A Short History. . of the
Nonsmokers' Rights
Movement
In the early 1970's, nonsmokers began to realize that there might
be an alternative to spending their liv'~es under a cloud of tobacco
smoke. Heartened by the mounting evidence of the dangers of smok-
ing, the elimination of cigarette advertising on radio and television
and the first studies showing possible harm to nonsmokers from to-
bacco smoke, a loose coalition of grass roots nonsmokers' rights or-
ganizations formed in various communities throughout the United
States. Most of these organizations had only a handful of members,
who were pioneers in a new social movement. Their task was not
so much to limit public smoking -- that was not yet possible
but rather to persuade fellow nonsmokers that public smoking was
an important problem. Remember: less than 15 years ago, close to
half the adult population smoked cigarettes (it is closer to one-third
today) and there was hardly any public place (much less a place of
employment) where smoking was restricted. At that time, it took
great courage for someone to ask another person not to smoke - in
a private or public place.
The movement attracted a large following in a short time. Al-

2 CHAPTER 1. HISTORY
though the tobacco industry did not take it seriously as long as it
consisted of persons passing out leaflets and buttons, it was forced
to take notice when the State of Minnesota enacted a law in 1975
that restricted smoking in most indoor public places and required
the establishment of nonsmoking sections in the workplace, for both
public and private employers. Minnesota has no real economic inter-
est in the tobacco industry, and an energetic and resourceful state
legislator was able to push the bill through the legislature with little
fanfare. Unfortunately, this was the last time the industry would be
caught napping.
It did not take long for the tobacco industry to realize the danger
posed by such a law and to realize that if it did not do something,
many similar laws would soon be passed throughout the country.
The potential power of the nonsmokers' rights movement was clearly
brought home in a secret 1978 report prepared by the Roper Orga-
nization for the Tobacco Institute, the industry's trade association.
Among other things, the report found:
Almost two-thirds of nonsmokers believed second-hand smoke
to be harmful.
. There was majority sentiment for having separate smoking sec-
tions in all public places covered by the report.
. More people said that they would vote for than against a polit-
ical candidate who takes a position favoring a ban on smoking
in public places. '(Remember that this was in 1978, before all
the string of legislative successes - and point this out to leg-
islators whose support you seek.)
. Favorable attitudes toward the tobacco industry were at their
lowest ebb. (They are certainly even lower today.)
The report demonstrated that the early nonsmokers' rights activi-
tists were correct in realizing that they had to raise the consciousness
of other nonsmokers, because the report showed that there was rel-
atively little public concern over the smoking issue compared with
3
other social issues such as crime, drugs and pollution. (Of course, the
report should have noted that the smoking issue also involves drugs
and pollution.) But the report also demonstrated that those early
activists had, at the very least, succeeded in convincing a large pro-
portion of nonsmokers that second-hand smoke is hazardous. Non-
smokers' rights activists received a tremendous psychological boost
in knowing they no longer consisted of small voices crying in the
wilderness. Ironically, the boost was provided by the tobacco indus-
try itself.
The most important part of the Roper Report was its conclusion
that the nonsmokers' rights movement was the single greatest threat
to the viability of the tobacco industry. In other words, laws and
social pressures restricting smoking in public places would hurt the
industry more than all the health warnings to smokers! There are
two reasons why this is so:
The first, and rather obvious, reason is that as smoking is re-
stricted, smokers will have less opportunity to smoke and thus will
smoke fewer cigarettes per day. As an executive of R.J. Reynolds
pointed out in 1984, if nonsmoking laws had the effect of cutting
consumption by just one cigarette per smoker each (lay, the industry
would sell 22 billion fewer cigarettes each year!
The second reason is both more subtle and more significant: the
nonsmokers' rights movement and concornmitant legislation make
smoking socially unacceptable. The tobacco industry had long ago
figured out how to successfully combat the health warnings of the
medical profession, but it knew it could not abide an attack on the
very reason for smoking - that it was suave and sophisticated and
that people who smoke were popular. If smokers could be made to
feel like outcasts - driven to the far corner of a room to indulge in a
filthy habit - they would soon find the fortitude to quit altogether.
The industry might survive reduced consumption, but it could not
survive if it were to lose its customers altogether.
The Roper Report remains one of the key documents in the battle
for nonsmokers' rights and is must reading for anyone who is seriously
involved in the nonsmokers' rights movement. (For a complete copy
of the report, see Appendix A.)

