Based on these most recent data from the UK, it appears that there just is not evidence to support the wild contentions that anti-smoking groups, advocates, and health agencies like the CDC and World Health Organization are disseminating to the public. Contrary to what Stan Glantz is telling the press, there simply is no evidence that the use of electronic cigarettes is undermining smoking cessation or impeding the decline in smoking prevalence. Nor is there evidence that electronic cigarettes are causing nonsmokers or ex-smokers to return to cigarette smoking. Moreover, there is no evidence that dual use is decreasing the motivation of smokers to quit or precluding these smokers from reaping any health benefits.

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.

This is why I find it so troubling that some major voices in the e-cigarette community are arguing that RCTs should not be conducted and only survey studies are of value.

I'm sad to say that this is complete garbage.

The truth is that this paper provides no evidence whatsoever that e-cigarette use is a gateway to smoking. Instead, it is entirely possible - and quite likely - that youths who use e-cigarettes are more likely to be heavier and more resistant smokers.
