
through some kind of scientific measurement). This is where Dr.
Gullotta's electrophysiology work came in.
Dr. Gullotta is a Philip Morris scientist (Ph.D. in Experimental
Psychology) who worked closely with a variety of Philip Morris
engineers, flavor chemists and development personnel to design and
build a specialized aerosol delivery system, the 'olfactometer'. This
instrument was used in conjunction with an electroencephalograph
(EEG) to conduct experiments on human subjects using a variety of
test materials such as nicotine. Dr. Gullotta also worked closely with
Dr. Gehrt Kobol, a German researcher and recognized expert in this
field, who was hired by Philip Morris as an external partner and
consultant. Drs. Gullotta and Kobol communicated regularly (via
phone and mail) and visited one another on a number of occasions.
Substantial, technical upgrades were made to Dr. Gullotta's equipment
(olfactometer, computer and EEG) on a number of occasions to
increase its capabilities for use in these studies.
Cigarette smoke, or a specially formulated aerosol containing
nicotine or some other cigarette component (such as a flavorant,
carbon dioxide, or a mixture of materials), was administered to a
subject (usually a volunteer from the PM staff) under highly
controlled, experimental conditions. The smoke or aerosol was
introduced into the mouth or nose of the subject in precise amounts
using the sophisticated metering system (of reservoirs, valves, etc.) of
the olfactometer. The olfactometer, in turn, was integrated with a
state-of- the-art EEG and a computer. The relationship between a
variety of chemical substances and the brain's electrochemical
response to those materials (as measured by EEG) had already been
'mapped' and reported in the literature for a number of substances
including nicotine. These data, methods and observations were used
as the basis for the studies that were conducted at Philip Morris.
Dr. Gullotta's initial investigations were conducted to verify the
effectiveness and utility of this approach. However, they soon
graduated to sophisticated experiments designed to evaluate (and
hopefully, establish) a correlation between the structure/chemistry of
the chemical agent to which the subject was exposed, and: (1) the
effect that this chemical had on the subject's ability to perform a task
during (and just after) their exposure to the agent, and (2) changes in
the electrical activity (EEG pattern) that occurred in the brain while this
was being done. The 'task' usually involved the subject's response to
an auditory or visual stimulus (such as changing patterns on a TV
monitor). The subject's own interpretation of their experiences was
also evaluated in some of these studies in an attempt to correlate the
subjective data to the EEG patterns that were observed.
The responses monitored by Dr. Gullotta were known (from the
scientific literature) to be due to the physiological changes that
occurred as a result of a chemical's interaction with certain receptors in
the brain. It is my understanding, that some of the responses observed
by Dr. Gullotta after administration of various levels of nicotine,
appeared to mimic those that had been reported in the literature for
addictive substances like cocaine. A substantial amount of information
regarding the brain's reaction to a wide variety of substances was
generated by these studies, many of the observations going well
beyond what was generally known in the literature (once again,
attesting to Philip Morris' ability to first learn a new technology, and
then to use it to go far beyond what was known to the 'public'). Over
the years, a large number of studies were conducted in this area on
both single chemicals (like menthol and nicotine), while others were
conducted to study the additive or synergistic effect when some of
these chemicals were administered in the presence of other smoke
constituent like CO2.
Dr. Gullotta's pioneering work in this area appeared to demonstrated
that a cause-and- effect relationship could be measured in the central
nervous system between exposure to nicotine and changes in the
electrochemical activity of the human brain. However, Dr. Gullotta's
electrophysiology program was ultimately shut down in Richmond
and moved to a lab in Germany (at INBIFO), ~~presumably because
of the sensitive nature of the results that had been obtained. Dr.
Gullotta told me that he was caught off-guard by the sudden nature of
this decision. I found his action by Philip Morris extremely interesting
in light of the preceding deletion of Dr. DeNoble's animal behavior
project. The nicotine synthesis work of Dr. Seeman was also
discontinued during this same (general) period of time.
