your brother sounds a lot like me, lol. my brother sounds alot like you! but he is 21, i am 15. if i were you, i would just be real nice to him about it, maybe go pick him up, smoke with him, and explain to him your situation and what your advice is. go in his room, show him the bag, take him for A ride in the car, get blazed, go to arcade, w/e is fun, concert, i dont know. but yeah, show him bro loves him! (but will still kick his ass if hes got it coming =P)
