Roughly 6.5 million U.S.

Roughly 6.5 million U.S. high school students have been exposed to secondhand smoke from e-cigarettes in the past 30 days, according to the Centers for Disease Control and Prevention. The finding is particularly alarming because the U.S. surgeon general reports that exposure of e-cigarettes’ nicotine could “dangerously” affect adolescent brain development. E-cigarette use among high school students jumped 900% between 2011-2015, becoming a “growing concern.” (Washington Post)
