I used to smoke constantly and now I vape constantly. A co-worker turned me on to Vermont Vaper; another coworker saw me and got a kit for his mother (saving lives one at a time...)
I had to quit smoking because of emphysema and I gained 30 pounds. In the month or so since I've been vaping, I've lost 15 of it back (
so far). (Prior results don't guarantee future outcomes.)
