Hi everyone not sure what to do - i was putting laundry away in my son's room and i found a couple of empty cigarette packs on the floor i opened them to make sure they were empty-should not have done that-i found these little packets which were empty it had some white powder in them already gone i also found a very tiny tiny plastic bag looked like it may have contained some type of pill-is the white power cocaine or heroin-how would i know if was using this stuff-i would think he was snorting this-his regular drug using friends have left town-he is now hanging around with another bunch of them-one who was just arrested for possessing pot and lsd and cocaine-i asked him about it and he denied using anything but pot-i did mention to husband what i found and he said we cannot make him admit anything when he gets in trouble again he is out of our house-i was really upset when i found out about pot i am not sure how i will handle harder stuff-the husband has a business trip this week and i am going with him-i was looking forward to going with him but now this find has put a damper on the trip-what signs do i look for that he is using more than pot?????
