Secondhand SmokeSecondhand Smoke (SHS), also called Involuntary Smoking, Passive Smoking, or Environmental Tobacco Smoke (ETS), is a combination of tobacco smoke exhaled by a smoking person as well as the smoke produced by the burning end of the cigarette, cigar or tobacco pipe.

  • SHS contains at least 250 toxic chemicals, including arsenic, formaldehyde, hydrogen cyanide, and radioactive elements. More than 50 of these toxic chemicals can cause cancer.

  • A person standing 20 inches from a burning cigarette may inhale 10 times more of these toxic chemicals than the person smoking the cigarette.

  • No level of SHS exposure is risk-free.

  • Nearly half of the people in the U.S. have biological evidence of SHS exposure.

  • SHS is the number one source of indoor air pollution.

  • Most exposure to tobacco smoke occurs in homes and workplaces.

  • Spending one hour in a smoke-filled room is equal to smoking one cigarette.


If you are exposed to SHS, consider taking one of the following steps:

  • Ask your family member, friend, or coworker to quit smoking

  • Ask your family member, friend, or coworker to only smoke outside 

  • Ask you employer to ban smoking in your workplace
