Smoking is, for me, definitely about the habit and the ritual of doing it, rather than the nicotine. I could probably quit by going through the motions of smoking but just not lighting up, if I tried (which I haven't). I never feel "relieved" afterwards or even really have a physical urge for one... it's all mental for me.
I really should quit. Really, really.
Anyway, I've been smoking menthols since the beginning (back in the day before you could tell the difference between brands, I realized that nobody would bum cigs off me if mine were menthol, so that's what I chose). To this day, I can still walk into a party with half a pack, and walk out of the party with most of them remaining. I doubt many regular cig smokers can say the same.
To me, the difference between the two is that a menthol is a cigarette, and a non-menthol is a stick of dirty air. I'd rather not smoke than smoke non-menthol.
Honestly, I'd rather not smoke. I'm not soapboxing here... just quit while you can. The minute you stop getting a buzz when you smoke, you're officially addicted, so stop smoking while you can. Please.
