Any suggestions?

A friend of mine got a hold of me last night and I asked him if he was ok?, he said not even close, I’m an alcoholic.
Now, this friend of mine is a fairly new friend, I befriended him befriended him at the end of last year. What I have come to know is he had been in rehab for drugs. And in the past has been in a car accident because of being on drugs, although he was the one who got hit by someone else. I don’t really know the whole story though. Anyways, since he has been out of rehab, he started drinking. I don’t know if he’s been treated for alcoholism too.
I suggested rehab again and he said no, drinking helps him. I said I can’t help someone who doesn’t want help. He started talking about how he wished people would just stop helping him.
I don’t know what to say and I don’t know how to help him but I’m worried about him. Does anyone have any suggestions? Know how to communicate with someone like this to get them to listen?
