I was smoking more than 35 Years while I quit at age 45 because of Heart By pass for two years but I still continued smoking till i was introduced to E-Cigarette. I also used Chantix and I stopped for 6 months but did not work, I think E-cigarette is greatest think for smokers I even not use Organic e-juice without any Nicotine . I think other than age their should be no regulation on this device. Is much more harmless than Alcohol.
