I started to stop smoking a little over a year ago. Illinois passed a smoking ban in bars and restaurants in 2008 and I went a year sitting out in the cold freezing my nuts off before finally decided that shit was stupid.
I saw a guy in a bar I frequent hitting what looked like a cigarette, but wasn't and started asking questions. Ends up it was a
nicotine vaporizer.
I've been using the vaporizer exclusively since January and I love it. Some days I can go without it, but when I'm at the bar and need a hit, it's there in my pocket and I don't have to leave the building.
The vapor is basically water, varying amounts of nicotine (I use 24mg), artificial flavors and a food additive (
Polypropylene glycol). You can get vapor in pretty much any flavor that you want. I get mine from a place in Wisconsin so I know I'm not getting Chinese cast offs.
