My lil bro is servely hooked on weed an bringing my family down with his problems causing life changing things for my mum depression and attempted suicide for her.... she finally plucked up the courage to leave him and move out. Except i dont think this really hit him until mum actually left. Anyways its been on the cards for a while that he has been thinking bout going to rehab..well he left today to go but i have a problem that because he asked to go and wasnt forced to go that he doesnt have to stay, im scared that when the pressure gets tought and the detoxic process starts that he will leave and go back to his old habits and desotrying his families lives again. And also another concern is that he has no goals or asperations for when and if he comes out clean. He will be going back to the house where mum left him which now is rented by his so called 'second family', whom i found out recently are actually supplying him with the drugs and make him sell them for them in order to make a profit and so they dont get caught because they have children however as he is in so much toruble with the police on bail(sentencing in mid november is possibly looking at a jail sentence which is also destroying my mum she feels this is all her fault and that she hasnt done enough to help him when she has done evrything in her power) due to getting caught high with possession and dangerous use of a fire arm that all of these things are putting him at even more risk so when he comes out being in this situation im scared and more so that its just going to be a waste of time that he will continue to sell and do drugs...what can i do? im so worried i just wish he would wake up and understand what he is doing not only to himself but to his family aswell because its affecting everyone not just him......
