Today, the FDA launched its first e-cigarette prevention TV ads. Part of "The Real Cost" campaign, they're meant to educate teens on the dangers of e-cigarette use. The ads will target nearly 10.7 million teens, aged 12 to 17, who have used e-cigarettes or are open to trying them. The short clips feature street magician Julius Dein, who turns a vape pen into a cigarette before onlookers. The trick is supposed to highlight the fact that teens who vape are more likely to start smoking cigarettes.
