Program on Psychedelics, Spirituality, and Religion (2021-2026)
Over the past several years, the Center has been privileged to convene an extraordinary community of scholars, researchers, practitioners, artists, students, and staff whose collective efforts have helped establish the CSWR as a leading institutional home for serious and sustained engagement with this rapidly evolving field.
We extend our deep gratitude to all who contributed to this work, and especially to Jeffrey Breau and Paul Gillis-Smith, who first joined this initiative as students and then, over the course of two years (2024–2026), provided dedicated leadership in shaping its final programmatic phase.
We also extend our gratitude to our close collaborators and partners, especially the Petrie-Flom Center for Health Law Policy, Biotechnology, and Bioethics at Harvard Law School, the Mahindra Humanities Center at Harvard, and the Office of Ministry Studies at Harvard Divinity School, whose partnership helped deepen and expand this work across Harvard.
The CSWR's long-running engagement with psychedelics and spirituality began with the widely popular "Psychedelics and the Future of Religion" series and expanded to include reading groups, workshops, public scholarship, art exhibitions, digital initiatives, and annual conferences. Most recently, the program matured into a comprehensive, multi-pronged initiative within the broader Harvard Study of Psychedelics in Society and Culture, advancing research on psychedelic chaplaincy, fostering interdisciplinary research communities, and expanding public discourse around psychedelics and religion.
The program had three primary goals: (1) to advance research on psychedelic chaplaincy; (2) to increase public awareness of pressing topics in the study of psychedelics and religion; and (3) to convene a scholarly community around the psychedelic humanities. In service of these goals, the program and affiliates developed a psychedelic chaplaincy training program, supported five multi-year research initiatives, produced over 22 publications, hosted two dozen public events, and organized four, interdisciplinary Psychedelic Intersections conferences.
A review of the program's accomplishments and primary initiatives can be found below.
Psychedelic Chaplaincy
Tending the Spiritual in Psychedelic Care Workshops
The Tending the Spiritual workshops provided attendees with a broad overview of approaches to spiritually responsive care tailored to psychedelic settings. This program was featured in the Harvard Gazette, which provides more information about the pilot workshops and vision of the program.
Our September workshop focused on spiritual care training for psychiatrists, MDs, chaplains, and researchers working in clinical psychedelic settings. The December workshop focused spiritual care training for church leaders, harm reduction specialists, lawyers, and caregivers working in community psychedelic settings. More information about September is available here and additional information about December can be found here.

Landscape Analysis: Spiritual Care and Psychedelic Facilitation
In the summer of 2025, the CSWR released “Psychedelic-Assisted Therapy Training in the US: A Landscape Analysis” preprint, which was published by the journal PLOS One in May 2026.
Commissioned by the CSWR and conducted by leading experts Roman Palitsky, MDiv, PhD (Emory Spiritual Health, Woodruff Health Sciences Center and Department of Psychiatry and Behavioral Sciences, Emory University School of Medicine) and Caroline Peacock, LCSW, DMin (Emory Spiritual Health and Winship Cancer Center Institute), the report’s findings are based on 13 established and emerging psychedelic facilitation training programs and presents the first detailed systematic analysis of both growing strengths and notable gaps in spiritual, existential, religious, and theological (SERT) care training.

Workshop Analysis: Tending the Spiritual Workshops
In May 2026, the CSWR released “Tending the Spiritual Workshops: Development, Evaluation, and Autoethnographic Assessment of Lessons learned,” a report outlining the structure and pedagogy of the Center's Tending the Spiritual workshops, as well as lessons learned from these efforts.
Commissioned by the CSWR and conducted by leading experts Roman Palitsky, MDiv, PhD (Emory Spiritual Health, Woodruff Health Sciences Center and Department of Psychiatry and Behavioral Sciences, Emory University School of Medicine) and Caroline Peacock, LCSW, DMin (Emory Spiritual Health and Winship Cancer Center Institute), the report’s findings are based on an auto-ethnographic assessment conducted by the four workshop leads (Roman Palitsky, Caroline Peacock, Jeffrey Breau, and Paul Gillis-Smith).
Psychedelic Intersections Conference
Psychedelic Intersections was the CSWR’s flagship conference on the study of psychedelics and spirituality. The conference was founded by Jeffrey Breau and Paul Gillis-Smith in 2023 and grew into an annual conference hosted by the CSWR.
Together, the four events convened over 100 interdisciplinary scholars, practitioners, and policymakers working at the intersection of psychedelics and the humanities. They featured keynote presentations from Rick Doblin, Leonard Pickard, Carl Hart, Luis Eduardo Luna, Marian Goodell, Elías García Méndez, Ramzi Fawaz, Benjamin Breen, and Noah Feldman.
Recordings from each year are available below.
Research and Publications
The psychedelics program supported five multi-year research initiatives:
1) Indigenous Medicine and Psilocybin Mushroom Rituals in Mesoamerica (Osiris González Romero): This project analyzed Indigenous medicine, especially psilocybin—a classic psychedelic or serotonin agonist that preferentially activates the 5-HT2A receptor subtype—which can enhance symbolic behavior, promote collective rituals, and amplify synchronicity.
2) Sacred Plant Medicines of the Muysca of Suba (Paola Andrea Sánchez-Castañeda): This ethnographic project focused on the use of sacred plant medicines by the Muysca community of Suba, an urban Indigenous community in Bogotá, Colombia.
3) Novel Psychedelic Spiritual Communities (Jeffrey Breau): This multisite ethnography investigated new religious movements that use psychedelics in the U.S. to examine how novel psychedelic churches form, navigate legal frameworks, address safety, and better understand how psychedelics are reshaping religion and religious freedom in North America.
4) Saint Children, Psilocybin, and Epistemic Rupture (Paul Gillis-Smith): This project followed María Sabina’s insistence that psilocybin-containing fungi have lost their force given their use by foreigners by drawing from the records of the Wassons as “patient zero,” implicated in Sabina’s fungal prognosis.
5) Psychedelic and Ketamine Chaplaincy (Jeffrey Breau, Paul Gillis-Smith, Tara Deonauth): This clinical research program developed the practice of ketamine integration chaplaincy and investigated new approaches to psychedelic chaplaincy.

