Double-blind detoxification of methadone maintenance patients

Twenty-four methadone maintenance patients were assigned to (1) decreasing dose (N = 12) or (2) continued methadone maintenance (N = 12), matching for dose, initial complaint levels, and counselor. After 14 weeks most patients in both groups had terminated from the study. Detoxifying patients usually terminated by obtaining a dose increase or dropping out; maintenance patients usually terminated for external reasons. Prior to terminating, detoxifying patients reported increased withdrawal complaints but no awareness doses had decreased. Termination was not directly related to dose level or percentage decrease. In both groups, terminators were likely to have been high in complaints during the baseline period.
