Open Psychedelic

Evaluation Nexus


OPEN is an interdisciplinary, community-wide, non-commercial research and evaluation effort. We aim to measure the impact of state legal psychedelic services. 

OPEN is housed at Oregon Health and Science University (OHSU): Our members are clinicians,  teachers, and researchers who are dedicated members of the  community. 

We have three main aims:

1) Create useful tools and software. These user-friendly tools will help gather information about the effects of psychedelic service provision.

2) Grow a network of participating Training Centers, Service Centers, and Facilitators. By sharing information, our members help one another learn and grow.

3) Share findings to improve service safety, quality, and equitable access. We publish results in scientific journals and also share feedback with Training and Service Centers.


The purpose of OPEN  research is to advance public health and collective wisdom: We have no financial conflicts of interest. We adhere to the highest standards of research ethics and data security. OPEN’s diverse Community Advisory Council informs the work and ensures accountability.

Current Projects

OPEN has a diverse set of research projects, all of which are focused on assessing safe, meaningful, and equitable psychedelic services. Currently, our work is funded by federal agencies and OHSU. We can also accept unrestricted gifts through the OHSU Foundation.

Adverse Events Reporting:

OPEN’s Adverse Event Portal creates a public-facing system for anonymous reporting of adverse events related to psilocybin use in Oregon. Systematically collecting information about adverse events from multiple sources may allow us to detect patterns and improve safety. 

Measure 109 Workforce Survey: 

This project seeks to understand the emerging psilocybin services workforce. This survey assesses the facilitator training landscape and surveys graduates about their training experiences and practice intentions.  This baseline knowledge will help inform facilitator training program curriculum development and identify workforce gaps.

Harm Reduction Study: 

This study is interviews psychedelic harm reduction experts, adults considering psilocybin use, and mental and physical healthcare providers to understand best practices for reducing the risks of psychedelic use and identifies key messages for educational strategies to prevent harms.

Non-Profit Client Experiences Repository  

The purpose of OPEN’s non-profit client experiences repository  is to assess the impacts of legal psychedelic services. By building a collaborative interstate research network and confidentially documenting client experiences, this project supports the safety, equity, and quality of supervised psychedelic experiences. Rigorous assessment and transparent reporting advance understanding of how well state level initiatives are working, and how to improve them. This project thoughtfully balances large-scale public health information with individual client privacy and confidentiality.

Delphi Project to Develop Expert Consensus on Psilocybin Services Outcomes:

Because psychedelic services are so novel, we don’t yet know how to define “safe” or “high-quality” services. The goal of the Delphi project is to establish the first standardized package of measures which define the safety and quality of supported psychedelic services. This tool can be integrated across the service center ecosystem to enable harmonized data collection. It will allow comprehensive monitoring of safety, effectiveness, and equitable implementation of psychedelic services.
