The Interdisciplinary Conference on Psychedelic Research

Posted by:

ICPR gathers world-leading experts across multiple academic disciplines, including psychiatry, psychology, neuroscience, anthropology, ethnobotany, and philosophy, for a multidisciplinary scientific conference encompassing academia, therapy, research, clinical practice, policymaking, and public engagement. With experts from psychiatry, neuroscience, psychology, anthropology. Organised by the OPEN Foundation since 2010, this remarkable event is now gearing up for its sixth edition following the success of ICPR 2022. We are delighted to announce its return in 2024.

Psychedelic research does not take place in a vacuum. ICPR explicitly addresses biases and blind spots, encouraging reflective and critical engagement. We stimulate deep discussions and critical thinking related to real-world issues, such as ethics, policy and regulation, the psychedelic industry, and broader questions around inclusivity, accessibility, and sustainability.
