I smoked regular cigarettes off and on for over 30 yrs, I tried the patches twice in that time frame, but was never able to completely stay off cigarettes. I heard about vaping from a co worker in February 2013, tried it and have not had a cigarette since. I have gradually lowered the level of Nicotine from 1.8% down to 0.3% . I currently use an open system, Nautilus Aspire with an eleaf Istick battery system, or a VAMO brand MOD I feel better, breathe better, (and smell better) my Doctor says that my lung function has improved dramatically since I started vaping. My wife (who has never smoked) says that it has changed her life too, since I don’t have to run outside for a smoke, and that I am much more relaxed and even tempered since I started vaping.
