E-cigarettes May Affect Teen Tobacco Use

This article describes a study by researchers at the University of Southern California that analyzed e-cigarette use among high school students and its relationship with trying smoking tobacco products. Researchers analyzed data from more than 2,500 students who reported they had not smoked any tobacco products at the start of ninth grade. After six months, 31% of those who had used e-cigarettes started smoking tobacco, compared to 8% of those who had never used e-cigarettes. Over the next six months, 25% of e-cigarette users reported they had smoked tobacco in the past six months, compared to 9% of those who had not used e-cigarettes.
