This bill introduces a new section to chapter 69.50 RCW that allows nonprofit organizations to provide psilocybin services specifically aimed at promoting wellness for military veterans and first responders. The legislation outlines the conditions under which these organizations can purchase, possess, and administer psilocybin, including requirements for licensed facilitators, participant screening, and safety protocols. Nonprofits must develop comprehensive transportation plans for participants post-administration, ensure confidentiality, and maintain detailed records of participant assessments and services provided. Additionally, the bill prohibits charging participants for psilocybin services, except for the cost of required screenings.

The bill also establishes strict guidelines for advertising psilocybin services, ensuring that no misleading claims are made and that advertisements do not target individuals under 21. Medical professionals are protected from adverse licensing actions when recommending or providing services related to psilocybin, provided they adhere to the standard of care. The legislation includes definitions for key terms such as "administration session," "facilitator," and "participant," and it includes a severability clause to maintain the act's validity even if certain provisions are found invalid.
