So not only are these researchers lying by making false extrapolations, they are lying even in the assumptions they are making prior to making those extrapolations. Worst of all, they are trying to make determinations of risk based on only one small slice of the total information that is necessary to judge the relative safety of electronic cigarettes compared to tobacco cigarettes.

The article reports the results of a cross-sectional sample of adolescents interviewed in 2011 and 2012 in the National Youth Tobacco Survey. Youths were asked to report their smoking status as well as their e-cigarette use, both any use and current use (at least once in the past month).

It is clear from the overall evidence that electronic cigarettes are not as risky as tobacco cigarettes in terms of acute effects on lung function. On this issue, Dr. Glantz's comment is simply wrong.
