thats a bit tricky,i know for myself it would have to be cig.smoking but i do know others who just smoke from time to time without any cravings,kinda like myself with alcohol,use to drink 4 5 times weekly to get smashed but never no problems with abuse,just gave up entirely,now with that i would have to say the benzo non remembering time,lol, were most additive and most def.hardest to kick for ive been on some kinda of pharmaceutical a better part of 40yrs and trying to pry benzo paws off back was by far the hardest for me, I figured I'd could just replace with another drug,no way, tried to counter with oxy 80 mill/morphine etc etc to only discover no relief from the killer withdraw of the xanax nightmare,finally kicked cold turkey,thank God,anyway just thought id share. i really enjoy the Bluelight threads ,lots of incite here,thanks
