These carcinogens are absorbed through the mouth and may be why several types of cancer are linked to the use of smokeless tobacco. Smokeless tobacco products contain a variety of potentially harmful chemicals, including high levels of TSNAs. There are also other cancer-causing agents in smokeless tobacco, such as polonium-210 (a radioactive element) and other polycyclic aromatic hydrocarbons (PAHs). The main smokeless tobacco products in the United States are snuff and chewing tobacco, which are put into the mouth or nose but are not burned like cigarettes or cigars. To learn more, see Health Risks of Smoking Tobacco. This results in higher concentrations of nitrogen oxides, ammonia, carbon monoxide, and tar – all very harmful substances. When cigar tobacco is smoked, these compounds give off several tobacco-specific nitrosamines (TSNAs), some of the most potent cancer-causing substances known.Īlso, because the cigar wrapper is less porous than a cigarette wrapper, the tobacco doesn’t burn as completely. Is cigar smoke different?Ĭigar smoke has many of the same toxic and carcinogenic compounds as cigarette smoke, but some of them are present at different levels.īecause of the aging process used to make cigars, cigar tobacco has high concentrations of some nitrogen compounds (nitrates and nitrites). This may be another key factor in people who smoke getting lung cancer. These radioactive materials are given off in the smoke when tobacco is burned, which people who smoke take into their lungs as they inhale. 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. Radioactive materials are in the tobacco leaves used to make cigarettes and cigars. Most of the substances come from the burning tobacco leaves themselves, not from additives included in cigarettes (or other tobacco products). Many of these substances cause cancer. Some can cause heart disease, lung disease, or other serious health problems, too. Polycyclic aromatic hydrocarbons (PAHs).Radioactive elements, such as polonium-210 (see below).Nicotine (the addictive drug that produces the effects in the brain that people are looking for).
Some of the chemicals found in tobacco smoke include: These cancer-causing chemicals are referred to as carcinogens. Tobacco smoke is made up of thousands of chemicals, including at least 70 known to cause cancer. The smoke from these products is a complex mixture of chemicals produced by burning tobacco and its additives. Other substances are often added for flavor and to make smoking more pleasant. Tobacco smokeĬigarettes, cigars, and pipe tobacco are made from dried tobacco leaves. All types of tobacco products contain chemicals that can be harmful to your health.
