My bro endulged his temptations and is stealing his roommates pain pills. he really wants to stop. he says he can't control himself. who can help him?

Many places: If he is in school, the school medical department can be helpful. If he has a pain pill habit already, he likely will need a detox. Talk to your family physician about ways to help him. However, nobody can ultimately help him except him. If his roommate notices the loss of his pills, your brother could get into legal trouble. Try attending alanon or families anonymous meetings
