I have smoked for more than 20 years, and have started using e-cigarettes (personal vaporizers) for about 2 weeks now. I don’t smoke a real tobacco cigarette at all now. I did 1 a day for the first week, but now, I don’t even touch any anymore. I don’t feel the need to because it’s working great for my need. I’m on 12mg e-liquid and I have been a Marlboro Lights smoker for the past 20 years or so. My habit was about 2/3 to 1 full pack a day depending. I have tried to quit many times in the past (by free-will), but never lasted more than a week. My quality of life has never been better! My wife does not nag at me anymore, I smell great! I can breathe better (especially in the morning) and I can honestly say that my awareness has been quite up to par when I was getting the nicotine from those Marlboro Lights. If I had been introduced to vaping much sooner, my life would have been much better earlier couple of years ago!! Sincerely, Jason Liu California Ex-smoker, Now Vaper.