Reading Groups and Workshops
The CSWR hosted a variety of reading groups and workshops, examining psychedelics and research related to them through decolonial, archival, devotional, and aesthetic prisms, among others. Find the catalogue of these groups and their reading lists below.
Are psychedelics going to save religion? What ethical and moral questions surround psychedelic use, especially for substances which have roots in ancient or indigenous traditions? Who gets to decide what is real vs. hallucination—and how do psychedelics challenge our answers?
Organized and facilitated by Jeffrey Breau and Paul Gillis-Smith, then 3rd-year Master of Divinity students.

Led by CSWR Visiting Scholar Christine Hauskeller, this series of six workshops explores the intersection of decolonial theory and psychedelic ethics. We will examine power dynamics within the evolving field of psychedelic studies, focusing on conflicts between diverse knowledge systems and practices. Beginning with an overview of decolonial concepts, we'll progress through critical analyses of clinical research, aesthetic representations, and the commodification of psychedelic experiences. The final sessions will focus on those objectified by colonizing practices in the psychedelic space namely plants and animals, indigenous groups, and underground practitioners.
Adopting a Decolonial Lens: Rethinking Psychedelic Ethics
This opening session will provide a comprehensive overview of decolonial approaches to psychedelic ethics, why it matters and the current state of discussion in psychedelic studies. We will explore key concepts from decolonial theory and their application to psychedelic studies, reading the open-access article "Decolonization is a metaphor towards a different ethic. The case from psychedelic studies" (Hauskeller et al. 2022).
Readings:

- Hauskeller C. et al. 2022, Decolonization is a Metaphor for a Different Ethic.
The Power of Knowledge – Decolonizing the Clinical Gaze
The medical sector is a powerful institution in contemporary society. The way in which psychedelics are currently filtered through scientific processes and procedures is creating a specific kind of expertise and knowledge. However, the medicalization of psychedelics can also be read as a contradiction in terms. The session will discuss how the standardization of psychedelic experiences in clinical settings can be seen as a form of colonization, potentially erasing or delegitimizing other ways of knowing. We will analyze the ongoing debates within clinical teams about standards for researching these substances and experiences. Recommended preparatory reading includes the relevant chapter in the book "Philosophy and Psychedelics."

Aesthetics and Experience: Decolonizing Psychedelic Representations
The workshop will examine the commodification of psychedelic art and its potential impact on individual experiences. We explore the sensory and aesthetic dimensions of psychedelic experiences and their ethical implications. We discuss two contrasting perspectives: first, the possible molding or alienation of experiences through research designs and questionnaires; second, the impact of artistic representations of psychedelic experiences on public perceptions and expectations. We will also address the ethical responsibilities in communicating about psychedelic experiences, particularly in therapeutic contexts where unmet expectations can lead to distress. The session will touch on historical perspectives, such as Herbert Marcuse's views on psychedelics' potential for social change and consider how these ideas relate to contemporary psychedelic culture.

Respecting Nature - Relationships with Plants and Animals in Psychedelic Cultures
This workshop examines the ethical implications of bioprospecting and commodification of psychedelic plants and animals. We will explore concepts like Terra Nullius and the "doctrine of discovery" that have historically justified the appropriation of natural and indigenous resources. We will explore how the medicalization and commercialization of psychedelics often exploit nature and discuss the institutional systems that have been designed to secure this power relation, such as patent laws and intellectual property regimes continuing colonial patterns of domination. Yet, there are also new forms of cultivation and economic relations emerging, for instance in peyote farming. We'll consider tensions between indigenous and Western engagements with nature and address "natural" versus "synthetic" substances in psychedelic research.

