The main difference between this study and those touted by Glantz as showing that e-cigarettes are ineffective is that unlike Glantz's cited studies, this one actually examines cessation rates among smokers who reported using e-cigarettes for smoking cessation. In other words, Brown et al. included smokers who reported having used e-cigarettes with the intention to quit smoking. In the studies cited by Glantz, smoking cessation rates for all e-cigarette users were examined, even if a smoker just tried a puff of an electronic cigarette to see what all the hype is about.

With this disregard for the basic principles of science, the FDA is undermining literally decades of public education about the severe hazards of cigarette smoking. The FDA is negating the benefits we have accrued from the tobacco companies halting their own undermining of the public's appreciation of smoking's hazards because the agency is now doing that work for the tobacco companies.

A recent from the UK involved a survey of 12,171 adults in February and March of this year. The survey found that 4.7% of ex-smokers were regularly using electronic cigarettes. Among these ex-smokers, 71% reported that they were using e-cigarettes to try to quit smoking and 48% reported that they were using e-cigarettes to try to keep off tobacco products. These data suggest that the overwhelming majority of ex-smokers using e-cigarettes are people who smoked and then quit smoking because of these products, rather than ex-smokers who returned to nicotine use via e-cigarettes.

In an published today in the Wall Street Journal, I highlight the fact that many legislators and health organizations have demonized electronic cigarettes, largely on the basis of the erroneous conclusion that there is scientific evidence demonstrating that these products are a gateway to cigarette smoking among youth. The piece points out that there actually is no such scientific evidence and in fact, it presents evidence to the contrary.

They write: "What’s even more troubling is that these products serve as a gateway to traditional tobacco products. A recent JAMA Pediatrics study found that middle and high-school students who used e-cigarettes were more likely to smoke traditional cigarettes and less likely to quit smoking." In support of this statement, they cite the Glantz and Dutra cross-sectional study of e-cigarette use and smoking among youth.
