Exposure to secondhand smoke is unhealthy, even if you are outdoors. Recent changes in laws, policies and practices have concentrated on indoor exposure. But these alterations have not eliminated exposure to secondhand smoke. This short video (1:54 minutes) discusses an air quality study by Stanford University conducted at park benches, sidewalk cafes and other public places.
In fact, a study released this month, finds exposure to outdoor secondhand tobacco smoke from ONE lit cigarette that is 29.5 feet away.
