Feb

There is no risk-free level of exposure to secondhand smoke.

  • Secondhand smoke causes numerous health problems in infants and children, including more frequent and severe asthma attacks, respiratory infections, ear infections, and sudden infant death syndrome (SIDS).
  • Smoking during pregnancy results in more than 1,000 infant deaths annually.
  • Some of the health conditions caused by secondhand smoke in adults include coronary heart disease, stroke, and lung cancer.

Secondhand smoke is a mixture of the smoke that comes from the burning end of a cigarette, cigar, or pipe, and the smoke breathed out by the smoker. It contains more than 7,000 chemicals. Hundreds of those chemicals are toxic and about 70 can cause cancer.

There is no safe amount of secondhand smoke. Even low levels of it can be harmful. The only way to fully protect nonsmokers from secondhand smoke is not to allow smoking indoors. Click on the link below for an excellent list of resources related to secondhand smoke.
