I ran out of things to say, so I started reading some of the negative comments about e-cigarettes. You can screen out the cigar comments by running a search for "e-cigarettes" or "electronic cigarettes."
I've spent most of my day commenting on the negative comments. Here's one of mine:
A Ph.D should document his "facts." It never ceases to amaze me that some PhDs make statements of alleged "facts" which can be disproved with a one minute Google search.
1. "Nicotine is a very toxic substance..." And therefore, what? That can be said of many common household and garden products, all of which have appropriate warning labels and which nobody opposes for e-liquids. The highest concentration of nicotine in e-juice I've seen is 36mg/ml. I've spilled it on myself several times and it hasn't even caused a rash, much less "accidental poisoning." And it's highly soluble in water, so it's easily rinsed off. Out of all the millions of people using e-cigarettes all over the world for a number of years, there is not a single reported instance of a fatal accidental poisoning and only a minuscule number of reports involving any degree significant harm. For example, in the UK, where there are an estimated 2 million e-cigarette users, there were only two reports involving children suffering symptoms lasting more than a few hours and none with permanent ill-effects.

Phone inquiries to poison control centers are not documented cases of poisoning, although one would never know that from reading sensationalist headlines. If we were to over-regulate everything that might harm children, then adults will all be forced to live in padded cells.
2. "Nicotine is highly associated with the development of physical dependence..." Actually it isn't. Nicotine in combination with all the many other substances in combustible tobacco is associated with physical dependence. There has not been a single study done on humans showing that nicotine alone produces significant dependence.
Is Nicotine Addictive ? The animals it's been tested on don't show signs of significant physical dependence. People using nicotine gum don't develop significant physical dependence, nor do people using patches, inhalers and lozenges. I feel reasonably sure that that FDA knows these things, as it has approved these products for long term use as smoking cessation aids. The absurd analogy comparing electronic cigarettes to EDIT: the prevalent cash crop in Afghanistan casts a dark shadow over every other undocumented statement this gentlemen has made.
3. "Although e-cigarettes do not release second-hand combustion products at a level equivalent to smoked tobacco.." What was that again? E-cigarettes do not release ANY level of combustion products. And the claim that e-cigarettes "release significant amounts of nicotine in exhalations" is false. Peer reviewed studies have NOT detected significant levels of nicotine in the air from the use of e-cigarettes, even in enclosed, unventilated rooms. Here is a link to one such study:

That study concluded, "5 vapers using e-cigarettes for 5 h in a small room without renewal of indoor air do not produce
detectable levels of nicotine in the air."
