Maryjane 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 tobacco, smoke, marijuana, smokers, been, 210, cancer, polonium, lung, lungs, studies, radioactive, nicotine, fact, cigarette, smoking, shown, cannabis, years, risk, lead, companies, addictive, pipes, long, information, addition, water, tar, released, radioactivity, rad, law, due, cigarettes
