Today, no-smoking policies have become so widespread that we hardly think twice when we’re enjoying a meal at a restaurant in a smoke-free environment.

Millions of Americans benefit from these policies, which have significantly reduced exposure to secondhand tobacco smoke in public spaces. A few recent studies show us that further reducing exposure can save the U.S. $10 billion annually in healthcare costs and wages lost to sick leave.

Secondhand smoke, passive smoking, side stream smoke, or environmental tobacco smoke (ETS) all refer to the same thing: the smoke exhaled by a smoker or given off by the burning end of a cigarette, pipe, or cigar.  Whatever you call it, thanks to EPA scientists we know that exposure to such smoke threatens our health—and is especially risky for those most vulnerable like older Americans and our kids.

Through their research, our scientists released a landmark health assessment in 1992, The Respiratory Health Effects of Passive Smoking: Lung Cancer and Other Disorders, that found that secondhand smoke leads to serious health complications, and even premature death. The assessment concluded that infants and young children were especially sensitive to secondhand smoke exposure, leading to more respiratory infections like bronchitis and pneumonia, harming lower lung function, and worsening symptoms of asthma.
