<human>: So here's the story. When my brother started high school, he started on the fast track to failure. He's knee deep in god knows what drugs as we speak and his room is littered with cold shots. He skips classes everyday, didn't finish all his credits for grade 9, let alone the ones he needs for the grade he's SUPPOSED to be in now. And my mom doesn't know what to do. 

She has 4 kids- me (19), my deadbeat brother (16), my other brother (almost 15), and my youngest brother (also, almost 15) who's blind and mildly autistic. She's also a single parent (my dad's basically out of the picture). All she wants is to be able to leave and go to camp with her long-term boyfriend for a couple days now and then without having to worry about deadbeat brother doing something stupid. He wasn't supposed to have friends over this weekend (because they'll sit in his room and smoke pot and drink, and why should I have to be responsible for that?) but he hasn't listened to that rule once (they've been flushed out 3 times). 

My family even had a little intervention thing not that long ago, which seems to have had no effect. Even my dad came into town and helped. No improvement whatsoever.

What do, Reddit? How do we make him see how shitty he's making everyone else's lives around him? How do we make him see he's ruining his own future too? How can I get my mom a break? 

...

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: my brother is a deadbeat (skips classes, does drugs, drinks heavily, doesn't listen) and my mom is going to lose it pretty soon. All she wants is a weekend off. How do we fix?
