Increase Your Knowledge of Ayahuasca

The Information That Matters

Sample subtitle here

I knew absolutely zero about ayahuasca before I started drinking it. I wish I’d had more guidance and information in those early months and years as I stepped into this world.

Through my personal ceremony experiences and my research activities, the more I’ve learned about ayahuasca – its origins, and the communities and cultures in which it’s used – my relationship with it has become increasingly rich, meaningful, and humbling.

The top books on psychedelics may or may not include information about ayahuasca, and there’s a lot of confusing, misleading, and overly romanticized information about ayahuasca online. I’m aiming to offer a helpful and healthy alternative here with a few credible resources. I hope they spark clarity or inspiration, support your or someone else’s ayahuasca journey, aid you in informed decision-making, or help you feel less alone.

You can start with my free resource, 9 Ayahuasca Tips for Optimizing Your Ceremonies.

Organizations promoting safety, research, inclusion, and respect for ayahuasca’s origins

ICEERS

iceers.org

The International Centre for Ethnobotanical Education, Research, and Service (ICEERS) is “a non-profit organization dedicated to navigate the challenges of the globalization of Traditional Indigenous Medicines.” ICEERS offers information, support, advocacy, research, and community-building resources. They’ve compiled statistics on global ayahuasca use, and offer an abundance of reliable information about ayahuasca and other plant medicines, including iboga and cannabis.

Chacruna

chacruna.net

Chacruna is an organization that offers educational programs on plant medicines, conducts research, hosts conferences, and generally is a progressive and credible resource in the psychedelic space. Their mission is to “promote reciprocity in the psychedelic community, and support the protection of sacred plants and cultural traditions. We advance psychedelic justice through curating critical conversations and uplifting the voices of women, queer people, Indigenous peoples, people of color, and the Global South in the field of psychedelic science.” 

I’ve attended several of Chacruna’s excellent educational offerings, including workshops, discussions, and a 14-week course entitled Ayahuasca Healing, Science and Indigenous Knowledge.

Chacruna provides a range of online articles, but one of their most important publications is the Ayahuasca Community Guide for the Awareness of Sexual Abuse.

What We Learned

Our research with Western ayahuasca ceremony leaders

Meeting the medicine halfway

Callon, C., Williams, M., & Lafrance, A. (2021). The Journal of Humanistic Psychology, 1–27.

Ayahuasca ceremony leaders described preparation and integration practices they consider helpful for ensuring safe and productive experiences for ceremony participants. 

Ceremony leaders’ perspectives on the good, the bad, and the ugly of ayahuasca drinking in ceremonial contexts

Williams, M., Crotty, S., Callon, C., & Lafrance, A. (2022a). The Journal of Transpersonal Psychology, 54(2), 141–167.  

Ayahuasca ceremony leaders offered their perspectives on facilitative ceremony conditions, contraindications for drinking ayahuasca, and psychedelic emergencies. An inventory of every concern related to ceremonial ayahuasca use mentioned by the leaders is also presented. 

Getting to the root

Williams, M., Kingston Miller, A., Loizaga-Velder, A., Files, N., & Lafrance, A. (2022b).  Journal of Psychoactive Drugs. Advance online copy.

Ayahuasca ceremony leaders provided their conceptualizations of eating disorders and the potential therapeutic mechanisms of action of ayahuasca for individuals living with them. 

Ayahuasca ceremony leaders’ perspectives on special considerations for eating disorders

Williams, M., Kingston Miller, A., & Lafrance, A. (2024). Eating Disorders: The Journal of Treatment and Prevention, 32(2), 120–139.

Ayahuasca ceremony leaders shared their perspectives on screening for eating disorders, the role of purging and dietary restrictions, potential risks, and how ayahuasca might complement conventional eating disorder treatment. We proposed that considering Indigenous approaches could evolve conventional models of eating disorders treatment, and that collaborations might be best invited in a decolonizing, bidirectional process bridging Western and Indigenous healing paradigms.
