The Beginning…

Founded in 2007, the OPEN Foundation had a unique goal: to advance psychedelic research. OPEN's psychedelic conferences, later named ICPR, quickly gained international recognition. In 2022, OPEN's conference celebrates its 5th edition. Looking ahead, the momentum continues to build as we eagerly anticipate the 6th edition of ICPR in 2024.

From 2007 to 2010

A resurgence of interest in psychedelics emerged in the mid-2000s. Key foundational events, such as Gaia Media's 2006 LSD Symposium, held in honor of Albert Hofmann's 100th birthday, and the 2008 World Psychedelic Forum, solidified and fueled this renewed enthusiasm.

In 2007, the OPEN Foundation ('Stichting OPEN' in Dutch) was established. Following several years of organizing individual university lectures, we hosted our inaugural two-day conference in 2010 at the University of Amsterdam, titled 'Mind Altering Science.' This same year, MAPS organized its first Psychedelic Science conference, and our British counterparts launched Breaking Convention in Kent the following year.

Mind Altering Science 2010

Hosting a weekend-long conference at the University of Amsterdam was a new experience for all of us, but it turned out to be a tremendous success! With over 450 participants at our inaugural event, 'Mind Altering Science,' we highlighted, among other significant findings, the outcomes of two Swiss randomised controlled trials: one on MDMA-assisted psychotherapy for PTSD and another on LSD-assisted therapy for anxiety in terminally ill patients. The event also featured Torsten Passie, a valued and long-standing collaborator of OPEN, who embodies the spirit of Encyclopedia Psychedelia. Notably, he is the only speaker to have graced the stage at all of our conferences.
Two other names that stood out at Mind Altering Science – and who have sadly passed away since then – were renowned ayahuasca psychopharmacologist Jordi Riba and Andrew Sewell, who is a neurologist and cluster headache research pioneer at Yale University. 

EARS 2011

In 2011, OPEN collaborated with Dr. Bia Labate (of Chacruna fame) and Dr. Brian Anderson (currently at UCSF) to organize a modest symposium. This event brought together researchers from across Europe who had been studying ayahuasca and DMT within diverse fields such as anthropology, neuroscience, psychology, and religious studies. With over 300 attendees at the University of Amsterdam, it was a resounding success.

The following morning, the symposium presenters joined other European ayahuasca scholars for a closed-door research workgroup. This gathering aimed to stimulate future ayahuasca research and potential collaborations in Europe. The workgroup achieved several milestones, including the creation of a shared knowledge repository for ongoing and planned ayahuasca research, fostering discussions on research methodologies and securing institutional approvals. Additionally, it played a crucial role in cultivating personal and professional connections among the relatively small community of ayahuasca researchers based in Europe.

ICPR 2012

ICPR's second edition, its inaugural event under its current name, was launched on October 6 and 7, 2012, at Waterlooplein in Amsterdam. Professor Wouter Hanegraaf inaugurated the event with an enlightening lecture on entheogenic religions. The stained glass elements of the Aaron & Moses Church provided an ideal backdrop for his thought-provoking discourse. The event saw a full house with approximately 400 enthusiastic attendees, who were captivated by lectures from notable speakers such as Ben Sessa, Robin Carhart-Harris, and Matt Johnson, all of whom were featured in a Dutch documentary on psychedelic treatments. Other esteemed speakers included Ilsa Jerome, Mitzi Waltz, Jordi Riba, and Torsten Passie.

ICPR 2016

After a four-year hiatus, ICPR made a triumphant return to Amsterdam in 2016. This time, the charming canalside Amsterdam-school building ‘The Jewel’ served as the picturesque venue during some of the most delightful summer days the Netherlands had to offer. The atrium's glass roof beautifully illuminated ICPR's 550 attendees.


This marked the first occasion where ICPR extended to three days and featured two concurrent tracks. ICPR 2016 boasted an impressive lineup of over 60 speakers, including notable figures like Alicia Danforth, Roland Griffiths, Marcela Ot’alora, Bill Richards, and, of course, Torsten Passie.

A substantial portion of ICPR 2016 was meticulously documented and resides

ICPR 2020 Online

Organizing ICPR 2020 was a monumental effort that spanned over one and a half years, involving nearly two entirely new teams and numerous digital meetings. The journey was almost derailed entirely due to unforeseen challenges. Initially set for April 2020 at the Philharmonie Haarlem and planned to be our largest conference to date, we faced a race against time to reorganize as the global Covid-19 pandemic took hold.

Initially set for April 2020 at the Philharmonie Haarlem and planned to be our largest conference to date, we faced a race against time to reorganize as the global Covid-19 pandemic took hold.


Given the rapidly evolving situation, we made the difficult decision to reschedule the conference. Initially envisioning a physical gathering, we soon realized the pandemic's unpredictable nature made planning precarious. Subsequently, we pivoted towards creating a fully virtual conference.

While none of us had prior experience in this domain, and despite enduring periods of doubt and uncertainty, we deemed ICPR 2020 a resounding success. Attracting nearly 1,400 attendees from around the world, and featuring three days of simultaneous tracks, all orchestrated seamlessly from a single base in Amsterdam, we marveled at our technical adaptability in pulling off such an event.

Distinguished speakers like Michael Mithoefer, Janis Phelps, Wade Davis, and Katrin Preller left a lasting impression, along with thought-provoking discussions on critical topics such as diversity, equity, and access in psychedelic medicine, as well as the medicalization and mainstreaming of psychedelics. The ability to engage in post-event discussions fostered a sense of community, particularly during a time when many were isolated or in small groups. The digital format enhanced accessibility and significantly reduced our carbon footprint, allowing us to easily record talks for YouTube. As the pandemic subsided, we began contemplating ways to revisit the original plans that had been temporarily set aside.

ICPR 2022

A groundbreaking event in the realm of psychedelics, exceeded all expectations with an impressive turnout of over 1,200 enthusiastic attendees.
The gathering featured giants in the field, including Paul Stamets, Bill Richards, and David Nichols, among other luminaries.
Hosted over three captivating days, the event unfolded at the prestigious Philharmonie venue in Haarlem, Netherlands. This iconic location provided an inspiring backdrop for discussions, presentations, and exchanges that pushed the boundaries of psychedelic research, therapy, and consciousness exploration. Notably, ICPR 22 marked a significant post-pandemic milestone in the psychedelic journey, fostering collaboration and propelling the field into a promising future of discovery and understanding.

ICPR 2024

At ICPR 2024, the stage was set by the Minster of Healthcare from the Netherlands, Pia Dijkstra who spoke to the pressing need for innovation in mental health therapeutics and that more research into psychedelics is needed to explore this potential. In the following 3 days, over 1,100 researchers, therapists, policymakers, entrepreneurs and enthousiasts came together to fulfil the purpose of ICPR 2024. That is, to gather and facilitate conversation and connection between open-minded, committed, curious, and caring individuals whose collective perspective creates a critical and constructive narrative for what psychedelics mean moving forward in 21st-century Europe.

Those who went for the full ICPR experience kicked off with pre-ICPR events on the day before the conference: “Pathways to Access Summit” and “Workshops on Psychedelic Therapy”.

The OPEN Foundation is honored and humbled by the ICPR 2024, the progress in the field of psychedelic research and therapy, and what lies ahead. And gratitude, for our co-creation, persists. Fortunately so, as it’s our fuel to do our part in this ongoing process of integrating psychedelics safely and responsibly into healthcare and society.

See you in 2026!