23. I observed an 'inner company' within Philip Morris that
appeared to conduct research outside of normal channels. As my own
work at Philip Morris expanded over the years (and placed me in
greater contact with a broad cross-section of the company's facilities
and personnel), I began to notice a pattern of activity within R&D that,
for whatever the reasons, attracted my interest. This was facilitated by:
(1) my daily interactions with a number of Philip Morris researches
both within and external to R&D, as well as (2) my growing
interaction/relationship with Dr. Thomas Osdene and some of the
other members of his staff (including: Ted Sanders, Bob Pages, Bob
McCuen, Jim Charles, among others).
At first, I found it interesting that three, very unique functions at
Philip Morris all reported to Dr. Osdene. This included: (1) the
toxicology (Microsome/Ames Assay) group of Dr. Charles, (2) the
behavioral research lab of Dr. DeNoble, and (3) the electrophysiology
lab of Dr. Gullotta. To the best of my knowledge, no similar groups
existed at any of Philip Morris' competitors (at least with regard to the
latter two). The first group screened a wide variety of tobacco and
cigarette constituents for activity as potential 'promotors' of genetic
change (damage/modification); the second studied the possible
habituating effect of tobacco components (such as nicotine) on the
behavior pattern of animals, and the third group measured the effect of
a variety of tobacco (smoke) constituents on the electrophysiology of
the human brain.
Philip Morris was, in effect, obtaining detailed information about
how its products could at least potentially affect three important levels
of human health: genetics, behavior and the electrophysiology of the
brain. This all became even more interesting when I learned that a
fourth group (headed by Dr. Jeffrey Seeman) had synthesized a
variety of nicotine analogues and had submitted them to Dr.
DeNoble's group for evaluation in their animal behavior studies.
During this period, I also learned (from Dr. Osdene, as well as from
some of his coworkers) that he had been making periodic trips to
Germany to visit 'external partners' that were supporting some of his
(Philip Morris') efforts. Similar trips to other European locations
(such as to the UK) may have also been made. Apparently, this travel
was in addition to the trips that Dr. Osdene occasionally made to
Philip Morris' European headquarters in Switzerland (although they
may, on occasion, have been combined with those trips).
One of these partners was INBIFO. I subsequently found out (by asking around), that hardly anyone knew anything about INBIFO let alone the reason for Dr. Osdene's periodic trips to some of these other European locations. It was my understanding that Jim Charles and/or Bob Pages were also involved in some of this travel. I also remember
hearing that on occasion, some of the results and/or initial observations from some of Dr. Osdene's programs were being communicated verbally, rather than in writing (apparently at the request of Dr. Osdene and/or Dr. Charles).
All in all, it seemed as if there was an 'inner company' within Philip Morris that conducted at least some of its investigations 'behind the scenes' on a strict 'need-to-know' basis. Interestingly enough, many (if not all) of these activities appeared to be related, in one way or
another, to these sensitive topics of 'smoking and health' or to the behavioral impact of nicotine.
I am quite aware that 'inner circles' exist in most companies. However, it seemed to me, that this group of highly placed managers, directors and scientists was planning and coordinating studies that
yielded information about Philip Morris' products (or their
constituents) that could potentially impact the health and well being of
the public (the smoker).
This 'inner company' as I refer to it, first appeared to be coordinated by Dr. Osdene (1970s - early 1980s), and later (mid 1980s - on) by Dr. Charles and encompassed selected individuals both within and external to Philip Morris. I was convinced that some of these groups/individuals (particularly the ones within Philip Morris) may
not have even known that they were being used as the 'extended resources' of this 'inner company', while others (the 'inner circle'), were fully aware of this at least, informal alliance and its activities. It
was also my understanding that some of this group's activities (and
possibly some of the results) were occasionally reported to the VP of
R&D in Richmond and possibly, on other occasions, to selected
individuals in NY so as to keep them informed (at least in a general
manner). However, I was also told (by Dr. Osdene) that some of
these people didn't really want to know all the day-to-day details of
what was going on, but instead, left it in the hands of Richmond (Dr.
