Drug Consumption Rooms in Hamburg, Germany: Evaluation of the Effects on Harm Reduction and the Reduction of Public Nuisance

In order to evaluate the impact of consumption rooms (CRs) on the promotion of health among drug users and the reduction of the public nuisance of drug use, a study examining CRs in three countries was carried out in 2000. The study, supported by the European Commission, examined CRs in Rotterdam (The Netherlands), Innsbruck (Austria), and Hamburg (Germany). This paper evaluates the findings from the study of Hamburg CRs. In order to get evidence-based information on the effects of CRs, 616 drug users in the Hamburg drug scene or in the vicinity of low-threshold institutions were investigated with a standardized questionnaire. Qualitative problem-centered interviews were also carried out with staff members of the CRs, and representatives from the community, including neighborhood residents, business people, police, and politicians. Research findings show that the Hamburg CRs reached the target group of drug users who practice risky behaviors and engage in public drug use. Findings also show that the Hamburg CRs lead to positive changes in health-related behavior for drug users. In addition, the findings indicate that the Hamburg CRs played an important role in the reduction of public disturbances in the vicinity of open drug scenes.
