This randomized clinical trial will evaluate two induction strategies for helping out-of-treatment opioid abusers transition to methadone maintenance treatment. All study participants (n = 120) will be new admissions to the Addiction Treatment Services at Hopkins Bayview (ATS), stabilized on 80 mg of methadone, and randomly assigned to one of two study conditions. The experimental induction condition will receive low threshold stepped care (LTSC) for the first 3-month of treatment that reduces the counseling demands of maintenance treatment (i.e., one counseling session / month). This condition will be compared to routine stepped care (RSC) for the first 3-months, which provides escalating intensity of counseling schedules contingent on drug use or poor adherence. RSC is routine treatment at ATS. All participants will receive routine stepped care following the 3-month induction phase, and will have the opportunity to remain in treatment at ATS following study participation. Participation is for 4-months. Retention is the primary outcome. Participants will also submit urine samples weekly on a random schedule each month. We hypothesize that LTSC participants will exhibit better retention than RSC participants, and that both conditions will exhibit reductions in drug use compared to baseline.
