DEA Advances Psilocybin Rescheduling

A Petition is advanced for rescheduling psilocybin from schedule I to schedule II

This is a historic step forward and a major milestone in the movement to expand access to Psychedelic-Assisted Care (PAC)


On August 11, 2025, the U.S. Drug Enforcement Administration (DEA) advanced a petition on behalf of Dr. Sunil Aggarwal and the Advanced Integrative Medical Science Institute (AIMS) by the National Psychedelic Association’s Advocacy Director, Kathryn Tucker along with co-counsels Matt Zorn and Shane Pennington, to reschedule psilocybin from Schedule I to Schedule II. The petition is now under review by the U.S. Department of Health and Human Services (HHS), which will conduct a scientific and medical evaluation.

This action represents the most significant step yet in recognizing psilocybin’s therapeutic potential, particularly for patients suffering from conditions such as treatment-resistant depression, PTSD, and end-of-life anxiety.

The Journey To Get to This Point

  • February 2022

    The petition to reschedule psilocybin submitted to DEA.

  • October 2023

    Aggarwal v. DEA: The Ninth Circuit Court of Appeals rules that the DEA mishandled the petition, requiring reconsideration.

  • February 2025

    The DEA advises it is preparing to transmit the petition to HHS, requesting updated evidence bearing on the petition.

  • August 2025

    The DEA formally transmits the petition to HHS, triggering scientific review.

Why This Matters

Rescheduling psilocybin would represent a paradigm shift in U.S. drug policy:

  • Opening pathways for compassionate clinical use under medical supervision
  • Providing legal protection for patients and providers under Right-to-Try laws
  • Supporting at home treatment for Veterans, cancer patients, and those with treatment-resistant conditions

The National Psychedelics Association (NPA) is proud to be at the forefront of this breakthrough.
