There is no safe levels of exposure to secondhand smoke. Secondhand smoke is a mixture of two forms of smoke that come from burning tobacco: sidestream smoke (smoke that comes from the end of a lighted cigarette, pipe, or cigar) and mainstream smoke (smoke that is exhaled by a smoker). The sidestream smoke has higher concentrations of cancer-causing agents (carcinogens) than the mainstream smoke. And, it contains smaller particles than mainstream smoke, which make their way into the body's cells more easily. When non-smokers are exposed to secondhand smoke it is called involuntary smoking or passive smoking. Non-smokers who breathe in secondhand smoke take in nicotine and other toxic chemicals just like smokers do.
