2. There is no reason to believe this argument is true in the first place. The percentage of smokers who quit on their own is dismally low. Moreover, the very reason why smokers are trying electronic cigarettes is because they have failed to quit smoking with existing therapies. It is ludicrous to expect that someone who has no confidence in quitting using a traditional methods is suddenly going to quit. In fact, the evidence overwhelmingly shows that without self-efficacy, most smokers are bound to fail. So we are talking about a population of smokers who are not going to quit smoking anyway. Electronic cigarettes are their last best hope. Sure, e-cigarettes are not for everyone and many will fail. But it is simply not true that those who fail are people who would have quit smoking if only they hadn't tried electronic cigarettes.

"Only 1.8% of children are regular users; 90% of regular or occasional users are young people who are already smokers or ex-smokers; 91% of young people have not tried an electronic cigarette even once; and this is despite the fact that over 80% of young people are now aware of e-cigarettes (up from under 70% in 2013)."

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.

In a press release issued Monday by 13 members of Congress, a group of politicians claimed that there is "more" evidence that electronic cigarettes are a gateway to smoking.
