-
- The following is the text of a pamphlet I wrote for an organization
- at UMASS amherst
-
- It is an attempt to point out some of the absurdities in the marijuana-
- is-bad-for-you-like-cigarettes bullshit, as well as take a few cheap
- (but well aimed) shots at the tobacco industry.
- It is written from a pro-marijuana-relegalization perspective,
- and if you want a copy, mail us a Self Addressed Stamped Envelope.
- (we're poor.)
-
- An address and some sources are at the end.
-
- So, you thought it was the tar that caused cancer...
-
- Think again. Cigarette companies will have you believing
- anything just as long as you continue to buy their products. The
- fact is, although insoluble tars are a contributing factor to the
- lung cancer danger present in today's cigarettes, the real danger
- is radioactivity. According to U.S. Surgeon General C. Everette
- Koop (on national television, 1990) radioactivity, not tar,
- accounts for at least 90% of all smoking related lung cancer.
- Tobacco crops grown in the United States are fertilized by law
- with phosphates rich in radium 226. In addition, many soils have
- a natural radium 226 content. Radium 226 breaks down into two long
- lived 'daughter' elements -- lead 210 and polonium 210. These
- radioactive particles become airborne, and attach themselves to the
- fine hairs on tobacco leaves.
- Studies have shown that lead 210 and polonium 210 deposits
- accumulate in the bodies of people exposed to cigarette smoke.
- Data collected in the late 1970's shows that smokers have three
- times as much of these elements in their lower lungs as non
- smokers. Smokers also show a greater accumulation of lead 210 and
- polonium 210 in their skeletons,though no studies have been
- conducted to link these deposits with bone cancer. Polonium 210 is
- the only component of cigarette smoke which has produced tumors by
- itself in inhalation experiments with animals.
- When a smoker inhales tobacco smoke, the lungs react by
- forming irritated areas in the bronchi. All smoke produces this
- effect. However, although these irritated spots are referred to as
- 'pre-cancerous' lesions, they are a perfectly natural defense
- system and usually go away with no adverse effects. Insoluble tars
- in tobacco smoke can slow this healing process by adhering to
- lesions and causing additional irritation. In addition, tobacco
- smoke causes the bronchi to constrict for long periods of time,
- which obstructs the lung's ability to clear itself of these
- residues.
- Polonium 210 and lead 210 in tobacco smoke show a tendency to
- accumulate at lesions in specific spots, called bifurcations, in
- the bronchi. When smoking is continued for an extended period of
- time, deposits of radioactivity turn into radioactive 'hot spots'
- and remain at bifurcations for years. Polonium 210 emits highly
- localized alpha radiation which has been shown to cause cancer.
- Since the polonium 210 has a half life of 21.5 years (Due to the
- presence of lead 210), it can put an ex-smoker at risk for years
- after he or she quits. Experiments measuring the level of polonium
- 210 in victims of lung cancer found that the level of 'hot spot'
- activity was virtually the same in smokers and ex-smokers even though
- the ex-smokers had quit five years prior to death.
- Over half of the radioactive materials emitted by a burning
- cigarette are released into the air, where they can be inhaled by
- non-smokers. In addition to lead 210 and polonium 210 it has been
- proven that tobacco smoke can cause airborne radioactive particles
- to collect in the lungs of both smokers and non-smokers exposed to
- second hand smoke. Original studies conducted on uranium miners
- which showed an increased risk of lung cancer due to exposure to
- radon in smokers have been re-run to evaluate the radioactive lung
- cancer risk from indoor air radon. It turns out that tobacco smoke
- works as a kind of 'magnet' for airborne radioactive particles,
- causing them to deposit in your lungs instead of on furniture.
- (Smoking indoors increases lung cancer risks greatly.)
- It has been estimated that the total accumulated alpha
- radiation exposure of a pack-a-day indoor smoker is 38 to 97 rad by
- age 60. (Two packs a day yields up to 143 rad, and non-smokers
- receive no more than 17 rad.) An exposure of 1 rad per year yields
- a 1% risk of lung cancer (at the lowest estimate.)
- Don't smoke. Or if you do, smoke lightly, outdoors, and
- engage frequently in activities which will clear your lungs.
- Imported India tobacco has less than half the radiation content of
- that grown in the U.S.
- Kicking the nicotine habit is not easy, and nobody has the
- right to expect it of you. Often physical addictions are
- reinforced by emotional and psychological needs. Filling or coming
- to terms with those needs can give you the inspiration and added
- freedom to succeed.
- Most of all, inform yourself, even if the information is
- disturbing. You are a lot less likely to be taken in by tobacco
- advertising once you know the facts.
