In my opinion, rather than being an objective scientific review of the literature, this article is little more than a hatchet job on e-cigarettes. The authors clearly have reached a pre-determined conclusion that e-cigarettes are not helpful in smoking cessation and they stretch science beyond recognition in trying to get the published scientific evidence to support this conclusion.

These studies are simply ignored by the Surgeon General's report and by my colleagues who have attacked me. It would be one thing if there were no evidence for my opinions, but it's hardly appropriate to attack an individual for expressing an opinion that is backed up by scientific studies.
