So when Cigavette claims they have “the most advanced nicotine vapor system available, using a state of the art microprocessor and patented smart chip technology”, let’s just say I’m always a little skeptical…

From a public health perspective, the effectiveness of e-cigarettes for smoking cessation must be assessed by examining how effective the product is for smokers who are trying to quit. When you do that properly, this initial evidence suggests that you find out e-cigarettes are a viable smoking cessation aid for a subset of smokers.

"It is not known how much nicotine or other potentially harmful chemicals are inhaled by users, nor is it known whether e-cigarette use may lead to use of other tobacco products. Neither are the benefits of using e-cigarettes over traditional products known."

It should be clear to readers that this study was poorly designed toinvestigate the efficacy of electronic cigarettes. The study systematicallysampled a group of quitline callers who were unsuccessful using electroniccigarettes. These people tried and failed using electronic cigarettes. How dowe know they failed? Because they wouldn’t have had to call the quitline ifthey weren’t still smoking. This is clearly a harder core group of smokers andit is no surprise that their cessation rates were lower after 6-months than thecomparison group. The study tells us nothing about the effectiveness ofelectronic cigarettes, other than that they do not work for everyone. In fact, this research is biased in favor of not finding aneffect of electronic cigarettes on smoking cessation.
