Smoke-Free Rules and Secondhand Smoke Exposure in Homes and Vehicles Among US Adults, 2009–2010

Four out of five U.S. adults report having voluntary smoke-free rules in their homes and three out of four report having voluntary smoke-free rules in their vehicles, according to a study published in the journal Preventing Chronic Disease, a publication of the Centers for Disease Control and Prevention. The National Adult Tobacco Survey respondents were classified as having smoke-free rules if they never allow smoking inside their homes or vehicles. The study is the first to present estimates of smoke-free rules and secondhand smoke exposure in vehicles among U.S. adults. Despite the high prevalence of voluntary smoke-free rules in homes and vehicles, the study found that almost 11 million non-smoking adults continue to be exposed to secondhand smoke in their home, and almost 17 million non-smoking adults continue to be exposed to secondhand smoke in a vehicle. The study also contains state-by-state data showing that the highest prevalence of smoke-free rules in homes and vehicles occurred in many states with comprehensive smoke-free laws and longstanding tobacco control programs.

Additional study findings include:

Exposure to secondhand smoke causes heart disease and lung cancer in adult non-smokers. In children, secondhand smoke exposure causes more severe and frequent asthma attacks, acute respiratory infections, ear infections and sudden infant death syndrome (SIDS). Secondhand smoke exposure is responsible for an estimated 50,000 deaths each year in the United States. The Surgeon General has concluded there is no safe level of exposure to secondhand smoke, and that only 100 percent smoke-free policies can protect non-smokers from the dangers of secondhand smoke. Opening a window does not work, nor does any other ventilation system.
