INHSU 2022 welcomed nearly 800 people from over 50 countries, with 2023’s conference in Geneva set to be the biggest yet. The diverse delegation and speakers include people working in the fields of infectious diseases, harm reduction, drug policy and more. Find out why people attend our conference in the videos below.



Geneva is the world hub of global health, scientific research, and innovation. Its unique ecosystem of global health organisations, not-for-profits and academic institutions makes it the ideal location to foster collaboration among diverse stakeholders, facilitating knowledge exchange and policy development, and drive change for one of the world’s most stigmatised and under-served communities.

INHSU is unique due to the cross-collaboration between different stakeholders dedicated to the health of people who use drugs. This leads to a program that facilitates balanced discussions, shared perspectives, and invaluable cross-sector learnings.


Our robust abstract review process includes world-renowned experts reviewing abstracts, with only the highest-ranking invited to present. This is continually proven by the number of studies that go on to be published in leading journals.

Over 100 sessions, including plenary sessions, workshops, posters and networking events. Topics include epidemiology and public health research, clinical research, social science and policy research, good practice models of care.


Pre-conference events include an invite-only policy day seeking to increase coverage of opioid agonist therapy globally, a community day, organised by INHSU’s Community Committee of people who use drugs, and our INHSU Prisons workshop.