Osdene & Co.) to decide what should, or should not be pursued (and
by whom).
24. Corporate (New York) management met regularly in Richmond
to discuss the status of various research, development and
manufacturing initiatives being conducted by PM in the US and
Europe. During my early tenure at Philip Morris, I learned that
corporate executives from New York traveled to Richmond on a
regular, monthly basis so as to keep informed of the status,
accomplishments and/or problems of certain 'high priority' projects
being conducted within, and external to Philip Morris. This included
topics in: (1 ) basic and applied research, (2) product and process
development, (3) manufacturing, and (4) reviews of the results from
test markets in which the relative success or failure of new products
was being evaluated. These meetings (known as the 'Richmond
Meetings') were typically closed affairs and were attended only by the
company's senior management and technical personnel as well as a
few 'invited guests' (an assortment of individuals who, each month,
were asked to report on specific projects of interest to NY).
The New York group typically consisted of the CEO, the President
of PM USA and representatives (VPs/Directors) from such functions
as marketing. They were joined by the senior executive team from
Richmond which normally included: the VP and Directors of R&D,
the VP of Manufacturing and (possibly) some of the Managers and/or
senior technical staff within manufacturing, development and R&D. Principal and Associate Principal Scientists like Dr. William Dunn (Behavior Group), Mr. Howard Spielberg (Flavor Development) and
Mr. Cliff Lilly (R&D) also attended on a regular basis, as did
representative from the Leaf Department and Richmond's legal staff
(local patent attorneys, etc.). On at least some occasions, they would
also be joined by one or more members of the corporate legal staff
from NY. A portion of these meetings would include short (usually
10- 20 minute) presentations made by selected members of the
scientific and/or management staff. These individuals would normally
be present only during their own presentations and then leave
immediately thereafter. The Richmond Meetings would last between
one and two days (depending upon the length of the agenda).
I was asked to give presentations at several 'Richmond Meetings' on
topics ranging from tobacco structure and chemistry, to my work on
the denitrification ('NOD') process. The animal behavior work of Vic
DeNoble and human electrophysiology studies of Frank Gullotta were
also discussed in similar presentations. It is from these personal
experiences, as well as from my discussions with Bill Farone, Tom
Osdene and Cliff Lilly, that I was aware of the nature and content of
some of these meetings. It was clear that corporate (NY) management
had a formal and long-term interest in understanding, as much as
possible, the work that was being conducted by the various research,
development and manufacturing groups within the company. This was
reflected in the many probing questions that were asked by the
corporate attendees at these meetings. In fact, I was surprised (on
more than one occasion) by the sophisticated questions raised by
individuals like Clifford Goldsmith or one of Culmans (attesting to
their focus on what was being presented). These were not just 'Dog
and Pony' shows conducted for appearance only. Quite the contrary, a
great deal of thought and preparation went into the selection and
presentation of these topics which were frequently, quite technical in
nature.
The preceding commentary has-been offered solely in an attempt to
inform others about the general nature of the activities within the
tobacco industry (specifically, Philip Morris) and is not offered, in
any manner, as a personal indictment of the individuals mentioned
herein.
I declare under penalty of perjury that, to the best of my knowledge,-
the foregoing is true and correct. 28 U.S.C. 1746.

The Manipulation and Control of Nicotine and Tar in the Design and
Manufacture of Cigarettes: A Scientific Perspective
by William A. Farone, Ph. D.
It is well recognized within the cigarette industry that there is one
principal reason why people smoke -- to experience the effects of
nicotine, a known pharmacologically active constituent in tobacco.
