Held once every two years in a different country around the world, the International Harm Reduction Conference has become the global focal point for knowledge-sharing, networking and promoting best practice in the field of harm reduction. The conference is attended by up to 1000 delegates from over 70 countries, including medical and policy experts, harm reduction practitioners, campaigners, and people who use drugs.

The conference will be organized this time by Harm Reduction International (HRI) and The Association des intervenants en dépendance du Québec (AIDQ), with the support of the Direction de la santé publique (DSP) of the Ministère de la Santé et des Services sociaux du Québec (Health and Social Services Ministry of Québec) and Tourisme Montréal.
