Random urine analyses from drug addicts in a methadone treatment programme

Random testing of urine from opiate addicts in the methadone treatment programme at the Drug Dependency Service, Brisbane Street, Sydney, was carried out for 18 months. Six samples from each of approximately 100 clients (that is, 580 specimens) have been analysed. It was found that clients receiving high methadone dosages (80 mg and over) used illegal opiates significantly less frequently than those on lower dosages. Furthermore, a decline in the use of illegal opiates and an increase in the proportion of "clear" urine specimens (that is, clear of all drugs except methadone) were indicators of the effectiveness of the methadone programme. It was concluded that urine testing was a useful and objective means of evaluating methadone or any other drug addiction treatment programme, and of monitoring what other drugs were being taken, both consciously or inadvertently in combinations. The results of urine testing can also be of value to counsellors in the therapeutic situation.
