Spooky sh*t

And that scared me a bit. The thing is that this Golden Virginian is NOT an unbiased scientist. And he IS on Phillip Morris' payroll in that VCU has sponsorship deals with Phillip Morris which include such contract terms as all publications being reviewed by the tobacco giant before release, and nobody being allowed to talk about Fight Club. As for the study, it was poor in my opinion (small sample of cheap generic-brand e-cigs used, no instruction to the participants on how to use them properly, etc.), and it makes no serious effort to explain why hundreds of thousands of users do get at least an apparent nicotine hit from e-cigs, and so on. And of course it has not been peer-reviewed.
Also, if the findings were correct, it would imply that smoking is not nearly as physically addictive as everyone's been saying, and the belief that one is inhaling nicotine, along with going through the motions of smoking, is enough to satisfy a smoker, which means if anything the results should prompt LESS regulation of tobacco and (especially) tobacco-free nicotine products.
Anyway, there's no doubt that nicotine exists in the e-cig vapour, at least with some models and cartridge types, other studies have already confirmed this. And the absorption of nicotine via the lungs is not exactly a novel concept. For that reason alone the study is highly suspect.
As for third-hand smoke, nitrosamines are deemed carcinogenic, but it is still all about the quantities you're exposed to. Most (all?) plants in the nightshade family contain nicotine and nitrosamines, and since apparently tobacco-specific nitrosamines can form from nicotine, then you're exposed to TSNAs when you eat a potato or a tomato. So... whatever happened to science being quantitative? It seems that all standards of science and reason go out the window as soon as tobacco comes up, not the least shining example of which is this conflation of tobacco and nicotine that is causing so much grief for e-cigs, despite their obvious potential for saving lives.
