The International Network on Health and Hepatitis in Substance Users (INHSU) is a global network dedicated to improving the health of people who use drugs, with a specific focus on hepatitis C, infectious diseases, and harms that can occur from drug use. We believe the most powerful impact is achieved when researchers, clinicians, advocates, and communities of people who use drugs come together to share knowledge, learn from each other, and put those insights into action. Our work spans three key areas; knowledge exchange, education and advocacy. Through all three, we are committed to the human rights of people who use drugs and their contribution is central to our work.