4 CHAPTER 1. HISTORY
Thus, by the mid-1970's, the battle was joined, and the industry
would never again sit idly by while a nonsmokers' rights law was
passed. Tobacco industry lobbyists began appearing in nearly every
location where legislation was being considered. Even with increased
public awareness of the issue, most nonsmokers' rights organizations
were unable to attract politically powerful supporters and were usu-
ally no match for the sophisticated lobbying campaigns of the tobacco
industry, particularly at the state level. As a result, efforts to enact
legislation in the latter half of the 1970's were usually met with hos-
tility and indifference; with few exceptions, legislation either failed
altogether or was so diluted as to be almost meaningless.
In 1978, after being frustrated in an attempt to enact statewide
legislation, the organization which later became Americans for Non-
smokers' Rights placed a comprehensive nonsmokers' rights measure
on the California statewide ballot by means of the initiative process.
The 600,000 signatures obtained (twice the number needed) and the
early large approval of the measure in public opinion polls were clear
evidence that nonsmokers' rights had come of age with the public.
What nonsmokers were not prepared for, however, was the outra-
geous campaign against the measure conducted and financed by the
tobacco industry. By the time the smoke cleared, the industry had
spent $6.5 million and had literally bought the election. The initia-
tive was defeated by a margin of 54 percent to 46 percent. At the
same time, a group in Dade County, Florida also put a measure on
the ballot and also suffered a defeat, although by an even slimmer
margin, 51 percent to 49 percent. Both organizations, having come
so close to winning, came right back and placed similar measures on
the 1980 ballot, but both lost again, by almost identical margins.
Nonsmokers learned the hard way that they could not easily com-
pete with the tobacco industry in what amounted to expensive mass
media campaigns. Not only is the industry highly skilled in using
mass media to begin with (it spends more than $2.5 billion per year
advertising cigarettes), but it is able to use the media to distort the
facts and to confuse the electorate. As any politician will tell you, a
confused voter will invariably vote "No." Nonsmokers also learned
just how expensive election campaigns can be, and how much volun-
teer teer time and energy is necessary to run them. The initiative cam-
paigns were glamorous, but ultimately unsuccessful and dishearten-
ing. It was time for a new strategy.
In 1981, the leaders of the two California initiative campaigns
formed Californians for Nonsmokers' Rights (renamed Americans for
Nonsmokers' Rights in 1986), and returned to the legislative pro-
cess by concentrating on passing ordinances at the city and county
level. The mounting medical evidence of the dangers of second-hand
smoke and the increased public awareness of those dangers (largely
generated by the two election campaigns) had paved the way for
the passage of effective laws. Californians for Nonsmokers' Rights
soon discovered that the further down you go in the governmental
structure, the less influence the tobacco incJustry has and the more
influence individual constituents have. While at the state level indus-
try lobbyists and money can severely impact legislators, city council
members and county supervisors often refuse even to talk to indus-
try lobbyists, and are far more inclined to listen to the arguments
of local citizens. Nonsmokers found that when they were sufficiently
organized and personally lobbied local legislators, they were able to
pass legislation in almost any community, often by unanimous votes.
In less than five years, more than 75 ordinances were passed through-
out California, in places ranging in size from towns with only a few
thousand people to cities as large as Los Angeles.
The major turning point, however, was in November 1983, when
the tobacco industry put a referendum on the ballot (Proposition
P) in an attempt to overturn a workplace smoking ordinance which
had been passed in San Francisco. Even though the industry spent
more than $1.1 million and outspent the supporters of the law by
more than ten to one, the voters approved the ordinance and handed
the industry its first election defeat. Because the referendum took
place in a large, highly-visible city, and in a non-election year, it re-
ceived national, and even international, attention. This one event,
more than anything else, showed the popularity of nonsmokers' rights
laws and demonstrated the vulnerability of the tobacco industry. It
opened the door for the passage of many more ordinances in Califor-
nia and heightened interest in legislation around the country. (For
I

