It is worth noting that the conclusions which Dr. Glantz is disseminating are destructive because they undermine decades of public education about the severe hazards of smoking. If the public thinks that smoking is only as risky as vaping, then it is likely that many smokers will decide to continue smoking rather than quitting using electronic cigarettes. And many ex-smokers who have quit with electronic cigarettes may return to smoking, thinking that they might as well since they are not getting any definite health benefit from having made the switch.

I am not going to comment on taste or throat hit as this isn’t the topic of discussion and thus I’ll also leave the brand and name of the E-Juice anonymous as well. My biggest complaint about the E-Juice was the lack of labeling of how much caffeine was in the bottle. The only thing the bottle said was “with caffeine.” Like nicotine, caffeine is a stimulant and in large doses could potentially be fatal. Knowing how much is in the bottle is crucial for users.

Ironically, Stan Glantz criticized the study specifically because it examined the effect of electronic cigarettes on quitting among smokers who desired to quit. According to an in the New York Times: "Stanton A. Glantz, a professor of medicine at the University of California, San Francisco, said the study’s limitation was that it tried to measure the effect of e-cigarette use only among smokers who were trying hard to quit, not all smokers."

The above argument is convenient for advocates who want to suppress "negative" or "unfavorable" findings by discouraging RCTs - which they believe will "underestimate" the effectiveness of e-cigarettes for smoking cessation and encouraging survey studies - which they believe will show the effects of vapor products in all their possible glory. However, the argument carries with it a lack of scientific validity.
