Chronic heroin use during methadone treatment: A test of the efficacy of high maintenance doses

A pilot study was conducted at two maintenance programs to test the effect of increasing the methadone dose of clients who continue chronic heroin use after stabilization on methadone. Program 1 subjects (Group 1) received substantial dose increases for a 14-week period; Program 2 subjects (Group 2) received no dose modifications during the same period. Results show Group 1 reported an alleviation of physical and psychological complaints but did not decrease illicit opiate use. Group 2 maintained the low level of complaints reported at baseline and, unexpectedly, decreased opiate abuse. Because the two maintenance programs differed in clinical practices and in enforcement of rules, it was concluded that clients who continue chronic heroin use need not only long-term dosage increases, but also clear, consistently applied program policies.
