when u smoke coke it doesnt last more than like 5 or 10 minutes, so i think its a waste

i'll do it every once in awhile...but i don't really like coke in any form or method...everyone tells me not to do it cuz i'll get addicted all my life then i finally decide to do it and it's like....man wtf is all the fuss about i'd rather have weed....now if someone wants to throw some in if i roll one up or somthin i'l do it, as like an added bonus....but i wouldn't never pay for it that's for sure
