A preliminary survey of Italian intravenous heroin users in London.

The present study analyses the phenomenon of the migration to London of Italian intravenous drug users. Using structured questionnaires and prevalence data it was estimated that a significant number of Italian intravenous drug users (at least 1000) were living in London at the time of the study (1990), of whom 30% were HIV positive. Risk-taking behaviour was disturbingly high. The reasons for migrating were identified, and the implications of recent Italian legislation are briefly discussed. The data indicated that the living conditions of these immigrants in London were precarious and that these vulnerable individuals had little access to services. As the barriers to travel within the European Community disappear, the public health problems represented by the migration of problem-drug users are likely to become more acute.
