What I find interesting though, is that while the spray does indeed get rid of the cravings, it (and the e-cigs I've used) is not the same "feeling" as smoking. This is possibly because of the lack of any MAOIs in the liquid itself.
How many of those using e-cigs here are ex-smokers? How many picked it up because it's a socially "acceptable" drug that you can now take without killing yourself slowly? I find it such a fascinating topic!
