I am well into my 2nd month now and I was a 1.5-2 pack a day smoker. I started out at 24mg with 2-3 mls a day flavored and am now swinging around 12mg with the same usage. I'll hang around this watering hole 'level' of nicotine for awhile now and see how it goes. I have NOT smoked once since I started vaping. I work with horses and I can finally smell them now.
