I’ve heard from many long time users that those cravings never really go away. But I wouldn’t describe it as “cravings.” I would describe it as rose colored glasses. You’re reminded of the sensation/taste/whatever when you see someone else smoke or you smell cigarettes (cigarettes still smell good to me, years after I’ve quit. But they always smelled good to me, even when I was a kid. Burning cigarettes, not ashtray. That shits gross.), so you only remember he good parts of smoking. When you go back, you kinda have to push through a period of not even enjoying it. At least I did most recently. But the most recent time I quit, I quit at like 27 and started again at like 34. I smoked 1-2/day for a while, but it always just made me feel like shit. If I started smoking constantly again, that feeling would’ve gone away. But I never pushed past it.
