12 had " other complications." Sixty-seven managed to take drugs illicitly while in hospital. One year later 13 had died, 4 were taking heroin, and 9 another opiate, 19 were in prison in hospital or out of the U.K., and only 15 were otherwise off drugs. We are grateful to the Dangerous Drugs branch of the Home Office, and particularly Mr. H. B. Smear, for help in following up these patients. REPERENCRS Bejerot, L. N. (1966).
