answer:There’s not much you really can do. People with drug and alcohol problems need to come to the realization that they have a problem for themselves and have to want to get help for themselves. It’s very, very difficult to help someone who doesn’t want to be helped or is even willing to admit that they have a problem. If you feel it won’t just make things worse, push your friend away, make him defensive, or make him resent your intrusion into his personal life, you could maybe just tell him that you are concerned about his drinking but the only one who knows whether that would be a good or bad thing is you. You may not be the first one to express concern. If your friend hears if from enough people it might get his attention eventually.
