Invalidity of an Oft-Cited Estimate of the Relative Harms of Electronic Cigarettes.

An editorial on the issue of harm from electronic cigarettes is presented. It mentions the original report from 2013 that concluded that electronic cigarettes were much less harmful than regular cigarettes, the changes in e-cigarettes that expose users to greater levels of nicotine, and the presentation of evidence that e-cigarettes cause harm in a number of ways, thus invalidating the original statistics.