The recent discussion concerning the regulatory status of nicotine has
led to some confusion over the role of nicotine and tar in the design
and construction of cigarettes. As a scientist who devoted seven years
to the industry as the Director of Applied Research, in the Research &
Development department of Philip Morris U. S. A., part of Philip
Morris, Inc., I would like to put forth a scientific, hopefully objective
assessment of strides made by fellow scientists within the industry.
Research into the importance of nicotine to (he tobacco industry can
be traced to the 1960's when the British American Tobacco Company
initiated research to understand some of the activities of nicotine.1
Clearly by the 1970's and early 1980's the tobacco industry
established that smokers required a minimal level of nicotine within a
cigarette.2
Knowledgeable industry personnel. primarily scientists and blend
and development personnel, understood that a level of nicotine had to
be present to result in a commercially successful cigarette. As publicly
available documents reveal, the tobacco industry began to study how
to design and construct cigarettes to ensure acceptable nicotine levels.3
It was common knowledge within the industry that cigarettes without
nicotine would not sell. Nicotine free cigarettes in the 1950's and 1980's were failures.4
While the negative health consequences of smoking, particularly
emphysema and the increased rate of lung cancer among smokers, are
well known, it should also be noted that smoking, like the use of
fermented beverages and bean and leaf extracts, is a centuries old
phenomenon. The fact that a wide variety of plants contain chemicals
with pharmacological activity can either be regarded as positive or
negative depending on whether one is looking for a cure for disease or
believes that behavior modification is a negative result.
Research by the industry has shown that the pharmacological effects of nicotine have been a two edged sword. The industry understood
that consumers smoke cigarettes because of the pharmacological
properties of nicotine.5 Industry researchers were also aware that the
nicotine found within cigarette smoke may have negative peripheral
nervous system (cardiovascular) effects.6 However, it should also be
pointed out that industry research on nicotine's pharmacological
effects has shown some potential benefits. For example, research
completed by R. J. Reynolds Tobacco Company maintains that
cigarettes provide smokers with psychological benefits, such as
increased mental alertness and anxiety reduction.7 In addition,
research at Philip Morris analyzed the possible benefit of nicotine
related to hyperkinetic children as well as nicotine's beneficial effects
on reducing stress experienced by smokers and improving the
performance of tasks.8
If we accept the premise -- as the cigarette industry surely does -- that
cigarettes are a nicotine delivery system, and that current laws do not
forbid the self administration of nicotine via smoking by adults, then it
becomes a desirable technical challenge to decrease the "tar" in a
cigarette while maintaining the delivery of nicotine. I his has been a
key objective of the cigarette industry over the last 20-30 years, as
some industry documents now publicly reveal.9 Minimizing the
exposure to the potential negative health effects of the undesirable
chemical components in tar while maintaining an acceptable and
pharmacologically active nicotine level is thus a valid and useful
technical challenge that I and many of my former colleagues in the
cigarette industry considered a top priority.
Achieving this acceptable and pharmacologically active nicotine level
was an enormous challenge. It required cigarette manufacturers to
deliberately control the levels of nicotine in their products in order to
overcome the naturally-occurring variability of nicotine in tobacco
plants. Since tobacco is a natural product and the content of nicotine
varies from year to year. by type of tobacco, by varieties within types.
and from farm to farm it is also necessary to be able to control nicotine
levels and the ratio of nicotine to tar to be able to make a consistent
product and to accurately label the product for nicotine and tar as
required by law.
Cigarette manufacturers have invested enormous financial resources to achieve the desired level of control over nicotine and tar in their products. The industry employs two principal means of controlling the nicotine levels:
1. By modification and control of the tobacco blend, i.e., the ratio of
Burley (air cured), Bright (flue cured), Oriental, stems, expanded
tobacco products, and reprocessed tobacco products such as tobacco
sheet made from stems and waste leaf.
2. By modification of the construction of the cigarette such as filter
type, the type of filter material used, the number and placement of
ventilation holes the density composition and porosity of the cigarette
paper, the length and diameter of the paper and the types and amounts
of flavor additives.
