my brother's 16, he's been smoking weed for a couple of years now but has started to do it more heavily lately. he has no motivation for anything, he mostly sits around the house and makes alot of messes. he's started to lie about little things like borrowing a few dollars or where he's going and stuff like that.. i'm fed up with it. our parents are going through a divorce so i realize he is probably using weed to comfort himself but i want him to realize how much he is throwing away for a few hours of fun. do you guys have any suggestions of how to bring this up without him feeling like i'm attacking him?
