The nation's top doctor is sounding the alarm on e-cigarettes, especially when used by teens and young adults.
"These products are now the most commonly used form of tobacco among youth in the United States, surpassing conventional tobacco products, including cigarettes, cigars, chewing tobacco and hookahs," wrote Dr. Vivek H. Murthy, the US Surgeon General, in a new report released Thursday. In fact, use of e-cigarettes among high school students increased by 900% from 2011 to 2015, according to the report.
