Vaping helped me get off cigarettes, and now that I'm down to 0mg, I'll probably get off the vape soon too. Honestly, I will take whatever minor health issues might come from vaping over the absolute health concerns (ie. cancer) that has already taken multiple family members. Whatever else happens, I know that I wouldn't have quit without something that gave me the hand to mouth movement, the chemical addition was nothing next to that.
For the majority of people, that's exactly why they got into vaping, to quit smoking cigarettes. I'm glad that vaping has had such a positive impact in your life. I too enjoy smoking the 0mg nicotine e-juice when I'm just craving something to satisfy an oral-fixation and not necessarily just nicotine.
