For non-smokers, less is more... nicotine is a pretty powerful stimulant, you don't necessarily want strong hits. My 2¢.

(I am a non-smoker; have tried 2mg and 4mg gum, and find 4mg similar in some ways to having a 'bad trip'. (Light-headedness, freaking out, nausea, time-dilation.))

true, as a smoker trying to ween myself to something a bit safer that lack of hit is what annoyed me with other e-cig solutions I tried. The nova tank though is a very tolerable substitute to actual smoking.

If I was a non-smoker though I would not start a nicotine habit at all. I wish I had never started smoking, it's a very difficult habit to reverse.

Anecdotal, but as a non-smoker, I don't find any withdrawal or cravings symptoms at all when I stop consuming nicotine. It's milder than stopping caffeine.

I also gave lozenges a try after reading an article here, and found 2mg to be too much, at first. You get used to it, though.
