Background
Over the past year, several licensees have shared concerns regarding psilocybin products with high psilocin content being used for lower dose administration sessions.
In response to this concern, OPS will convene two Psilocybin Product Potency Workgroup meetings in March, 2026.
All licensed psilocybin manufacturers and laboratories are invited to attend and there will be a public comment period to receive input from members of the public including other licensees. Oregon Environmental Laboratory Accreditation Program (ORELAP) will also participate, and OPS will facilitate the meetings.
The workgroup will consider potency formulas for psilocybin products, including “total psilocybin equivalent" and identify safety issues related to the use of high-psilocin products. We will review available high-quality peer reviewed research that addresses psilocin to psilocybin ratio or other values that represent unsafe thresholds for subperceptual doses.
This workgroup is not a part of a rulemaking process, but it may produce recommendations that will inform
OPS rulemaking in 2026.
