4. Overall motivation to quit has increased since the dramatic rise in e-cigarette use.

Contrary to the assertion of the authors of this paper, simply being aware that the information one provides to Facebook may be used for research purposes does not constitute informed consent. The fact that users agreed to a Data Use Policy which notes that information may be used for research purposes does not, as the authors state, "[constitute] informed consent for this research."

While research is clearly needed to understand the trajectory of youth use of electronic cigarettes, the Monitoring the Future survey data do not support the CDC's conclusion that these products are serving as a gateway to youth smoking.

According to a issued by Columbia University Medical Center, a team of researchers from Columbia University have concluded that electronic cigarettes may serve as a gateway not only to cigarette smoking, but also to illicit drug use and addiction, such as cocaine addiction.

In a recent in Forbes magazine, Jacob Sullum reviews some of the evidence which demonstrates that many former smokers have quit smoking successfully using electronic cigarettes as a cessation aid. Sullum writes:

With that said, I can’t completely blame Senator Blumenthalbecause the CDC has been disseminating the false assertion that its recentsurvey demonstrated that e-cigarettes are a gateway to smoking addiction. So itappears that the lie originated with the CDC and then was adopted by SenatorBlumenthal. He may not be deserving of all of the blame here. The CDC must bearthe responsibility for originating this lie.

Suppose that there are 1000 e-cigarette users who enter the cancer center with a diagnosis of cancer. Of these, an amazing 900 were able to quit smoking. However, 100 were very resistant smokers and could not quit smoking, even with e-cigarettes. Note that it would be these 100 resistant smokers who would be enrolled in the study. The 900 ex-smokers who quit using e-cigarettes would not be eligible for the study, because they no longer smoke.
