People are individual in their response to nicotine. My dad smoked Granger, with a hiatus for King Edward cigars, for most of his adult life, but then quit cold turkey in his sixties when he went to a campus no-smoking work place. When he smoked it was from right after breakfast to bedtime, except for meals. My mom loved the drama of gesturing with cigarettes, but nicotine had no effect on her at all. I think every pack she ever owned went stale, usually more than half full. She only wanted to do her Bette Davis from time to time. My late wife was seriously hooked on nails and quit heroically on her third try from a multi-pack a day habit. I quit smoking in solidarity, just having a cigar or two away on business trips, which I told her about. My wife now was a Galoise and then Camels smoker but quit decades ago, but tolerates my pipe. I can enjoy a nic buzz when it arises, but I never pack a pipe with that objective. I had an economics professor when I was an undergrad who seemed to have two or three cigarettes going at once, with his black coffee.
