I hope he quits before the damage is life threatening. I am embarrassed to admit that that is what it took for me to finally quit. He has to make up his mind that he is serious about quitting and follow through with it. Nobody can force him. An easy way to find other people is through online AA and there are many, many various groups. I found intherooms dot com the most comprehensive. He doesn't have to contribute or introduce himself just register an anonymous account and attend any of the multiple meetings at every day and time.
