Psychedelic Science, Contemplative Practices, and Indigenous and Other Traditional Knowledge Systems: Towards Integrative Community-Based Approaches in Global Health

As individuals and communities around the world confront mounting physical, psychological, and social threats, three complimentary mind-body-spirit pathways toward health, wellbeing, and human flourishing remain underappreciated within conventional practice among the biomedical, public health, and policy communities. This paper reviews literature on psychedelic science, contemplative practices, and Indigenous and other traditional knowledge systems to make the case that combining them in integrative models of care delivered through community-based approaches backed by strong and accountable health systems could prove transformative for global health. Both contemplative practices and certain psychedelic substances reliably induce self-transcendent experiences that can generate positive effects on health, well-being, and prosocial behavior, and combining them appears to have synergistic effects. Traditional knowledge systems can be rich sources of ethnobotanical expertise and repertoires of time-tested practices. A decolonized agenda for psychedelic research and practice involves engaging with the stewards of such traditional knowledges in collaborative ways to codevelop evidence-based models of integrative care accessible to the members of these very same communities. Going forward, health systems could consider Indigenous and other traditional healers or spiritual guides as stakeholders in the design, implementation, and evaluation of community-based approaches for safely scaling up access to effective psychedelic treatments.
