"CDC's Environmental Health Laboratory houses the Tobacco Laboratory, which investigates both individual and population exposures to the chemicals in tobacco products. The Laboratory is unique because it measures toxic and addictive substances in tobacco products, in smoke and other emissions, and in people who use tobacco products or are exposed to secondhand smoke. No other laboratory in the federal government has these capabilities. Tobacco smoke contains more than 4,000 chemical components, and at least 250 of these chemicals are harmful to human health. By looking at all aspects of tobacco use and exposure, scientists in the Tobacco Laboratory are able to obtain a more accurate understanding of how smokers, non-smokers (through secondhand smoke), and smokeless tobacco users are exposed to harmful chemicals." - p.
