What are the health risks of secondhand smoke?

Secondhand smoke carries many health risks. At least 250 harmful chemicals have been identified in secondhand smoke, including at least 50 carcinogens (chemicals that are known to cause cancer). Just some of the dangerous chemicals present in secondhand smoke include vinyl chloride, cadmium, benzene, arsenic, and ethylene oxide.

Secondhand smoke is known to cause cancer. It has been classified as a "known human carcinogen" by the U.S. Environmental Protection Agency (EPA). It is also associated with cardiovascular and respiratory diseases as well as other serious health conditions; several are listed below.

Lung cancer and secondhand smoke

Passive smoking is an established risk factor for the development of lung cancer. Research has shown that nonsmokers who reside with a smoker have a 20% to 30% increase in risk for developing lung cancer when compared with nonsmokers who do not reside with a smoker. An estimated 3,400 lung cancer deaths that occur each year in the U.S. are attributable to passive smoking.

Cardiovascular disease and secondhand smoke

Like cigarette smoking itself, secondhand smoke is a significant risk factor for the development of cardiovascular disease and heart attack. An estimated 46,000 deaths from heart disease in non-smokers who live with smokers occur every year in the U.S.
