I think that my oldest nephew is doing drugs. No....I know my nephew is doing drugs, but I am not sure which ones are his drug or drugs of choice. I'm 23 and he is 19 there is a 4 year age difference. We grew up together, and he feels more like my brother than just my nephew. In the past few years we haven't been as close as we used to, we were best buds growing up, we played together, rode bikes, built tree houses, everything siblings would do. Things have changed with him, the people he hangs with his attitude, literally everything. At first I thought that he may be smoking marijuana, because he reeks of smoke that didn't smell like cigarette smoke, so I assumed it was marijunana, but now I am thinking that he may be smoking crack as well as snorting cocaine. I don't know for sure. He hangs out with people that I wouldn't let my dog around much less anyone else. Who he hangs out with changes frequently, and he knows more people than there are listed in the phone book. The other day he brought one of his new "buds" around and they went into his room and shut the door and I could hear them in there making snorting noises. I went in there after they left to see if I could find any evidence like a powdery substance, but the only thing I found was some green specs that could be left over from some weed he previously had. If I try to ask him about it, he denies it and gets mad and starts yelling that no one trusts him, that he doesn't do that stuff, he gets loud and defensive and just plain mad. He is moody, he is easily angered and he is just loud in general. I don't know what to do. There is no point in trying to talk to him because he gets mad and denies it. I honestly don't know what to do. I do know one thing is certain, if he keeps going on the way he is, he will either end up dead somewhere or facing 25 to life behind bars. Does anyone know what more I can do to get him some help? He drives after he does the drugs, and I'm afraid that he will not only kill himself in an accident but other innocent people as well. It kills me inside to know that he does this and I don't know how to help him. I have thought about just not worrying about him anymore, but I could never live with myself if because of his stupidity and carelessness he killed someone else.
