E-cigarettes are now the most commonly used tobacco product among kids, and the health effects can be just as bad as traditional cigarettes, according to a new report from the surgeon general.

The report sought to point out to parents the serious problems with e-cigarettes and the growing use of e-cigarettes among kids. The report mirrors past missives from surgeons general that have addressed the dangers of cigarettes and tobacco products, including a landmark report in 1964 that linked tobacco use to lung cancer and heart disease.
