Secondhand Smoke

An estimated 21% of all adults (45 million people) smoke cigarettes in the United States.1 Secondhand smoke, also known as environmental tobacco smoke, is a complex mixture of gases and particles that include smoke from the burning cigarette, cigar, or pipe tip (sidestream smoke), and exhaled mainstream smoke. Secondhand smoke contains at least 250 known toxic chemicals, including more than 50 that can cause cancer.2 Secondhand smoke causes heart disease and lung cancer in nonsmoking adults and a number of health conditions, including sudden infant death syndrome (SIDS) and respiratory infections, in children.3

More than 126 million nonsmoking Americans continue to be exposed to secondhand smoke in homes, vehicles, workplaces, and public places. Most exposure to tobacco smoke occurs in homes and workplaces. Almost 60% of U.S. children aged 3–11 years—or almost 22 million children—are exposed to secondhand smoke.3

For more information on Secondhand Smoke, please see the Secondhand Smoke Fact Sheet.

 

Number of U.S. adult smokers: 45 million; number exposed to second hand smoke: 126 million; number U.S. children age 3 to 11 exposed to second hand smoke: 22 million
