The Harm Reduction International Conference has long been a home for those dedicated to promoting health, justice and human rights-based approaches to drug use and drug policies. Harm Reduction International (HRI) has a particular interest in how harm reduction intersects with other social justice movements, and we are very excited to see this reflected in the programme as it develops. We are thrilled to announce that the upcoming Harm Reduction International Conference is a collaborative effort between HRI and our local partner, Corporación Acción Técnica Social (ATS).
