The rest of the story is that Dr. Frieden continues to fabricate scientific evidence in an apparent effort to demonize electronic cigarettes. I have already reported how he that he purported to demonstrate that electronic cigarettes are a gateway to a lifetime addiction to smoking cigarettes. Here, he apparently makes up scientific evidence that large numbers of ex-smokers are returning to nicotine use by taking up vaping. While I follow the electronic cigarette literature extremely closely, I am aware of no studies which have shown that large numbers of ex-smokers are taking up vaping. In contrast, there is much evidence that large numbers of vapers are quitting smoking, and thus becoming ex-smokers.

A scientific review on electronic cigarettes was published by Stan Glantz and colleagues this week in the journal Circulation.

In the study, investigators examined measures of acute heart function using echocardiography among 36 smokers and 40 vapers, before and after using either a cigarette or e-cigarette. The researchers found that cigarette smoking adversely affected acute heart function. Electronic cigarette use had no effect on any of the measures examined.
