Prescribing drug of choice to opiate dependent drug users: A comparison of clients receiving heroin with those receiving injectable methadone at a West London drug clinic

Those choosing heroin complained that the upper dose limit was too low to maintain them adequately, and some receiving methadone complained of discomfort while injecting. Both groups were well retained in treatment. Significant reduction in drug use and crime, at 3 months, which were sustained over the 12-month follow-up period. No significant difference in treatment outcome between each group.
