I started a few months ago too. I actually quit smoking three years ago by dipping. My GF didn't like that I dipped and suggested I try a ecig disposable to see if I liked it. Well I did and now have found a new hobby. I love vaping and am spending a lot money on vape supplies, but I like it and its a lot healthier. My lungs have improved tremendously over the last three years, and since I have started vaping I have not seen any negative effects in that department, and I chain vape my provari all day long.