-
-
- Nicotine, the active ingredient in tobacco smoke, has long
- been known to be highly addictive. In fact, doctors and
- pharmacologists are not in consensus as to which is more addictive
- -- nicotine, or heroin. Physical addiction occurs when a chemical
- becomes essential for the body or metabolism to function. In other
- words, a substance is said to be physically addictive if extended
- use results in a build up of tolerance in the body to the extent
- that discontinuing use of the substance results in negative side
- effects. Called "withdrawal symptoms," these consequences can
- include anxiety, stress, trauma, depression and physical conditions
- such as shakes or nausea. It is to avoid these consequences that
- an addict will keep using his or her substance.
- In addition to being addictive, nicotine is also a toxin (i.e.
- lethal if ingested in sufficient quantities.) Nicotine has been
- shown to have a negative effect on the heart and circulatory
- systems, causing a constriction in veins and arteries which may
- lead to a stroke or heart attack. In fact, nicotine is so
- poisonous that smokers who ignore their doctor's advice and
- continue to smoke while using dermal nicotine patches have managed
- to overdose and die of heart seizure.
-
- Many people think smoking marijuana is just as harmful as
- smoking tobacco, but this is not true. Those who hold that
- marijuana is equivalent to tobacco are misinformed. Due to the
- efforts of various federal agencies to discourage use of
- marijuana in the 1970's the government, in a fit of "reefer
- madness," conducted several biased studies designed to return
- results that would equate marijuana smoking with tobacco smoking,
- or worse.
- For example the Berkeley carcinogenic tar studies of the
- late 1970's concluded that "marijuana is one-and-a-half times as
- carcinogenic as tobacco." This finding was based solely on the
- tar content of cannabis leaves compared to that of tobacco, and
- did not take radioactivity into consideration. (Cannabis tars do
- not contain radioactive materials.) In addition, it was not
- considered that:
- 1) Most marijuana smokers smoke the bud, not the leaf, of
- the plant. The bud contains only 33% as much tar as tobacco.
- 2) Marijuana smokers do not smoke anywhere near as much as
- tobacco smokers, due to the psychoactive effects of cannabis.
- 3) Not one case of lung cancer has ever been successfully
- linked to marijuana use.
- 4) Cannabis, unlike tobacco, does not cause any narrowing of
- the small air passageways in the lungs.
- In fact, marijuana has been shown to be an expectorant and
- actually dilates the air channels it comes in contact with. This
- is why many asthma sufferers look to marijuana to provide relief.
- Doctors have postulated that marijuana may, in this respect, be
- more effective than all of the prescription drugs on the market.
- Studies even show that due to marijuana's ability to clear
- the lungs of smog, pollutants, and cigarette smoke, it may
- actually reduce your risk of emphysema, bronchitis, and lung
- cancer. Smokers of cannabis have been shown to outlive non-
- smokers in some areas by up to two years. Medium to heavy
- tobacco smokers will live seven to ten years longer if they also
- smoke marijuana.
- Cannabis is also radically different from tobacco in that it
- does not contain nicotine and is not addictive. The psychoactive
- ingredient in marijuana, THC, has been accused of causing brain
- and genetic damage, but these studies have all been disproven.
- In fact, the DEA's own Administrative Law Judge Francis Young has
- declared that "marijuana in its natural form is far safer than
- many foods we commonly consume."
-
- The disturbing thing about all of this information is that
- the majority of Americans are as yet unaware of the radioactive
- risk in cigarettes. In fact, many professionals: doctors,
- scientists and health administrators, either have never heard of
- polonium 210 or consider it to be just another scare story.
- Why is this information so hard to come by? When the
- studies were first released in the late 70's, many magazines were
- unable to print articles because their main advertisers,
- cigarette companies, threatened to pull support if they published
- the facts. Although network news did pick up the story,
- virtually nothing came out in print. Those who heard were hard
- pressed to produce collaborating evidence, and were eventually
- convinced it was nothing to worry about.
- The power of the cigarette industry to suppress information
- goes far beyond magazines, however. A well financed tobacco
- lobby has been very active in the United States Congress for
- decades procuring subsidies and fighting laws and proposed
- research which could hurt the American tobacco industry. Tobacco
- interests practically own Senate and House seats, as many
- campaign contributions come from cigarette profits. Tobacco pay-
- offs also go to fund organizations such as the Partnership For A
- Drug Free America, which adopt a harsh anti-drug agenda yet seem
- to omit alcohol and tobacco (claiming they are harmless.)
