The seventh edition of the Interdisciplinary Conference on Psychedelic Research, ICPR 2026, will take place June 4 to 6 in Haarlem, the Netherlands. Organized by the OPEN Foundation, it is Europe’s leading scientific conference on psychedelic research, therapy, ethics, and policy.
The program brings together over 100 interdisciplinary speakers across keynotes, panel discussions, symposia, and workshops. It creates space for exchange and collaboration among researchers, clinicians, policymakers, and professionals working across the field.
Hosted at the Philharmonie in Haarlem’s historic city center, ICPR 2026 provides a focused setting to explore new scientific findings, emerging therapeutic approaches, and the ethical, societal, and policy questions shaping the future of psychedelics.
We work with partners who share a commitment to rigorous, responsible, and interdisciplinary dialogue. Their support helps make ICPR possible and strengthens collective progress in psychedelic science.
