Ever since we got home from college this summer my friend "k" has acted terribly different. I was holding onto bud for "m". K asks me to front him a dub cuz he has no money til the next day so he wouldnt be able to smoke later in the night when he gets home (this was at midnight after i just smoked him down on all of the monetary value to my name) . M says no to fronting the dub, so we move on. After we part ways i realize a dub is missing.. I have no other explanation for its disappearance (dont have to go into details) so i none-accusingly text k about it. He doesnt respond til the next day when he gives a contradictory story. I continue to question and he keeps making up more and more of what sounds like bullshit. Then he hints to a pre-medidated excuse to get me the $20 later. so i say to him "thats really not cool at all man", especially since i was suppose to return the bud to M already. K freaks out starts calling me all sorts of things, getting really angry like its my fault. saying our friendship is over if im gonna accuse him like that (dont really care at this point). Now k's always been a man to get his fixes whether it be alcohol, cigs or weed in the 2 years ive been really chill with him. Ive always known hes done an occassional line or 2, but it wasnt til the same night, which I hinted to my oncoming interest in cocaine, when were rapping and he says he snorts coke everyday (wasnt sure if he was serious or not) so i gotta ask gc, do i need to be worried? does this sound like typical feigning "cokehead behavior" that ive read about, or am i just being paranoid? Im really worried about this kid. Its almost like he stole the dub and he doesnt even realize why its wrong to do so. What am i supposed to do in a situation like this? Me and his little brother is all hes really got around here and i know his bro doesnt have the slightest clue to it. I dont wanna hang around this kid if hes gonna be like that but at the same time I dont wanna see one of the few people in my life that ive been able to trust the last few years ruin his life like this. so what do i do here? Appreciate anyone who can help out. thnx to sum it up: come home from college, friend hints to cocaine use, steals drugs, lies, other negative changes in behavior, how do i help him?
