Secondhand smoke contains over 7,000 chemicals, hundreds of which are toxic and approximately 70 of which are known to cause cancer.1 There is no safe level of exposure to secondhand smoke, and ventilation and air purifiers cannot completely control or eliminate it.

Babies are more likely to have weaker lungs and die of Sudden Infant Death Syndrome (SIDS) if they are around secondhand smoke. Children are more likely to develop lung problems, more frequent coughing and wheezing, ear infections and asthma.1,2Spouses and other adults also suffer when breathing in secondhand smoke. Nonsmokers who breath secondhand smoke are more likely to develop heart disease, lung cancer, and stroke.1,2It is estimated that secondhand smoke caused nearly 34,000 heart disease deaths each year during 2005-2009 among adult nonsmokers in the United States.1
