...but I wouldn't bring up to him what he is doing wrong more than showing him the light. It may make him back away from getting the help he really needs. I don't know what state you all live in, but many do have some ways of getting some help, or a church might help. Just be careful...you shouldn't do it on your own. Maybe get others involved in helping him with you. See if he will let you talk to his family or find out who they are as well.
