idk what to do anymore. My little brother is abusing drugs (he's underage) and I've noticed a huge decline in him. He is always angry and aggressive, has stopped talking to us but is really nasty when he occasionally does. He's barely ever home and he looks terrible (in a health sense). He gets his pay-check and then the next day or two claims he has no money left but he doesn't bring anything home that he might've purchased. I have no doubt he is using heavy shit and has or is becoming addicted. I'm so worried for him and honestly don't know what to do. The family has tried talking to him and offering help and he just gets aggressive and storms out. It's hurting my mom so bad and is starting to have an impact on the entire family. I don't have many options that can help him because discipline and/or caring or treatment approaches don't work. Mom offered to help him the other day and he punched a hole through the door and left the house for two days. It's at the point I feel like I need to call the cops on him but I think that would make him worse. I'm so lost and terrified that I'm going to lose my little brother.
P.S. all his friends that I know of are all doing it as well. I didn't mind when he was only doing w**d but now he is doing heavier shit and his friends are dealing it as well. I wish I had a way for him to leave his friends and find new people that could inspire him to quit and stop losing himself.
