Tobacco is ridiculously hard to quit. I quit cigarettes on Jan 1, 1978, but smoked a pipe and occasional cigar until October 1989. From then until 2002 or 03, I would get occasional feelings of how a cigarette would taste good after a meal, or some other situation. Fortunately those feelings are finally gone. But, I am convinced that it would only take a few cigarettes to be back to a pack a day.
Never had that from marijuana