Over the years, these techniques have been described or discussed in
the public domain at various meetings and by publications in books,
patents. scientific papers. and newspapers.10
The strongly held conviction of most industry scientists and product
developers was that nicotine was the primary reason why people
smoked. This was sometimes openly expressed.11
In fact, it was commonly understood within the industry that the smoker's acceptance of a cigarette was related to the amount of nicotine it contained. Extensive in some instances ground breaking, research by the tobacco industry was necessary to construct a cigarette that ensured an adequate delivery of nicotine as the cigarette market
evolved from the traditional full flavored, unfiltered product of the 1950's to the filtered, low tar cigarette demanded by many smokers for the last 30-40 years. I he objective of industry scientists and product
developers, simply stated, was to provide the consumer with the same
pharmacological satisfaction derived from nicotine in the natural
blends and flavor of the full strength cigarettes of the 1950's as the
marketplace shifted to the naturally less flavorful and satisfying low
tar and nicotine cigarette demanded by the more health conscious
consumer.
A major contributor to this process was Dr. William Dunn, Principal
Scientist and manager of the Behavioral Research group of Philip
Morris. Dunn believed that nicotine was a beneficial component of
cigarette smoke.12 Tar was considered to be the "biologically active," i.e. harmful component of cigarette smoke. Therefore. the
development of low tar cigarettes that gave the smokers the nicotine
they wanted but exposed them to less tar were considered good
research and product development objectives. Industry scientists were
proud to be working on the development of these products.
Discussions at industry or company sponsored meetings such as the
Tobacco Chemists Research Conferences often occurred among blend
specialists. market researchers. and research & development scientists
on how to attain that level of acceptability while reducing the tar. An
attempt by R. J. Reynolds to produce the ultimate low tar cigarette
was the PREMIER nicotine delivery device. PREMIER which was
test marketed by RJR, delivered virtually no tar at nicotine levels
slightly lower than currently marketed fuller flavor low tar
cigarettes.13 According to news reports, Philip Morris was also
working on their own version of PREMIER, code named TABLE.14
While working at Philip Morris, Dunn and his behavioral science
group promoted the need to provide adequate levels of nicotine in the
product, and to maintain adequate levels of nicotine in order to keep
smokers satisfied. This concept of nicotine delivery being essential to
consumer satisfaction was common knowledge within Philip Morris
and the rest of the industry.15 When consumer testing indicated that a product was lacking in "impact" or some similar descriptor that could be associated with nicotine experienced market researchers and product developers would compensate by increasing nicotine levels to provide the necessary impact in future versions of that product.
As in any discipline, basic pharmacological research was necessary to properly understand a phenomenon. The industry applied considerable effort and manpower to the study of nicotine in order to understand this relationship between nicotine and the smoker's needs.
Many internal industry documents that have recently become publicly
available reflect, in part, the novel and extensive research conducted.
Philip Morris undertook research into nicotine's effect on brain
waves, brain receptors, the cardiovascular system, physiological
impact, juvenile hyperkinesis, alleviating anxiety, stress, and
aggression, the smoker's motivation to continue smoking, as well as
on the smoker's cognitive abilities.16 R. J. Reynolds (RJR) research
involved human experimentation including analyzing nicotine blood
levels and nicotine urine levels as well as the identification of specific
brain receptor locations involving the binding sites for nicotine.17
British American Tobacco Company (BATCO), the parent company
of U. S.-based Brown & Williamson Tobacco Co., sponsored
pioneering work into the addictive nature of nicotine more than 30
years ago and Philip Morris later conducted state-of the-art animal
studies demonstrating that nicotine is a "positive reinforcer," and that
this effect is centrally mediated one of the defining characteristics of
addictive drugs.18
This basic research provided product developers with the scientific
foundation that was necessary to help construct a low tar cigarette that
maintained an adequate level of pharmacological activity from nicotine
in reduced tar products. Product developers and blend and leaf
specialists were responsible for manipulating and controlling the
design and production of cigarettes in order to satisfy the consumer's
need for nicotine in lower yield products.
