Inaugural year of regulated psilocybin services in Oregon: safety, motivations, and utilization

Frontiers in Psychiatry May 13, 2026 Feliciano Yu, Joe Tafur, Francisco Moreno et al. 2 citations

In the first year of Oregon's regulated psilocybin program, 5,935 clients participated in 5,375 sessions. Utilization peaked in the second quarter before stabilizing. About a third of participants lived outside Oregon. The largest age group was 35–49; women and LGBTQ+ individuals were well represented, but racial diversity was limited, with White participants making up 84–92% quarterly and African American participation at 2.1%. Adverse events were rare, with behavioral and medical rates of 2.42 and 2.79 per 1,000 sessions. The program serves as both a wellness modality and an alternative for mental health distress, though racial disparities and socioeconomic barriers persist.

Willingness to participate in entheogen use research in naturalistic settings

Journal of Psychedelic Studies April 27, 2023 Riley D. Kirk, Olivia M. Uhley, Paloma Lehfeldt et al.

A survey of 84 English-speaking adults who had used entheogens in a naturalistic therapy or retreat setting in the prior five years found that nearly all (95.5%) believed entheogen research should be conducted, and 86.9% would participate in studies lasting longer than one year. More participants were willing to join remote interviews (73.5%) than in-person surveys (64.7%), and 78% said financial compensation influenced their willingness. The findings suggest that willingness to participate is not a barrier to further entheogen research.
