What Stan does not reveal in his review article is that instead of estimating cessation rates among a cohort of smokers who made quit attempts using these products, the Vickerman study analyzed cessation rates of a large number of smokers who had previously tried to quit using e-cigarettes but failed, and then called a quitline because they had failed and wanted to try again. Then, they compared the quit rate among these smokers to that among smokers without such a history of a failed quit attempt using electronic cigarettes.

The rest of the story is that none of these studies examined quit rates among smokers who were trying to quit using e-cigarettes. None of these studies were in fact designed to examine the role of e-cigarettes in smoking cessation in the first place.

In other words, the anti-smoking movement is violating the first principle of public health practice by doing public health harm.

In fact, it could well be that flavored electronic cigarette use inhibits youth smoking by making it much less likely that a youth is going to enjoy his or her first experience with real tobacco cigarettes. The oral and respiratory tracts that are used to fruit or candy flavors are most likely not going to be able to tolerate or enjoy the harsh taste and sensation of a tobacco cigarette. For this reason, it is entirely conceivable that the use of electronic cigarettes might actually be a deterrent to cigarette smoking.
