Its a fantasy to believe that the e cigarettes will lead to the real thing.
Hell I grew up in a family of smokers and I was the only one who smoked consistently till several years ago and of my 4 sisters only one of them ever smoked and she was an intermittent smoker for years till she quit.
I know that. This propaganda (and that is what it is) is being pushed by the pharmaceutical industry because they are losing money from people that would otherwise be buying FAILED their prescription drugs or other nicotine replacement "therapies."
