According to the CDC, “Secondhand smoke exposure contributes to approximately 41,000 deaths among nonsmoking adults and 400 deaths in infants each year. Secondhand smoke causes stroke, lung cancer, and coronary heart disease in adults. Children who are exposed to secondhand smoke are at increased risk for sudden infant death syndrome, acute respiratory infections, middle ear disease, more severe asthma, respiratory symptoms, and slowed lung growth.”

About 4 out of 10 U.S. children aged 3–11 years (40.6%) are exposed to secondhand smoke, and the main place where children are exposed is in the home.

Smokefree homes and cars are vital to protect children!
