MRF,
Welcome to SR, i hope things are hoing well with his detox. Remeber that as much as he is going through he needs to be able to stand on his own two feet, (i.e. learn to speak and or write in English) you will not always be around him 24 hours a day! I hope you can find AA for Russians!
Perhaps he could begin some English as a Foreign Language courses? Here in Britian they are called ESL courses.
