International Harm Reduction Unit (IHRU)

As harm reduction theory and practice becomes increasingly well established as an effective approach towards reducing the negative consequences of drug use, there is a growing demand for rigorous and comprehensive intellectual and educational support for service providers and policy-makers.  Within this context, the GDPO’s International Harm Reduction Unit (IHRU) offers consultancy, professional training and research services to a wide variety of public and private sector clients.  Drawing on an extensive network of practitioners and researchers, the Unit’s core team is supplemented according to the requirements of individual projects and consultancies.
