In other words, the blatant flaw in this study is that it enrolled smokers who had already made quit attempts using e-cigarettes in the past. By definition, this resulted in a sample of smokers who were more resistant to quitting. One would expect to find lower quitting rates among this population of e-cigarette users.

Senator Blumenthal has clearly his position: "'I think flavors ought to be banned,' Blumenthal told U.S. News. It's 'completely disingenuous' to say adults are the primary users of popular flavor options, he said."

Moreover, what scientific evidence is the FDA looking for in order to approve a simple claim that electronic cigarettes are safer than tobacco cigarettes? If the overwhelming current evidence is not sufficient, then no evidence will ever be sufficient because there is no further research that is necessary in order to draw this conclusion. It doesn't take a rocket scientist to figure out that a product which burns tobacco and produces tobacco smoke with more than 10,000 chemicals including more than 60 carcinogens and causes more than 400,000 deaths per year is more harmful than a product which merely heats and aerosolizes nicotine from a solution of propylene glycol.
