Weekly preannounced and unannounced urine testing was compared in a counterbalanced design with two random samples of clients (n = 74) from a methadone maintenance program. Results indicated no significant differences in the detected rate of positive specimens for the two types of testing. Clients reported preference for the preannounced testing and indicated that testing was not very helpful in avoiding the use of illicit drugs. The merits of psychosocial procedures in response to the outcome of monitoring are discussed.