Blend changes were an especially important tool used to ensure
desired nicotine levels. Tar is a function of tobacco weight. However,
an all-burley cigarette will produce a higher nicotine level than an all-
bright tobacco cigarette of the same weight. The industry knew that by
using a higher percentage of higher nicotine tobacco in their low tar
cigarettes they could achieve an increase of their nicotine levels.
Therefore a blend change incorporating the greater use of higher
nicotine tobacco while reducing the overall tobacco weight, such as
through the use of expanded tobacco, could produce a low tar cigarette
with the desired pharmacologically active level of nicotine associated
with a conventional full flavor cigarette. An example is the Merit Ultra
Light which was introduced in 1981 with an elevated nicotine to tar
ratio of 0.11.[19] In fact, Philip Morris utilized much of the
technology and expertise of leaf and flavor chemistry and behavioral
research to mask the harsher taste associated with the presence of
higher nicotine burley tobacco in the blend of Merit.20
The cigarette industry also altered the cigarette filter in order to
increase nicotine delivery. As the public literature describes, the
industry knew that "selective filtration" was possible.21 Filter design
and ventilation allowed the design and manufacture of cigarettes that
removed a higher percentage of tar than nicotine. Selective filtration
was accomplished by altering the technical specifications for a filter,
e.g. by selecting different filter tow combinations, varying the denier
per filament, and deciding whether or not to use additives in the filter.
After the blend was selected, appropriate filters were identified to
attain a predetermined nicotine/tar ratio. Manufacturers of cigarette
filter materials produced detailed technical presentations promoting
filters that provided higher nicotine to tar ratios by selectively filtering
out more tar. As noted above. the public literature describes these
techniques.22
Another component of cigarettes that is used to control nicotine
delivery is reconstituted tobacco. The tobacco industry originally
developed reconstituted tobacco as a cost- saving measure. Over the
last several decades the industry has used reconstituted tobacco
products to assist in controlling the nicotine delivery in cigarettes.
Reconstituted tobacco is composed of returned cigarettes, tobacco
stems, scraps, and dust. By use of either a wet paper making process
or a bandcast process these scraps are made into tobacco sheet or
reconstituted tobacco.23 By controlling the ingredients that go into
making reconstituted tobacco, the industry controls the chemical and
physical properties of the finished sheet, including its nicotine content.
For example, reconstituted tobacco used in a low tar cigarette blend
can be made differently from the reconstituted tobacco used in a full
flavor cigarette. The reconstituted tobacco blend destined for a low tar
cigarette can be made with a higher concentration of burley tobacco
scraps than the blend of reconstituted tobacco designated for a full
flavor brand. Reconstituted tobacco is closely controlled for its
chemical properties and burn rate and flavor controlling additives. The
alkaloid (mostly nicotine) and sugar content of all the scrap used can
be measured and precisely blended into reconstituted tobacco. The
levels of nicotine and other key compounds can also be measured to
insure control in reconstituted tobacco. Quality control checks
involving the use of a gas or liquid chromatography to ascertain the
exact nicotine amounts are routinely employed during the process.
Final product that fails to meet the design specifications for nicotine
can be returned to the start of the process or re-blended.
The delivery of tar and nicotine is a complicated scientific problem
and recent reports are now shedding more light on how the problem
was solved. The use of ammonia chemistry was important to the
industry in maintaining adequate nicotine delivery lo satisfy
smokers.24 The industry was able to deliver more of the available
nicotine in the blend to the smoker by using ammonia compounds.
This apparently works by increasing the pH of the tobacco smoke.
