I have been a smoker for 30 years, 1 pack a day, tried many many time to quit with the regular stuff (gum, patch, etc) and never succeeded since i use a vaping device, i have been smoke free for 6 months, and it was not very hard to quit smoking with the vapor device. (i use a regulated device with tank and dripper) i also use a mechanical device, im aware of the danger and always stay in the safe zone of the battery started at 12mg and after 1 month i’m vaping 3 mg or 0mg please dont ban the only thing that help millions of smoker to quit smoking
