The study concluded that: "e-cigarettes generate smaller changes in lung function but similar nicotinergic impact to tobacco cigarettes."

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.

For years, we in tobacco control have attacked tobacco industry-funded scientists or researchers who consulted for tobacco companies for not disclosing their conflicts of interest. It it therefore quite unfortunate, and ironic, that tobacco control researchers do not appear to take their own conflicts of interest seriously and that they, too, are hiding these conflicts from the public.

The bottom line: it appears that the use of electronic cigarettes has tremendous health benefits not only for those who quit smoking, but also for those who become dual users. While it may take longer for these individuals to eventually get off of nicotine altogether, it appears that the switch to e-cigarettes yields a much lower level of nicotine addiction, making it easier, not harder, to subsequently cease using nicotine if they so desire.

A large proportion of the 88 smokers who had tried an e-cigarette may have simply been trying these products to see what they are like. It is plausible, in fact probable, that many of these 88 smokers were not actually interested in quitting or trying to quit with electronic cigarettes. These products have become very popular and have gained widespread media attention and it is entirely possible that many of these smokers simply wanted to see what the big fuss is all about.
