In 2011, a mere 1.5% of American high school students reported using electronic cigarettes, according to research from the US Centers for Disease Control. By 2014, that proportion had jumped nearly nine-fold, to an estimated 13.4%. Smoking among high schoolers, on the other hand, saw a fairly drastic decline over the same time period, dropping from 15.8% to 9.2%. All in all, those trends should be seen as a big win, proponents of vaping say.
This infographic details those trends and the future of E-Cigs.
