An estimated 88 million nonsmoking Americans, including 54% of children aged 3–11 years, are exposed to secondhand smoke.
Nonsmokers who are exposed to secondhand smoke at home or work increase their lung cancer risk by 20–30%.
Nonsmokers who are exposed to secondhand smoke at home or work increase their heart disease risk by 25–30%.
Each year, primarily because of exposure to secondhand smoke, an estimated 3,000 nonsmoking Americans die of lung cancer, and more than 46,000 die of heart disease.
Children are at particular risk for exposure to secondhand smoke: 53.6% of young children (aged 3–11 years) were exposed to secondhand smoke in 2007–2008.
While only 5.4% of adult nonsmokers in the United States lived with someone who smoked inside their home, 18.2% of children (aged 3–11 years) lived with someone who smoked inside their home in 2007–2008.
Babies and children who breathe secondhand smoke are sick more often with bronchitis, pneumonia, and ear infections.
In children, secondhand smoke causes:
More frequent and severe asthma attacks
Respiratory issues, including coughing, sneezing, and shortness of breath
Respiratory infections, including bronchitis and pneumonia
An increased risk of sudden infant death syndrome (SIDS)
In children aged 18 months and younger in the United States, secondhand smoke exposure is responsible for:
150,000–300,000 new cases of bronchitis and pneumonia annually
Approximately 7,500–15,000 hospitalizations annually
