I have been vaping for about 10 months now. I was a pack and a half smoker a day for about 12 years. My wife became pregnant and her doctor urged her to quit smoking immediately. She slowed then went cold turkey. I tried patches gum lozenges and cold turkey quitting bot nothing helped me to quit. I purchased a mod or a nemesis tube device and an I-go w dripper.it was the last day I smoked a cigarette. I started at 18 mg of nicotine now I’m down to 3 mg. I feel more healthy than ever and I don’t smell like an old ashtray.
