Big drop reported in vaping by US teenagers
NEW YORK Vaping rates among U.S. teenagers fell dramatically this year, according to a federal report released Wednesday. That marks a dramatic decline from a similar survey last year that found about 28% of high school students and 11% of middle school students recently vaped. The Centers for Disease Control and Prevention conducts the national survey of more than 20,000 middle and high school students. It asks students if they had used any vaping or traditional tobacco products in the previous month. CDC officials gradually focused their investigation on black market THC cartridges, and on a chemical compound called vitamin E acetate that had been added to illicit THC vaping liquids.
