A statement from the Campaign for Tobacco-Free Kids indicates that the percentage of Americans exposed to secondhand smoke has decreased since 1999 but non-smokers are still exposed.

The percentage of Americans exposed to secondhand smoke has fallen by more tthan half since 1999, but one in four non-smokers – 58 million people altogether – was still exposed in 2011-2012, according to a new report issued today by the Centers for Disease Control and Prevention (CDC). It is especially troubling that children have the highest levels of exposure, with 40.6 percent of children aged 3-11 and 67.9 percent of African-American children in that age group still exposed to secondhand smoke. While the sharp decline in exposure to secondhand smoke is great news, it is unacceptable that 58 million Americans, including so many children, are still exposed to this serious and entirely preventable health threat.
