A method of monitoring compliance of a patient that has been placed on a methadone maintenance program by determining plasma methadone concentration from urine methadone concentration. An unadulterated urine sample is obtained from the patient. The urine methadone concentration, pH, and specific gravity are measured. The plasma methadone concentration is calculated as a function of urine methadone concentration, specific gravity, and pH. The calculated plasma methadone concentration is compared with an expected value for the maintenance program prescribed.
