Indigenous Knowledge Systems & Psychedelic Science: Towards Ethical and Reciprocal Collaboration.

Indigenous Peoples have long stewarded natural psychoactive medicines through ceremony and kinship, yet their contributions are often marginalized in psychedelic science. This commentary argues for reciprocal collaboration grounded in Indigenous sovereignty, cultural rights, and governance. Drawing on traditions involving ayahuasca, psilocybin, peyote, and iboga, it illustrates how Indigenous methodologies offer critical insights for safety and efficacy. The authors call for embedding free, prior, and informed consent, equitable benefit-sharing, and Indigenous leadership in research and policy, moving beyond tokenism toward systemic change. They conclude by urging formal, transparent convening processes modeled on WHO global consultations to bring Indigenous leaders, researchers, and policymakers together.

Abstract

Indigenous Peoples have cultivated and protected natural psychoactive medicines through ceremony, kinship, and spiritual responsibility across generations, yet their long-standing contributions have often been marginalized through extractive research, commercialization, and policy exclusion. It is Indigenous communities that have stewarded and gained expertise working with psychoactive medicines for centuries, yet they remain underrepresented within the scientific discourse. This commentary advances the case for reciprocal and equitable collaboration in psychedelic science, grounded in Indigenous sovereignty, cultural and intellectual property rights, and governance. Drawing on traditions involving ayahuasca, psilocybin, peyote, and iboga, we illustrate how Indigenous methodologies, including ritual, community-based practices, and ecological approaches, offer insights critical to both safety and efficacy. We argue that research and policy must embed free, prior, and informed consent, equitable benefit-sharing, and Indigenous leadership. Such efforts require moving past tokenistic inclusion toward meaningful collaboration and systemic change in psychedelic research that is both scientifically rigorous and culturally just. We conclude by calling for more formal, transparent, and globally legitimate convening processes, such as those modeled on WHO global consultations, that can bring Indigenous leaders, researchers, and policymakers together in dialogue. These steps represent profound acts of inclusion essential for these medicines to realize their full potential to heal and transform.
