My little brother's just turned 14 yesterday and has revealed that hes been going out drinking and smoking weed and fighting for the past year. Im really dissapointed with him. He's far too young and he and my mum are almost being kicked out of their flat because of his behaviour, which I now realise was fuelled by buckfast.
He just came in a "tanned a bottle of bucky". What a cunt.

What should I do?
