I converted after months of occasionally seeing a friend of mine doing it. I was able to convert a coworker easily... It just doesn't seem to 'sink in' to most smokers immediately that there are no *real* drawbacks to vaping vs smoking.... Seems like they all come around after a while, Just gotta keep going out on 'smoke' breaks and let the smokers ask "So you don't want a real cig?" (over and over again) ... lol no. What gets me is the people that just don't want to quit smoking. Really? so much money, so many negatives... and they're just happy with it. lol.
