I'm two years and 3 months out from my last cigarette. I smoked 6 a day (from a lifetime habit of 2PAD) for a couple of years before that (thanks to vaping). If I had known how easy it was to vape and quit after vaping for a couple of months, I would be over 4 years out from tobacco.
If you haven't completely quit, dump the smokes and vape your head off! It works.
