Problem: Xavier is a divorced 32-year-old part-time landscaper who states that his life is in a downward spiral. He has been homeless for the past 6 months and lives in his car or at friends' homes. For over one month, he had lived in a tent in the woods. After calling his parents, they had offered to pay for substance abuse treatment on the condition that they pay the treatment center directly. Xavier stated he has had issues since he was 23 when he was working two jobs trying to take care of a new wife and young son. He injured his back and was not able to go back to work due to the pain. A friend offered him Percocet for the pain so he could feel better and get back to work. He stated his pain went away and his mood and energy improved. He felt good and happy for the first time in his life.