- As an example, a 1984 law which was intended to require
- tobacco companies to release to the public a list of additives
- used in the manufacture of cigarettes was watered down to the
- extent that the list is now released only to the Department of
- Health and Human Services on the condition that it not be shown
- to anyone else. Companies have been known in the past to add
- chemicals to cigarettes for flavor, and, many assert, for their
- addictive properties. In Britain such chemicals have included
- acetone and turpentine, as well as an assortment of known
- carcinogens.
- Tobacco companies argue that revealing their 'secret
- ingredients' would hurt their competitiveness. In fact, when
- Canada passed legislation forcing additive lists to be released,
- one large company reformulated its recipe for its Canadian
- distribution; another took its product out of Canada entirely.
- Tobacco companies do not have the right to poison the
- public. Don't trust them. Get the information you need to make
- your own decisions, and restore government to the people.
-
- Another destructive aspect of the Drug War is the
- unreasonable measures taken as a result of "reefer madness."
- Because of the long standing anti-pot-smoking paranoia begun in
- the 1930's, many law enforcement agencies have taken it upon
- themselves to censor and limit the marijuana culture through
- whatever channels they can find. This includes the banning of
- various forms of drug "paraphernalia" (pipes, clips, rolling
- papers, etc.)
- Water pipes, or "bongs," are quite often the target of such
- efforts. Claiming that water pipes are constructed to allow
- marijuana smokers to inhale "dangerous" marijuana smoke deeper
- into their lungs, many states and towns have passed laws
- controlling the sale, manufacture, and possession of these items
- for "health" reasons.
- The sad fact is, water pipes have been shown to be extremely
- effective in removing harmful materials from smoke before it
- reaches the lungs. They also cool the smoke and prevent injury
- and irritation to lung passages. In effect, laws against water
- pipes hurt all smokers, cannabis and tobacco, by preventing the
- development of safer forms of consumption.

-
- To the Editor: During the 17 years since the Surgeon General's
- first report on smoking, intense research activity has been focused
- on the carcinogenic potential of the tar component of cigarette
- smoke. Only one definite chmical carcinogen -- benzopyrene --
-
- (typist note: He was later corrected on this "fact")
-
- has been found. Conspicuous because of its absence is research into
- the role of the radioactive component of cigarette smoke.
- The alpha emitters polonium-210 and lead-210 are highly con-
- centrated on tobacco trichomes and insoluble particles in cigarette
- smoke (1). The major source of the polonium is phosphate fertilizer,
- which is used in growing tobacco. The trichomes of the leaves con-
- centrate the polonium, which persists when tobacco is dried and
- processed.
- Levels of Po-210 were measured in cigarette smoke by Radford and
- Hunt (2) and in the bronchial epithelium of smokers and nonsmokers
- by Little et al. (3) After inhalation, ciliary action causes the insoluble
- radioactive particles to accumulate at the bifurcation of segmental
- bronchi, a common site of origin of bronchogenic carcinomas.
- In a person smoking 1 1/2 packs of cigarettes per day, the radia-
- tion dose to the bronchial epithelium in areas of bifurcation is 8000
- mrem per year -- the equivalent of the dose to the skin from 300
- x-ray films of the chest per year. This figure is comparable to total-
- body exposure to natural background radiation containing 80
- mrem per year in someone living in the Boston area.
- It is a common practive to assume that the exposure received
- from a radiation source is distributed throughout a tissue. In this
- way, a high level of exposure in a localized region -- e.g. bronchial
- epithelium -- is averaged out over the entire tissue mass, suggest-
- ing a low level of exposure. However, alpha particles have a range of
- only 40 um in the body. A cell nucleus of 5 to 6 um that is traversed
- by a single alpha particle receives a dose of 1000 rems. Thus, although
- the total tissue dose might be considered negligible, cells
- close to an alpha source receive high doses. The Po-210 alpha activity
- of cigarette smoke may be a very effective carcinogen if a multiple
- mutation mechanism is involved.
- Radford and Hunt have determined that 75 per cent of the alpha
- activity of cigarette smoke enters the ambient air and is unab-
- sorbed by the smoker, (2) making it available for deposit in the lungs
- of others. Little et al. have measured levels of Po-210 in the lungs of
- nonsmokers that may not be accounted for on the basis of natural
- exposure to this isotope.
- The detrimental effects of tobacco smoke have been considerably
- underestimated, making it less likely that chemical carcinogens
- alone are responsible for the observed incidence of tobacco-related
- carcinoma. Alpha emitters in cigarette smoke result in appreciable
- radiation exposure to the bronchial epithelium of smokers and
- probably secondhand smokers. Alpha radiation is a possible etio-
- logic factor in tobacco-related carcinoma, and it deserves further
- study.
