A city looks at its problem of drug abuse by injection.

A retrospective, multi-source screening study has detected 148 users (110 males, 38 females) of intravenous drugs who presented to all relevant agencies between 1971 and 1973 in Bristol, a city where maintenance therapy is a very infrequent practice. The peak prevalence was found in the age group 20-24 years, and it appeared that the chief sources of drugs were burglaries of chemists' shops and general practitioner prescriptions. Sixty-four per cent of our users had not been notified to the Home Office. Suggestions are made for the future monitoring and development of services. [ABSTRACT FROM AUTHOR]
