But banning e‑cigarettes will, as sure as night follows day. No one is arguing that e‑cigarettes are completely harmless; there is some evidence that the vapour created by the electric element may contain some toxins. No one is arguing that at least some people may be encouraged to switch to the “real thing” after getting addicted to e‑cigarette nicotine (although there is no evidence that people actually do this – in fact the evidence points the other way, that cigarettes lead people down the road that ends in an e-cigarette). And yes, many people who vape continue to smoke as well. Finally, we definitely do not want children buying and using electronic cigarettes, any more than we want them using real ones.
