Cigarettes, cigars, and pipe tobacco are made from dried tobacco leaves. Other substances are added for flavor and to make smoking more pleasant. The smoke from these products is a complex mixture of chemicals produced by burning tobacco and its additives. Tobacco smoke is made up of thousands of chemicals, including at least 70 known to cause cancer. These cancer-causing chemicals are referred to as carcinogens. Many of these substances cause cancer. Some can cause heart disease, lung disease, or other serious health problems, too.
Most of the substances come from the burning tobacco leaves themselves, not from additives included in cigarettes or other tobacco products. Radioactive materials are in the tobacco leaves used to make cigarettes and cigars. These materials come from the fertilizer and soil used to grow the tobacco leaves, so the amount in tobacco depends on the soil the plants were grown in and the type of fertilizers used. These radioactive materials are given off in the smoke when tobacco is burned, which smokers take into their lungs as they inhale.
This may be another key factor in smokers getting lung cancer. Cigar smoke pretty much has the same toxic and carcinogenic compounds as cigarette smoke, but some of them are present at different levels. Because of the aging process used to make cigars, cigar tobacco has high concentrations of some nitrogen compounds nitrates and nitrites.
When the fermented cigar tobacco is smoked, these compounds give off several tobacco-specific nitrosamines TSNAs , some of the most potent cancer-causing substances known. This results in higher concentrations of nitrogen oxides, ammonia, carbon monoxide, and tar — all very harmful substances. Smokeless tobacco products include snuff and chewing tobacco that is put into the mouth or nose but is not burned like cigarettes or cigars. Still, smokeless products in the United States contain a variety of potentially harmful chemicals, including high levels of TSNAs.
There are also other cancer-causing agents in smokeless tobacco, such as benzo[a]pyrene and other polycyclic aromatic hydrocarbons PAHs. These carcinogens are absorbed through the mouth and may be why several types of cancer are linked to the use of smokeless tobacco. Like other forms of tobacco, smokeless tobacco also contains radioactive substances. It was first used in Sweden and Norway, but it is now available in the United States as well.
