You have a good point, 3 billion dollars absolutely warrants retail outlets. It sounds like you couldn't fit enough of the variety at a gas station sized location. As far as licking the inside of my pocket, how is that more detracting than inhaling whatever chemicals are in an e-cig? I would equate that to "lick my inner pocket or take a good tongue drag across the pavement"...hmmm.
Why do you keep making this competitive?
I never said E-cigs are good for you, or that there is no harm in using them.
All I said is that they are not as bad as a real cigarette. To anybody who would be debating between using a real, vs E-cig, based on the health effects, 10 out of 10 times I would recommend the latter, because there is no question it is healthier.
But to answer your question - the difference is time scale. Putting your mouth on all that other crap will taste bad NOW, put dust and crap in your mouth that hurts you NOW, and is just gross... NOW. The adverse effects from still getting nicotine and the baked oils are much more subtle and take time to hurt you.
Not that that matters. My point was that, hell, the health effects gained by cutting out the tar and all the other stuff in the tobacco could very well be counteracted by inhaling your own pocket sweat.... eeeewww. Not to mention whatever kind of bacteria starts growing on that thing.
I'm not saying one is worse, but that you have them BOTH.
I can tell you this though - if somebody made me make the choice between a drag off a clean E-cig, or licking my pocket - I'd take that E-Cig every time.
