meh, i belive it can vary from person to person how addictive it is.
i was a textbook addict in that i used everyday (multiple times a day) but when i finally made a full bore attempt to quit it was relatively easy...first few days mildly annoyed and diet was off (nut hungry)...but overall not difficult.
snuff tobacco is 100 times more difficult i've made multiple attempts at quitting and never have been successful.
first real attempt at perma quitting weeds, almost 7 months so far and no inkling to breakdown and i'm surrounded by the shit in cheap abundance.
some other boards based about quitting tweeds i've visited, it appears that others struggle a lot more than i did. largely a mental toughness thing i suppose
