PROCEDURE: Participants in Natural Recovery received a one-hour small group therapy session during the week using modules with a staff facilitator while DAP-CP participants attended a large psychoeducational group at that time. Participants in Natural Recovery were given a choice of tracks, either Horticulture or Art/Music based on personal preference. The modules employ analogies between the recovery process and their chosen hobby. Although hobbies were different between the two tracks of Natural Recovery, the fourteen modules covered the same concepts; only the analogy portion of each handout differed.
