I personal think that it's bullshit, but there is a few stories of people who was smoking for 10 years and with electric cigarette stop smoked. I'm a smoker and i would like to stop that's why i need your advice.
i tried and its much better than cigarettes in every way. doesn't smell, tastes better, cheaper, won't kill you etc.
it made me quit in analog cigs in 2 weeks. just give it a shot.
