I still smoke, but pretty lightly, 3-5 a day at most, compared to what I used to go through, a pack of cigars and 25g of rolling baccy in 2 days or so.
Got one of those E-fags (no I don't mean alex plank:P) and like it so far. Although they seem fairly dangerous, based on design, the nicotine reservoir part detaches way too easily, and indeed, I've heard of more than one case of accidental poisoning via the transdermal route, when someone had one break open in their pocket, spilling liquid everywhere. Nicotine passes through the skin very well, so well, in fact, that I sometimes, wanting a slightly more prolonged release nicotine dose, just squeeze a couple of small drops from the bottle onto the inside of my wrist where the skin is thin, works just fine.
Another potential issue, is that they are far from standardized, and in a study of 6-7 brands, not ONE of them, contained the advertized concentration of nicotine. Some contained a third of it, some contained twice as much or more.
And considering the strong variety of liquid made for my kind of E-cig, is meant contain 24mg/ml, and the reservoir of the E-cig contains a little short of 3ml...that is much more than a potential lethal dose, were it all to escape and contact the skin unnoticed. (some 30-50mg or so is an average human lethal dose). I never, ever fill mine as much as it will hold, for that reason, to limit the potential for harm, should it pop open. It has done, at least three times, while trying to unscrew the battery to charge it via my USB port. Twice its spilled all over me, luckily I was within reach of something to clean it off, and quickly, each time.