Commonly, the pH (or level of basicity) is increased by the addition
of ammonia compounds either as additives or in the manufacture of
reconstituted tobacco. Ammonia is sometimes introduced by casings
such as urea that are applied to tobacco and then decompose into
ammonia at which point they can increase the pH of the smoke. These
casings include ingredients like amino acids, proteins, and other
products that decompose or by pyrolysis are changed into pH
increasing agents, such as ammonia. In the complex world of tobacco
smoke chemistry, by increasing the pH I of the aerosol in the
mainstream smoke, more of the aerosol would be in the vapor phase
and less in the liquid (or condensed) phase. By increasing the ratio of
vapor phase to liquid phase, one increases the total nicotine delivery
since the condensed phase is less likely to survive the filter and the trip
to the lungs.
All of the cigarette components described above were incorporated
into complex computer models to help determine nicotine and tar
deliveries while cigarettes were in the product development stage.
These models allowed blend ingredients, filter and paper components,
and numerous other variables to be considered simultaneously. The
models enabled nicotine and tar deliveries to be successfully predicted
and enabled product developers to identify which components were
required to produce specific nicotine and tar deliveries. Models of this
type are well suited to the use of computers and are discussed in the
published literature.25
The tobacco industry found that in the manipulation of the
nicotine/tar ratio, the methods used to increase the nicotine to tar ratio
sometimes resulted in a cigarette that was too harsh. With a standard
nicotine/tar ratio in a traditional cigarette no flavor smoothing
compounds are generally needed to produce a palatable cigarette. The
higher tar levels in traditional cigarettes mask the harshness of nicotine
and the associated compounds produced in higher nicotine to tar
ratios. A low tar cigarette with a higher nicotine/tar ratio than a
traditional cigarette could be very harsh due to the lack of sufficient
specific tar components to mask the nicotine and related basic
compounds. To overcome the harshness due to the increased burley in
the blend, the industry used flavor "smoothers."26
While some of the research into the construction and design of the
low tar cigarette is now becoming publicly available, much of the
novel and groundbreaking scientific research of the tobacco industry
has not come to the public's attention. The sequestering of much good
science within the industry can be traced to fears within the industry
that this research might be used in litigation against the industry.
Recent documents and stories have come to light that illustrate the
quandry faced by tobacco industry management. The argument is that
any company should not create or be exposed to information that may
come back to haunt them in civil litigation. The closing down of Dr.
Victor DeNoble's nicotine studies at Philip Morris and the screening
of British American Tobacco (BATCO) scientific reports by Brown &
Williamson attorneys as described by Dr. Jeffery Wigand are two well
known examples.27
The point, however, is that much of this research is beneficial to the smoker if we concede the premise that smoking is lawful and enjoyable to many people.
In other countries smoking research is treated in a much more open manner and this has led to a great deal of smoking research being performed outside the U. S. Some countries require testing of flavor additives, including tests on animals. In Japan, where the government
controls the tobacco monopoly, the research on lowering
carcinogenicity is discussed openly.
Tobacco industry scientists conducted research utilizing
electroencephalograms (EEG's) in the 1970's.28 The initial theory behind EEG research was to expand upon published research that nicotine had a beneficial effect on brain wave patterns. The work was demonstrating that positive brain wave patterns could be achieved with persons who smoked a cigarette and were then required to undertake
difficult tasks. The workers tested three cigarettes with the same tar level but varying levels of nicotine. Subjects who smoked the cigarettes were monitored by EEG. This research is valuable because as the EEG testing became more sophisticated, the EEG might be used to determine whether cigarettes had adequate levels of nicotine, and whether a particular ingredient was a nicotine enhancer or nicotine
substitute.
Research of this type can be carried out in foreign countries, or in an
environment where fear of lawsuits do not override the need to
improve products. In an "open" environment, with cooperation on the
nature of cigarette products between the industry and government
regulators, research of this type could be used to "optimize" the
cigarette for those who continue to desire to smoke. Rather than
restrict the options of what companies could do, agreement between
regulators and industry would open up entirely new options for
cigarette construction and progress in the industry.

