Advancing psychedelic research and therapies to benefit science, healthcare, and society since 2007. OPEN Foundation is the organiser of the Interdisciplinary Conference on Psychedelic Research. Founded in 2007, the OPEN Foundation is the leading nonprofit organisation in the Netherlands and Europe dedicated to advancing the knowledge and understanding of psychedelics through research. We aim to optimise the potential of psychedelics in a therapeutic context and to help integrate psychedelics into society in a way that’s both sustainable and responsible. We fulfil our mission by bringing together and educating professionals, policymakers, and the public through conferences, trainings, membership programmes, and by facilitating and promoting rigorous, interdisciplinary research.
