Was smoking during 46 years. Started vaping 9 months ago, and quit smoking about 6 months ago. Cheap e-cigs did not work for me. Mechanical mods with rebuildable attys do. The Allen Carr method of tobacco quitting might have worked if I was a cigarrette smoker, but I was a cigar smoker, and that’s a different thing. Today I’m vaping hi-nicotine, but not all day. Often there are several hours in between (as with the cigars). Lo-nicotine could not have done it for me, but I feel I need less nicotine now.
