Toxic Chemicals in Tobacco Products
Cigarette smoking is a major cause of lung cancer, the leading cause of
cancer death in both men and women in the United States. Worldwide, lung
cancer kills over one million people each year2. Tobacco smoke
contains over 60 carcinogens3. These chemicals
represent approximately 7 chemical classes (polycyclic aromatic
hydrocarbons, arenes, N-nitrosamines, aromatic and heterocyclic
aromatic amines, aldehydes, organic compounds, and inorganic compounds).
The 2000 Surgeon
General's Report has concluded that smokers receive very little information
regarding chemical constituents when they purchase a tobacco product.1

tobacco or tobacco smoke, plus the chemical levels in popular tobacco products.
