Hair analysis as a tool for monitoring and managing patients on methadone maintenance. A discussion.

Hair analysis for unprescribed drugs is not merely an effective, dignified, and time-saving alternative to urine testing. It is also more sensitive and more difficult to evade and minimises the risk of infection to clinic staff. Because of these characteristics, it can, when properly used, change the nature of the relationship between treatment personnel and patients on methadone maintenance. These changes can be beneficial and acceptable to both parties. In 263 patients, 41% of hair samples were negative for opiates, 22% had levels below 10 ng/10 mg, while in a further 7% the level was less than 20 ng/10 mg. The existing and potential advantages of this technique in managing both opiate abuse and other sorts of drug abuse are discussed.
