E-cigarette marketing has become so ubiquitous, reports the Washington Post, that it now reaches more than two-thirds of U.S. middle and high school students, according to a new US Centers for Disease Control report — a development that some public health officials argue is prompting more teens to use the devices and threatening decades of progress in combating youth tobacco use.

More than 18 million (7 in 10) US middle and high school youth were exposed to e-cigarette ads in 2014.
More than 1 in 2 middle and high school youth were exposed to e-cigarette ads in retail stores.
Nearly 2 in 5 middle and high school youth saw e-cigarette ads online.