6 CHAPTER 1. HISTORY
an analysis of the Proposition P campaign, see Appendix B.)
And, of course, there have been many other laws passed in other
parts of the country by various nonsmokers' rights organizations.
(For charts showing the places and types of major legislation, na-
tionally and in California, see Appendix C.) In 1984, the industry
again tried to overturn a law that had already been passed, this time
in Fort Collins, Colorado. The voters there recorded a resounding
64 percent approval of the law and, perhaps, dissuaded the industry
from attempting any future referenda.
These recent successes should point the way toward a surge of
legislative activity that could literally put a damper on smoking in
public places and workplaces throughout the country. In the current
climate of public opinion, it is possible to pass comprehensive non-
smokers' rights legislation in almost any community in the United
States, provided the effort to do so is well-organized by knowledgable
people.
To those of you who are just beginning to consider involvement
in the legislative process, two items of encouragement are offered:
First, as the 1978 Roper Report indicated, most people do not
view nonsmokers' rights as a highly important issue, and the tobacco
industry will play this fact to the hilt. Before you finish your task,
someone is bound to ask why you don't work on something "im-
portant." But you need not be at all defensive as to why you are
working for nonsmokers' rights. There are good reasons why non-
smokers' rights is a vital issue even if most people do not view it as
such, and you should not hesitate to point these out when the ques-
tion arises. The most obvious reason is that you are working on a
public health measure that affects everyone in our society. But just
as important is the fact that what you are doing is directly attacking
the tobacco industry, and that means cutting down on the hundreds
of thousands of cigarette-related deaths that occur each year. Since
cigarettes kill more Americans every three years than have died in
all the wars this country has ever fought, anything that can be done
to reduce those deaths is worthwhile. Moreover, a side benefit of im-
proving the health of both nonsmokers and smokers is reduced health
care costs and reduced taxes. And, of course, nonsmokers' rights is
7
important to you and your own health. That is reason enough to be
involved.
Second, not only is nonsmokers' rights legislation possible, but
it can be accomplished by a small number of very dedicated people,
without too many resources beyond their ingenuity and stubborn-
ness. If you are willing to face temporary setbacks and frustrations,
you will succeed. The tobacco industry knows it is fighting a rear-
guard action. If you stick to it, you will eventually pass nonsmokers'
rights legislation no matter how bleak the prospects might sometimes
seem.

The Health Hazards of
Second-Hand Smoke
It has long been known that high levels of outdoor air pollution
from factory chimneys and automobiles can cause illness and even
death. These serious effects of air pollution have led to federal stan-
dards for the regulation of outdoor exposure levels, and considerable
progress has been made in curtailing outdoor air pollution. How-
ever, we spend 90 percent of our lives,indoors. Therefore, the levels
of indoor air pollution assume great importance in determining total
exposure to many air pollutants.
Indoor air pollution from tobacco combustion not only is chemi-
cally related to the smoke from factory chimneys and other sources of
outdoor air pollution, but generally occurs at far higher levels indoors
than does factory smoke and automobile exhaust outdoors. Because
one-third of the U.S. adult population smokes, and because ventila-
tion rates are primarily designed to conserve energy rather than to
preserve indoor air quality, the smoke from burning cigarettes, pipes
and cigars overwhelms the capability of typical building ventilation
systems, inflicting substantial air pollution burdens on nonsmokers
- far in excess of those encountered in indoor environments free of
tobacco smoke, outdoors generally or in vehicles on busy commuter
highways.l

