What is secondhand smoke?

Secondhand smoke refers to tobacco smoke that is passively breathed in by people in the vicinity of a person who is smoking. Terms that have been used to refer to secondhand smoke are passive smoking, involuntary smoking, or environmental tobacco smoke (ETS). Secondhand smoke is a mixture of the smoke from the tobacco product itself (termed sidestream smoke) and exhaled smoke from the smoker (known as mainstream smoke).

When a nonsmoker inhales secondhand smoke, he or she is exposed to the same toxins and chemicals, including nicotine, as the smoker.

Exposure of children to secondhand smoke also increases their health risks; and children are especially vulnerable to the effects of environmental tobacco smoke. Even children who do not live with smokers may be at risk for adverse effects of secondhand smoke. Chemicals from tobacco smoke inhaled by a nursing mother are also known to reach breast milk.
