I’ve been a heavy smoker for more than 40 years – ++20 cigarettes a day. I tried my first e-cigarette for more than 2,5 years ago – quit smoking the very same day. Never missed smoking at all. Never tried anyother products to quit, since I know it wouldn’t works for me. The only reason I tried the e-cig was so I wouldn’t have to go outside in -15 in a snow storm to be able to smoke. But it turned out that I quit smoking all together. I started with 18mg and am now down to 6mg. I use the EVOD 2. My breathing is much better -finally able to breath through my nose again, and now I can smell how awefull smokers smell. No negative effects from vaping. My doctor changed my status in my med. journal to Non smoker 2,5 years since I had my last cigarett – never ever thought I’d be able to give up smoking, but it was soooo easy thanks to vaping!
