Follow-up study of subjects on methadyl acetate and methadone

Fifty of sixty original study subjects were assessed via two questionnaires and urinalysis tests between six months and one year following completion of the experimental program. Results indicate a high rate of retention in methadone/methadyl acetate treatment, and point to the need for positive social context, satisfactory interpersonal relationships, and good role functioning as concomitants to achieving drug-free status.
