My 21 year old brother has had a substance abuse problem since he was 15. He's smoked weed, done cocaine, meth a few times, acid, and those are the ones I actually know about. Over the past year or so, I've heard he's been doing roxies occassionally. Last night his exgirlfriend called my parents and said she was getting text from mutual friends saying they were worried about my brother because he was depressed and taking 4 or 5 roxies a day and drinking on top of that. He's lost a lot of weight and looks like death. I confronted him about the roxies tonight and he admitted to taking 1 or 2 a few times a week but that was all he said. I suggested maybe he could see a professional about getting help and he said (of coarse) he doesn't need help. What am I supposed to do? Does he need to be in rehab? I don't think he could do outpatient therapy. He's tried that before for other things and he's never stuck with it. Please help me if you have any information. He's my bestfriend and I won't forgive myself if anything happens to him.
