How Should We Measure Safety and Quality in Supervised Psilocybin Services?
As supervised psilocybin services expand in Oregon, Colorado, and other settings, researchers and policymakers face an important question: how do we know whether these services are safe, ethical, and helpful? A recent study published in the Journal of Psychopharmacology developed psilocybin safety measures and OPEN consensus measures to help assess the quality, safety, and outcomes of community-based psilocybin services.
The study was conducted through the Open Psychedelic Evaluation Nexus, or OPEN, a practice-based research network focused on evaluating psychedelic services in real-world community settings. The research team included Jason B. Luoma, PhD, from Portland Psychotherapy Clinic, Research, & Training Center, along with colleagues from Oregon Health & Science University, Legacy Research Institute, Sequoia Center, Portland State University, and other organizations.
Why Measurement Matters
Legal psilocybin services are emerging faster than the research base needed to evaluate them. Oregon and Colorado have authorized community-based psilocybin services, but these models are different from clinical trials and traditional medical care. In community settings, people may seek psilocybin services for many reasons, including depression, anxiety, trauma, spirituality, end-of-life distress, general well-being, or personal growth.
Because these services are new, there has not been a standardized way to track whether they are being delivered safely or effectively. Without shared measures, service centers, regulators, and researchers may struggle to compare outcomes, identify risks, or improve care over time.
How the Study Worked
The researchers used a three-phase e-Delphi process, a structured method for gathering expert consensus. The study included 36 experts with at least five years of experience supporting psilocybin experiences or other relevant psilocybin expertise. These experts came from diverse backgrounds, including ceremonial settings, Indigenous practices, clinical trials, underground services, and psilocybin science.
In the first phase, experts suggested possible measures of high-quality psilocybin services. In the second phase, they rated these measures for importance and feasibility. In the third phase, qualitative interviews helped refine and prioritize the most useful measures.
The result was a set of consensus measures focused on three broad areas: process, outcomes, and structure. Process measures describe how services are delivered. Outcome measures assess what happens to clients after services. Structure measures focus on the service center environment, policies, and organizational supports.
What Experts Prioritized
One of the strongest themes was safety. Experts repeatedly emphasized the importance of informed consent, clear boundaries around touch and sexual contact, and careful preparation before psilocybin administration. They also highlighted the need to assess medical and mental health history, medication interactions, prior psychedelic experience, client expectations, support systems, and plans for integration.
The study also proposed safety checklists for facilitators and clients. Facilitator checklists included items such as physical injury, emergency service use, premature departure from the site, aggressive behavior resulting in injury, death, and other safety events. Client checklists included questions about boundary violations, new medical visits, persistent headaches, nausea, worsened anxiety or depression, increased suicidal thoughts, and other challenging experiences.
Beyond Symptom Reduction
Another important finding was that high-quality psilocybin services may not be measured only by changes in depression or anxiety. Experts also prioritized outcomes such as whether clients’ goals were met, whether the experience felt personally meaningful, whether well-being improved, and how clients rated the overall safety and quality of the service.
This is important because community-based psilocybin services are not always sought as medical or psychological treatment. People may seek them for existential, spiritual, or other personal reasons. A good measurement system needs to capture both potential harms and potential benefits without assuming that every client has the same goals.
Implications for Policy and Practice
The study suggests that service centers, policymakers, and researchers need practical tools for monitoring psilocybin services as they expand. Standardized measures could help identify safety concerns, improve training, guide regulation, and support equitable access. They could also help service centers evaluate their own practices and make improvements over time.
The authors note that these measures will need further testing in real-world settings. However, the study provides an important starting point for building accountability into a rapidly developing field.
Moving Forward
As supervised psilocybin services continue to grow, shared standards will be essential for protecting clients and improving care. The OPEN consensus measures offer a practical framework for tracking client experiences, service quality, and potential risks across community settings. By using clear psilocybin safety measures, the field can move toward a more transparent, ethical, and evidence-informed approach to psilocybin services.
