Well, as a smoker who'd like to quit, I don't care for their taste or the sensation. From a public health perspective, as they carry many of the same risks (and potentially others) as traditional cigarettes, it's probably not a viable alternative and should be scrutinised to the same regulatory extent that tobacco is. Not to say that I'd discourage anyone from using it; my brother used one to avoid cigarettes and it seemed to work for him. But I don't see any indication that it is some sort of cure for rampant nicotine addiction. Secondhand smoke is just one problem, and admittedly a major one, presented by smoking. The costs associated with ailments that smokers experience still ultimately affect all of us.
How so? There is no tobacco in them. Nicotine in and of itself is not what kills the smoker. I know these are very obvious to you but how can inhaling tobacco smoke and flavored water vapor carry the same risks? None of this has been proven, and most anti-eCig propaganda is funded by
1. Pharmaceutical and insurance industry, who want you to chill out with
their poison.
2. Tobacco companies, obviously.
The enemy of thy enemy is thy friend, yes? This is why the common man should be so fed up with the system in which we live. You MAY NOT have your cake and eat it, too, unless someone more powerful than you is profiting. And the eCig manufacturers are pipsqueaks compared to Pharm Inc. and their collection of monsters.
