For kids, the home is the place where they are most exposed to secondhand smoke. The home is also a major location of secondhand smoke exposure for adults.

Children who live in homes where smoking is allowed have higher levels of exposure to secondhand smoke than children who live in homes where smoking is not allowed. The greater the number of cigarettes smoked in the home, the greater children’s exposure to secondhand smoke.

According to the office of the US Surgeon General, although secondhand smoke exposure among children has declined over the past 15 years, children remain more heavily exposed to secondhand smoke than adults. The number of homes that report that smoking isn't allowed in the home has increased from 71.1 percent in 2000 to 85 percent in 2009, according to Tobacco Free Nebraska.

Almost 60 percent of U.S. children aged 3-11 years—or almost 22 million children—are exposed to secondhand smoke, according to the office of the US Surgeon General.
