And exposure to these ads has young adults who try to avoid the adverse health effects of e-cigarettes in a "Wild West" of sorts.
"It's the Wild West out there when it comes to e-cigarette advertising," Tom Frieden, director of the Centers for Disease Control and Prevention, told The Washington Post. "It's no coincidence that as the advertising has skyrocketed, the use of e-cigarettes has skyrocketed."
The report also came out at a time when teens are using e-cigarettes — or "vaping" — more than ever.
"E-cigarette use tripled among U.S. teenagers in 2014, and for the first time, more high-school students puffed on the devices — 13.4 percent — than traditional smokes — 9.2 percent," according to the Journal.
"In 2011, advertisers spent $6.4 million on e-cig advertisements in newspapers, magazines, television, and online," Yahoo Health's report read. "By 2013, that figure topped $60 million, according to AdAge. And in 2014, according to a CDC statement, advertisers spent $115 million promoting e-cigs."
Many researchers believe e-cigarettes prove less harmful than smokes; however, Frieden told Reuters that use of e-cigarettes in young people could lead to brain damage, addiction — and also higher risk of smoking regular cigarettes.
E-cigarette proponents argue the devices are a "stop-smoking tool," Collins' piece indicated.
But experts counter there's little research out there to back that up, Collins wrote.
Regardless of the risks or benefits, e-cigarette companies are "getting to (kids) early, long before they become teenagers," Matthew Myers, president of the Campaign for Tobacco-Free Kids, told the Post.
"It was the case with cigarettes 25 years ago," the Post quoted Myers as saying. "They are using the same themes and the same images [as tobacco]. But the penetration in the modern media era is as strong as anything we've ever seen."
