That was a great video! Glad to see some objective reporting on this issue. I'm concerned that nicotine vaporizers could suffer the fate of the alcohol vaporizor (google awolmachine), which never got off the ground. Several states banned it as soon as they heard about it... no testing, NOTHING! (although I definitely see it as more dangerous from the outset, I don't think any product deserves immediate, unqualified criminalization).
Supposedly rational people in the public health arena have become too evangelical in their war against tobacco. That, combined with the conniving pharmaceutical and big tobacco industries, could lead to our hobby never getting a chance.
Though it's a "pipe" dream, I'd like to see the electronic nicotine inhaler become the focus of a partnership between big tobacco, pharma, and public health. If they combined their efforts, did studies, pushed the product (over cigarettes, patches, gum, etc.), even allowed advertising, cigarette sales would go to nothing in no time. I believe that, if they knew about and tried it, most smokers who live in places where there are smoking bans would voluntarily quit within about 2 years.
