Residential therapeutic communities (TCs) have demonstrated effectiveness, yet for the most part they adhere to a drug-free ideology that is incompatible with methadone maintenance (MM). This study compared MM to non-MM clients enrolled in a TC, testing the statistical hypothesis that the two groups were equivalent. The sample consisted of 125 MM and 106 non-MM clients. Assessments were conducted at 6, 12, 18, and 24 months. Clients in both groups were opiate-dependent and matched on psychiatric history, criminal justice pressure, and expected length of stay in the TC. Primary hypotheses were that retention in the TC and illicit opiate use would be equivalent between MM and non-MM groups. Secondary hypotheses were that stimulant, benzodiazepine, and alcohol use, as well as HIV risk behaviors and criminal behaviors, would be equivalent between groups. As expected, MM and non-MM groups were statistically equivalent on retention in the TC (166.5 days for the MM group versus 180.2 days for the non-MM group) and illicit opiate use. MM and non-MM groups were also equivalent on stimulant and alcohol use. The groups were statistically equivalent for benzodiazepine use at all assessments except at 24 months where 7% of the MM group and none of the non-MM group tested positive. Regarding HIV risk behaviors, the groups were equivalent at all observation points. These findings suggest that methadone patients fared as well as other opiate users in TC treatment, and provide additional evidence that TCs can be successfully modified to accommodate methadone maintained patients.
