Secondhand Smoke & Children's Health

Secondhand smoke is also known as environmental tobacco smoke (ETS), passive smoke, or involuntary smoke. It is released into the air when tobacco products burn or when smokers exhale. Cigarettes, cigars, and pipes all can produce toxic secondhand smoke.

This pamphlet summarizes some of the findings from a recent comprehensive review of hundreds of studies of secondhand smoke by the California EPA’s Office of Environmental Health Hazard Assessment.
