Lung cancer and secondhand smoke
Passive smoking is an established risk factor for the development of lung cancer. Research has shown that nonsmokers who reside with a smoker have a 20% to 30% increase in risk for developing lung cancer when compared with nonsmokers who do not reside with a smoker. An estimated 3,400 lung cancer deaths that occur each year in the U.S. are attributable to passive smoking.
Cardiovascular disease and secondhand smoke
Like cigarette smoking itself, secondhand smoke is a significant risk factor for the development of cardiovascular disease and heart attack. An estimated 46,000 deaths from heart disease in non-smokers who live with smokers occur every year in the U.S.
Other lung diseases and secondhand smoke
Coughing, chest congestion, and decreased lung function can also occur in those exposed to passive smoke. Babies exposed to secondhand smoke can also develop serious respiratory infections. In the U.S., passive smoking is believed to cause 150,000 to 300,000 lung infections (such as pneumonia and bronchitis) in children younger than 18 months of age each year.
Secondhand smoke and other effects on children
In addition to the risk of pneumonia and respiratory infections in babies exposed to secondhand smoke (see above), passive smoke is known to increase the severity of asthma in children with this condition. About 750,000 middle ear infections in children are also estimated to occur each year as a result of exposure to secondhand smoke. Babies who are exposed to secondhand smoke are at an increased risk for sudden infant death syndrome (SIDS).
