If this is the kind of "scientific" reasoning that is going to guide the nation's decisions on how to handle tobacco products which are killing hundreds of thousands of Americans each year, then we may actually be better off reverting back to the "wild, wild west" that Stan Glantz keeps talking about. At least in that wild west, consumers are able to make reasonable judgments about the relative safety of different products. In the FDA-regulated "east," consumers are going to be kept hidden from even the most basic truths: that electronic cigarettes do not contain tobacco and that they are much safer than the real thing.

To be valid, the study needs to examine e-cigarette smokers who have not tried these products before and are trying them for the first time in an attempt to quit smoking. Otherwise, the study cannot truly claim to draw conclusions about how helpful e-cigarettes are for smoking cessation among cancer patients.
