After Drum jumped from $4.50 to $12 a pouch, I had to invest in an electronic cigarette. Since NJoy was completely sold out, I went with http://smokingeverywhere.com/
, which from what I can tell is pretty much identical.
I've been using it for about a week now, and it has helped me cut back on cigarette smoking, although it's not quite as satisfying as a real cigarette. They did a pretty good job replicating one though. I think if I switch to the cartridges with the higher nicotine content I could probably ween myself off the cancer sticks entirely.
Aside from that, the only disappointments I've encountered are that even though they aren't cigarettes, a lot of bars still don't want you using them because they look like a cigarette and it might encourage other smokers to light up. And the cartridges are much less biodegradable than the equivalent cigarette butts.
Otherwise, I've been fully enjoying the ability to "smoke" in places where it's generally not allowed... which since there is no smell even includes bathrooms in places that don't want them used in visibility. I can now smoke inside my apartment again, and don't have to worry about ashtrays or accidental burning. Plus, since it's still unfamiliar to most people it can be a really interesting icebreaker!
