2 million US teens are vaping marijuana
A school-based survey shows nearly 1 in 11 U.S. students have used marijuana in electronic cigarettes, heightening health concerns about the new popularity of vaping among teens.
E-cigarettes typically contain nicotine, but many of the battery-powered devices can vaporize other substances, including marijuana. Results published Monday mean 2.1 million middle and high school students have used them to get high.
