A new report shows that millions of people are still affected by secondhand smoke.
This comes after there was a decline of secondhand smoke exposure of over 70 percent from 1988-2014. The progress has stalled over the last couple years.
According to the CDC, approximately 58 million nonsmokers are exposed to secondhand smoke. Officials say the ones who are most at risk are children, and those living in poverty. 27 states and Washington D.C. have comprehensive smoke-free laws. Enforcement of such laws has slowed in recent years.
Some of the possible health problems in adults include increased risk of lung cancer, stroke and heart disease. Kids face an increased risk of ear infections, more frequent and severe asthma attacks and sudden infant death syndrome.
