ABSTRACT:
Monitorable drug compositions contain known proportions by weight of a drug e.g. methadone and an isotopic analogue e.g. deuterated methadone. A urine specimen or blood specimen can be tested to reveal whether the proportion of the two constituents in the urine is the same as the proportion in the composition that was prescribed to the patient. A discrepancy will reveal that the patient has supplemented his dosage with drugs obtained from another source.
