Off topic: I don't smoke, but do generally hate smoking so much. I dislike the smell, and the affects on people around the user, like you said. I appreciate vaping. Not because of some hopeful idea that it would be safer, but cause I either can't smell it, or it smells like cotton candy. Who doesn't love the smell of cotton candy?
Also, props for quitting all the times you have. I'm probably majorly addicted to caffeine. Like smokers tell me they have one first thing in the morning, coffee is the first desire after I'm out of bed. I've already limited myself to two-ish cups/day, but I don't think that helped. Coffee also has negative effects on others...fortunately, my wife has coffee breath too :)
