The Truth: None of the cigarette companies have claimed that electronic cigarettes are safe. Moreover, the company which Wimmer cites as evidence of his assertion is not a tobacco company at all. NEwhere is purely an electronic cigarette company. It is not owned by Big Tobacco or any other tobacco company.

You can see the quality of the scientific reasoning we are dealing with.

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.
