Global scientific platform for addiction medicine

The International Society of Addiction Medicine (ISAM) is the leading international professional association for physicians and professionals involved in the prevention, diagnosis, and treatment of addiction. The annual ISAM congress is the central international platform for knowledge exchange, research presentations, and professional development in the field of addiction medicine. The Netherlands has a long tradition in addiction research: several Dutch institutes are affiliated with universities and treatment centers, and in 2012, the Royal Dutch Medical Association (KNMG) recognized addiction medicine as an official profile with a two-year, full-time program.

The overarching conference theme is “Improving Addiction Treatment Outcomes: Tackling Old and New Challenges.” The program consists of keynote lectures, symposia, oral presentations, workshops, and poster presentations on 25 topics, including recovery management and relapse prevention, rehabilitation, behavioral addiction, trauma and addiction, harm reduction, women and addiction, treatment of opioid, stimulant, and alcohol use disorders, new psychoactive substances, comorbidity (psychiatric and somatic), ethics, epidemiology, stigma reduction, and innovations in prevention, diagnostics, and therapy. The Global Addiction Therapeutics Innovation Day (GATID) 2026 will take place on Wednesday, September 30th, for which separate registration is required.
