I started vaping while I was smoking 3/4 to a pack a day, certainly better then my 2 pack a day habit. I then found that I just started vaping more when I purchased pvs that I liked and found flavors and brands that I liked.
When I found a flavor that I liked I would rather vape it then smoke an analog and eventually i found that I was not even finishing an analog completely because of the taste.
When I smoked the last analog in the last pack that I had, that was it, I was done with analogs!
