Advertising for e-cigarettes has exploded in recent years, and many of those ads are targeting youth. According to a report in Pediatrics, teens’ exposure to e-cig advertisements shot up 256 percent between 2011 and 2013. Exposure of young adults (classified as those between the ages of 18 and 24) has risen 321 percent during the same timeframe.

About three-quarters of those ads were found on television, particularly on networks that (according to the study) targets younger viewers, including AMC, Country Music Television, Comedy Central, TV Land and VH1. (Time)