Declaration
Jerome Rivers declares as follows:
1. I was employed by Philip Morris for 23 years. My employment
at Philip Morris began in 1972 and ended in 1995. During this period,
I held numerous positions at Philip Morris, including positions in
Research and Development, Production, and Technical Support.
2. From 1991 to 1995, I served as a shift manager at Philip
Morris's blended leaf (BL) plant in Richmond, Virginia. The BL plant
was used to make a type of reconstituted tobacco called blended leaf or
"bandcast."
3. The BL plant operated 24 hours a day. As a shift manager, I had
responsibility for and personal knowledge of the operations of the
plant during a shift.
4. The ingredients used to make blended leaf are the by- products
from the manufacturing of cigarettes, such as tobacco stems, small
tobacco particles, and tobacco dust. At the BL plant, these by-
products are blended together according to formulas provided to the
shift manager by Philip Morris's Technical Support Group.
5. After the by-products are blended together, the by- products are
mixed with water and other ingredients, including flavorings, to form
a slurry. One of the ingredients regularly added to the slurry at the BL
plant was ammonia. Other ingredients included alcohol-based flavors,
sugars, urea, and glycerine.
6. The slurry is spread onto a stainless steel belt and passed through
a dryer. After the slurry dries, it is taken off the belt and cut up into
sheets to form the reconstituted tobacco sheet.
7. The reconstituted tobacco sheet is time-stamped and shipped to
Philip Morris cigarette factories, where it is blended into cigarettes.
8. At the BL plant, Philip Morris made about half a dozen different
reconstituted tobacco sheets. These sheets would use different
blending formulas. For instance, one formula would require the use
of more by-products from Burley tobacco, while another formula
would require the use of more by-products from Bright tobacco. The
formulas might also have differences in the chemical ingredients added to the by-products.
9. During the manufacture of reconstituted tobacco, we frequently
monitored the alkaloid content of the by-products, the slurry, and the
final reconstituted tobacco sheet. Alkaloid is another name for
nicotine. The alkaloid content would be measured using a gas
chromatograph located in a laboratory in the BL plant.
10. We would measure the alkaloid content of the by- products
approximately once a shift. We would measure the alkaloid content of
the slurry approximately once per hour. We would also measure the
alkaloid content of the final product approximately once per hour.
11. The alkaloid measurements would be returned to us soon after
we had taken a sample. It generally took only 10 to 15 minutes to get
the results back.
12. We would record the alkaloid content of the reconstituted
tobacco sheet in a computer database. This database recorded the
alkaloid content of each time-stamped package of blended leaf.
13. Philip Morris established standards or "specs" for the alkaloid content of the reconstituted tobacco sheet blended leaf product. If our measurements showed that the product was out-of-spec for alkaloids, we would pull the reconstituted tobacco sheet. We would usually then feed the out-of-spec reconstituted tobacco sheet back into BL process in small quantities so that it could be made into a new reconstituted tobacco sheet meeting the alkaloid specs.
14. If the sampling of the by-products indicated that alkaloid content
of the by-products did not meet the specs established for the by-products, we would inform the Technical Support Group. The Technical Support Group would fax us a new blending formula. For instance, if the by-product sampling indicated a downward trend in the nicotine content of by- products from Bright tobacco, we might be instructed to add more Burley by-products to the blend. Burley by-
products contain more nicotine than Bright by-products.
15. Philip Morris also operated a plant at Park 500, in Richmond, Virginia, for making another type of reconstituted tobacco called reconstituted leaf. I attended meetings at which the operations of Park 500 were discussed. From these meetings, I learned that Philip
Morris also operates a gas chromatograph at Park 500. As at the BL plant, Philip Morris uses this equipment at Park 500 to measure the alkaloid content of the reconstituted leaf.
16. I declare under penalty of perjury that, to the best of my knowledge, the foregoing is true and correct. 28 U.S.C. sec. 1746. Executed on March 7, 1996.
