The Harm Reduction International Conference has helped to put harm reduction on the map for over thirty years. We platform thought leaders, amplify advocacy for change, and shine a light on local innovations in harm reduction.
In April 2025, over 1,000 participants from 60+ countries came together for the Harm Reduction International Conference 2025, our most ambitious edition yet. Across four packed days of discussion, collaboration, and critical reflection, we explored the theme Sowing Change to Harvest Justice – sparking new ideas, shared challenges, and a renewed sense of solidarity.
We’d like to thank everyone who made HR25 such a powerful experience: delegates, speakers, volunteers, sponsors, exhibitors, and all those who contributed behind the scenes.
1,000+ attendees from over 60 countries

Harm Reduction International has been convening the Harm Reduction International Conference since 1990. From its roots in Liverpool, the conference has grown to become the leading international forum on harm reduction and drug use.
Harm Reduction International (HRI) envisions a world in which drug policies uphold dignity, health and rights. We use data and advocacy to promote harm reduction and drug policy reform. We show how rights-based, evidence-informed responses to drugs contribute to healthier, safer societies, and why investing in harm reduction makes sense.
Hosting the Harm Reduction International Conference is a collaborative effort between HRI and our partner in the host country. We rely on our local partner for essential local knowledge, connections and experience. Our partner for HR25 was Corporación Acción Técnica Social.
The Corporación Acción Técnica Social (ATS) is a civil society organisation that works on drug policy reform, harm reduction, drug market regulation, human rights and consumer participation.
The Local Support Committee is a gathering of different civil society organizations and some institutional actors with the aim of promoting the conference in Colombia and Latin America, motivating the inclusion of topics of interest to the region, contributing to logistical aspects, relationships with media, and the team of volunteers, among other matters. This Committee began with some of the organisations that accompanied Corporación ATS in its application for Bogotá to host the conference, among them: Elementa, Dejusticia, Temblores, Corporación Viviendo, Fundación Ideas Paz, Procrear, Fescol, Viso Mutop, Instituto RIA, Teméride and public institutions of national order such as the Ministry of Health, the Ministry of Justice, Ministry of Foreign Affairs and of local order such as the Council for International Relations and the Secretary of Health of Bogotá, among others, joined further into the process.
