First, as a recovering person I try to hang out with healthy individuals. I have a friend with untreated alcoholism that I check on but I don't try to change her or spend any time with her. You can do service work anonymously at shelters. It suits me at this stage of recovery.
I would suggest not being the one to try and help your friend. From your post, it sounds like you have a lot of judgement towards him and you don't have faith that he can succeed. it sounds like if he doesn't agree with your suggestions you think he will fail.
When someone is ill I offer them a bed and food, a ride to the salvation army or the ER. When they are ready, they will choose their path.
PS This is not the start of an AA/nonAA discussion. It's too bad that seems to happen.
