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.

The Harm Reduction International Conference is convened by Harm Reduction International in a different city every two years. Over four days of presentations, workshops, films, networking events and more, the conference provides a dynamic forum to share the latest research and discussions on best practice in drug use, harm reduction and human rights and attracts a diverse group of over 1,000 delegates and speakers including front-line health workers, academics, researchers, policy makers, politicians, UN representatives, people who use drugs, sex workers and people working in the criminal legal system.  

Our theme 'Sowing Change to Harvest Justice' considers the challenges Colombia has faced as a country producing drugs and the impact of drug policies on the climate. We come together at the conference to create pathways to peace and justice in the future.

The Harm Reduction International Conference 2025 (HR25) will be held in Bogotá, Colombia on 27-30 April 2025.

Colombia's strong civil society has a long history of providing exemplary harm reduction services. Additionally, in October 2023, Colombia’s new government announced a bold new drug policy that broke away from the war on drugs. It focused on opportunity and justice.

The Harm Reduction International Conference is going to Colombia to support a country that is taking the leap towards a new paradigm and to learn from the country and region.
