Secondhand smoke is a combination of the smoke in the air from a burning cigarette, cigar, or pipe and the smoke exhaled by a person who is smoking. Smoke-filled rooms have up to six times the air pollution of a busy highway. Secondhand smoke has been designated as a human cancer-causing agent by the U.S. EPA, the National Toxicology Program, and the International Agency for Research on Cancer. It’s the number one source of indoor air pollution, and it poses a health threat to most Coloradoans.

Some parents don’t fully understand how harmful secondhand smoke is for their kids, but most of them do understand that it is dangerous. That’s why most parents—including parents who smoke—try to protect their kids from secondhand smoke. Unfortunately, sometimes common myths about secondhand smoke lead some parents to think they’re protecting their kids when they’re really not.

Protecting your kids from secondhand smoke takes only One Step: Always step outside the home and the car before smoking.
