ARQ National Psychotrauma Centre is a leading Dutch institute specializing in the treatment and research of complex psychotrauma and PTSD, with roots in addressing the psychological wounds of World War II since 1945 and now one of Europe's foremost psychotrauma centers. ARQ is one of nine European sites conducting MAPS-affiliated clinical trials of MDMA-assisted therapy for PTSD, and integrates medication-assisted approaches including MDMA and ketamine into its high-intensity trauma treatment programs in partnership with Leiden University Medical Center.

MAPS, the Multidisciplinary Association for Psychedelic Studies, is a U.S.-based 501(c)(3) nonprofit research and educational organization founded in 1986. It works nationally and with a broader global audience to develop medical, legal, and cultural contexts for the careful use of psychedelics and marijuana. Its core activities include research, education, advocacy, and convening the field through large public events. In psychedelic medicine and policy, MAPS positions itself as an advocate for legal access, drug policy reform, harm reduction, and health equity. Its Policy & Advocacy work includes legislative advocacy, community organizing, and impact litigation, and it has also launched work on access for system-impacted people and broader health equity in the legal psychedelic ecosystem. Current documented initiatives include the Psychedelic Science conference series, the Health Equity Program, The Zendo Project, and Ask MAPS, which handles public inquiries about therapy, research, and policy reform.
