Dependent opioid users assessed for methadone treatment in Otago: patterns of drug use.

AIMS: To provide detailed information about the types of drugs used and the patterns of drug use for injecting drug users presenting for methadone treatment.

METHODS

A retrospective case note review was carried out for 126 consecutive clients who were assessed for methadone treatment in the Otago province over a 2 year period. Patterns of drug use in the three months prior to presentation were recorded.

RESULTS

Over 60% of those presenting were using three or more opioid drugs, with the most common being homebake (63%), sustained release morphine sulphate tablets (62%), buprenorphine (52%), opium poppies (50%) and methadone (41%). Use of diacetylmorphine (heroin) was reported primarily by those returning from recent overseas travel. Most clients reported the regular use of multiple other of clients using benzodiazepines daily. Almost 80% of the group were regular tobacco smokers and 11% showed evidence of alcohol disorders (abuse or dependence). Low levels of use were reported for cocaine, amphetamines, and hallucinogens.

CONCLUSION

These patterns of drug use have important implications for the planning of methadone treatment programmes.
