The Interdisciplinary Conference on Psychedelic Research (ICPR) is Europe’s leading academic conference dedicated to advancing psychedelic research and therapies organised by the OPEN Foundation since 2010. ICPR is a biennial conference focused on high-quality scientific and scholarly research into psychedelics. ICPR 2024 is our 6th event. After our hugely successful conference in 2022, we are returning to the prestigious Philharmonie Theatre! ICPR will take place in Haarlem (next to Amsterdam) from June 6th to June 8th, 2024.