Respecting Indigenous Knowledges and Practices in the Commodification of Psychedelics
This workshop focuses on the complex intersections between the rich and diverse indigenous uses of psychedelics and Western interests. Past actions from the colonial powers in the Americas prosecuting peyote-using women in the 1500s to the transactions Gordon R Wasson conducted with Maria Sabina, exploitation and oppression seem to shape transcultural encounters. The contemporary psychedelic tourism industry is another problematic case in point. In this session we'll discuss the ethical considerations surrounding the use of traditional knowledge in modern contexts, and the role of another set of dualism, namely "scientific" versus "traditional" and "spiritual". We'll also address the right of refusal and the importance of indigenous control over research involving their practices and knowledge. In recent developments indigenous scholars and practitioners discuss how they can ethically share their expertise and practices and thus remodel the power dynamics between Western and indigenous knowledge holders concerning psychedelics.
Countercultural Expertise: The Role of Psychedelic Subcultures
Our final workshop delves into the rich history and knowledge base of psychedelic subcultures, examining how these communities have developed their own forms of expertise outside mainstream institutions. We will explore the validity of experiential knowledge in psychedelic contexts, such as that of experienced ravers. We will explore how the current "psychedelic renaissance" relates to earlier waves of Western interest in psychedelics, and how subcultural knowledge is often marginalized in the push for medicalization and professionalization. The session will examine the tension between the individualized, commodified approach to psychedelics in much current research and the more communal, spiritual, or countercultural approaches found in many subcultures. We'll discuss how to acknowledge and respect diverse forms of psychedelic knowledge and practice without falling into problematic dualisms or perpetuating colonial power structures.
This reading group was organized and facilitated by Tristan Angieri, then MTS student at Harvard Divinity School. How does psychedelic experience influence the perception of art and beauty? What role does aesthetics play in the psychedelic experience, and how does it impact ethical considerations? This reading and learning group will explore these questions and more, focusing on the relationship between psychedelics, aesthetics, and ethics.

The Psychedelics Beyond Psychedelics reading group was organized and facilitated by Emily Lippold-Cheney (MDiv II), Paula Ortiz (MDiv III), and Lila Rimalovski (MDiv II). The reading group explored the ways in which psychedelic experiences without ingestion of psychedelic substances might offer the field of Psychedelic Studies a holistic and just approach to transcendence, healing, and divine connection. In doing so, we sought to engage across disciplines in order to weird, queer, and transcend the definitions and frameworks that we may have consciously and unconsciously imposed upon our understanding of what is and isn’t “psychedelic.” We examined modalities of transcendence–such as sound, childbirth, divination, and clowning–to explore capacities, practices, and potentials that are core to human and non-human cultures. We brought these topics into conversation with the psychedelic humanities by bringing the ideas they offer to the current landscape of the field, while using frameworks core to Psychedelic Studies in our examination of these topics (e.g. set and setting, medical ontologies).

This workshop explored the Ludlow-Santo Domingo Library, the world’s largest collection of psychedelic literature, housed at Harvard. It was organized and led by Andrew Green Hannon.
This workshop was designed to support your own encounter, engagement, and exploration with the archive and its materials. The group's explorations were informed by a commitment to multiple ways of knowing: textual, sociological, experiential, and material.
The Ludlow-Santo Domingo collection is extraordinary in its breadth—both geographic and temporal—and in the multitude of religious traditions seen through the lens of drugs. This resource has been at Harvard for some time, but large swaths of it remain virtually untouched. It has within it materials that range from the new religious movements inspired by psychedelia, including Timothy Leary League for Spiritual Discovery, electronic neo-shamanism of the turn of the twenty-first century, and the contemporary enthusiasm for ayahuasca, to accounts of the religious traditions of the peoples of the Americas around the time of European contact, and the records of colonialism and suppression of Indigenous religious practices. There are also materials from India, Tibet, Nepal, and North Africa, as well as from Jewish and Muslim religious traditions.
Dr. Hannon holds a PhD in American Studies from Yale University. He has taught history, American Studies, and labor studies at UMASS Boston and Emerson College. His research focuses on performance and politics in the American Counterculture. He is the chief curator of the forthcoming 2027 exhibit, “Let's Take a Trip Together: A Long History of Psychedelics,” at the Houghton Library.
The workshop looked at practical questions of the archive:
- How do you find archives you are interested in?
- How do you search online to find aids and databases, and what are the limitations of those tools?
- How do you authenticate objects and think about the limitations of sources?
The workshop also explored philosophical questions about archival work:
- What is an archive?
- What are the ethical issues raised by encountering trip reports, childhood drawings, and psychological profiles?
- What is the role of class in the creation and maintenance of objects in the historical record?
