"This is currently not the situation."

The beauty of a randomized study is that it can equalize the levels of smoking addiction, reasons for wanting to quit, and motivation to quit across groups. In addition, it equalizes other confounders, including unknown confounders which could affect the study results. There is no way for a survey study to accomplish this. Thus, to simply throw out the RCT is quite unscientific, in my opinion. It throws out one of the most valid pieces of evidence that is necessary to make an informed judgment about the effect of these products: the differences in effectiveness of the products under conditions in which confounding cannot throw off the results.

The CDC has done enough damage with its irresponsible and untruthful propaganda about electronic cigarettes. It is time that policy decisions be guided by science rather than politics. And the science is now in. It indicates that youth smoking levels are at record lows, which casts serious doubt on the hypothesis that electronic cigarettes are fueling an alarming increase in youth smoking.
