These recordings are very sueful for someone wanting to recover or recovering from addiction. I echo Unis' suggestions, and add that there is a new one called Breaking the Habit.
It is important to have supports. A therapist, 12 step group, social and family support, are all going to be important to a person who is recovering.
Also- if it is alchohol or tranquilizers, make sure the person is medicaly supervised during detox. Withdrawing from them cam be very dangreous, so it is best done safely in a detox centre or specialized clinic. These places offer initial counseling and will also be able to refer to supports in the community.
Good luck