10 CHAPTER 2. SECOND-HAND SMOKE 11
There are more than 600 medical and scientific studies of the
effects of second-hand smoke (see Appendix D for a bibliogra-
phy). This evidence has been reviewed by several independent sci-
entific bodies, including the Office of the United States Surgeon
General,2-4 the National Academy of Sciences5 and the World Health
Organization,6 all of which have concluded that involuntary expo-
sure to tobacco smoke represents a significant public health prob-
lem. (The tobacco industry has sponsored "international workshops
in Geneva and Vienna" which it claims have come to different con-
clusions. For a discussion of these workshops and how to invalidate
industry arguments based on them, see Chapter 4.)
Surgeon General C. Everet Koop succinctly summarized this ev-
idence in a letter written in 1986 as follows:7
The harmful constituents of mainstream cigarette
snioke [which the smoker inhales] are found in sidestream
smoke [which the nonsmoker inhales], sometimes to a
greater extent than in mainstream smoke.
Pollution from tobacco smoke in homes, offices, other
worksites and in certain public places can reach levels
which exceed contaminant levels permitted under envi-
romnental and occupational health regulations.
Nonsmokers absorb the constituents of tobacco smoke
into their bodies, even though in smaller amounts than
is true for those who smoke.
Maternal smoking has harmful effects on pregnancy,
including an increased risk of miscarriage, prematurity,
stillbirth, death soon after birth, low birth weight, and
fetal death.
There is increasing evidence to suggest that environ-
mental tobacco smoke can bring disease, including lung
cancer, in healthy adults, children and infants.
It is on the basis of these facts that I advise nonsmok-
ers to avoid exposure to cigarette smoke wherever possi-
ble, and that, in particular, they should protect infants
and children from this smoke.
(Appendix E contains the full text of this letter, which makes
a useful handout to legislators and the press. Appendix F contains
a brochure summarizing the health effects of second-hand smoke.
Appendix G contains testimony on the health effects of second-hand
smoke presented at a hearing before a U.S. Senate subcommittee.)
What's In the Smoke That Nonsmokers Breathe?
Cigarette smoke contains approximately 4000 chemicals, many
of them poisons.2,3 The burning end of a cigarette releases twice as
much sidestream smoke directly into the air as mainst.ream smoke,
which is inhaled directly through the cigarette by the smoker.
Sidestream smoke is then breathed by the nonsmoker in amounts
that depend on how many cigarettes are burning at a time; how
close the nonsmoker is to the source of the snioke; and the size,
shape and ventilation of the space involved.8 The sidestream smoke
that the nonsmoker inhales is even more toxic than an equal amount
of mainstream smoke.2 This is due to the fact that when a cigarette
is smoldering in an ashtray (which is about 95 percent of the time
that a cigarette is lit), it burns at a lower temperature than when
it is being inhaled (because air is being drawn through the burning
tobacco), so there is less complete, and hence dirtier, combustion.
The poisons in second-hand smoke include:2
Carbon Monoxide: This is a colorless, odorless and highly poisonous
gas which lowers the amount of oxygen carried by the blood.
It does this by beating oxygen to the red blood cell "posi-
tions" which normally carry oxygen in the blood. If someone
stays in a closed garage with an auto engine running, it is the
carbon monoxide which kills the person. Carbon monoxide is
the poison that makes people have headaches from breathing
second-hand smoke.
Nicotine: This is the addictive drug that maintains the tobacco
habit. It makes the heart beat faster and work harder than

12 CHAPTER 2. SECOND-HAND SMOKE
it should, and it adversely affects blood clotting factors which
may play a part in heart attacks.
Carcinogens: There are dozens of carcinogens (cancer-causing agents)
in tobacco smoke. One of the most potent of all carcinogens is
benzopyrene, discovered in tobacco smoke more than 30 years
ago.
Hydrogen Cyanide: This is the gas often used to execute prisoners in
gas chambers. In the amounts found in tobacco smoke it kills
cilia, the tiny hairs that move together in waves to help keep
our lungs clean.
Arsenic: This is a potent poison.
Pesticides: There are numerous pesticides in tobacco smoke, includ-
ing DDT, paraquat, endrin, parathion and endosulfan, espe-
cially when the tobacco is imported from countries that do
not restrict their use.
Radioactive Compounds: Such compounds as polonium 210 and pot-
assium 40 are known to cause cancer.
As the accompanying table shows, there is much more of some to-
bacco smoke poisons in sidestream smoke than in mainstream smoke.
How Much Exposure Do Nonsmokers Get?
Obviously, the exposure of nonsmokers to tobacco smoke will
vary a great deal, according to the factors listed above. Practically
all nonsmokers are involuntary smokers to some extent. Some are
lucky enough to get very little exposure to tobacco smoke. But for
many the exposure is heavy, frequent and largely unavoidable.
Investigations of indoor air quality have shown that tobacco
smoke is clearly a major source of indoor air pollution for most
people.1,9-s

For example, levels of carbon monoxide in the air often exceed
federal standards when cigarettes are being smoked, even in well-
ventilated rooms, and may occasionally exceed recommended max-
imum limits for an eight-hour exposure at work.2 Levels of carbon
monoxide in smoky rooms are commonly about three times those
found close to city roadways.
A major study on indoor air pollution done at the Environmental
Protection Agency in 1980 in various common settings, such as work-
places and restaurants, found that "levels of respirable suspended
particulates [smoke particles] in places where tobacco is smoked
greatly exceed levels found in smoke free environments, outdoors
and vehicles on busy commuter highways." ' In contrast, the indoor
air always met federal outdoor clean air standards when no one was
smoking.
Involuntary exposure to cigarette smoke is sometimes expressed
as the equivalent of the number of cigarettes "srnoked" by measuring
the quantity of tobacco smoke in the air breathed by the nonsmoker
