Not that I disagree with your broader point at all -- and I say this as a former cigarette smoker, former e-cig vaper, present-day nicotine gum chewer, etc. (who is incredibly grateful for the existence of the latter two creations, or would have never quit smoking): To be fair, though, e-cigs haven't been around nearly long enough to do any sort of longitudinal study on toxicity. We really have no idea what smoking one for twenty years will do, what kind of cancers it can give one, etc. And to be absolutely fair to your point, that's also true of lots of other chemical novelties and gewgaws.
