I'm a non-smoker, but enjoy the effects of nicotine, and also find its effects on concentration etc useful when working. I've tried wearing patches during coding binges to (non-scientific) success.

The only real concern I'd have about vaping is forming an oral habit / gesture habit. What's your experience with this?

Also, what's a good spot to dive into the community, especially to find quality products? I'm in France - huge consumers of e-cigs, but there are plenty of cheap ones - I'd like to avoid using 'dangerous' flavours - an would probably prefer to mix the juice myself.

Thanks !
