The amount of Americans who are exposed to secondhand smoke has decreased by nearly half in the past 12 years, reports the CDC.
The decline— from 53 percent in 2000 to 25 percent in 2012—is due to many cities and states banning cigarettes in public areas, which has also led smoking to become increasingly less socially accepted.
But secondhand smoke is not entirely a thing of the past—1 in 4 nonsmokers (or 58 million Americans) are still being exposed to these harmful chemicals.
"Children are often exposed to smoke in their homes, and the report speculated that the sluggish decline in exposure of children might have to do with the fact that the fall in the adult smoking rate has slowed," reports The New York Times.
