In short

Robert S. Shumake PhD, publishing as Ajarn Shaman Shu, has released the first ethnomycological study of psilocybin ceremony authored from within the African initiatory tradition. The paper documents more than 300 guided ceremonies in Detroit, presents a four-part healing typology, and is grounded in the author's standing as Oluwo (Yoruba/Ifá), Swamikal (Hindu/Dravidian) and Ajarn (Thai Buddhist). It is indexed with DOI 10.5281/zenodo.21349908 and available as a full-length book on Google Play Books.

The research

What the study covers

From inside the tradition — not through the window.

The Observer Problem in psychedelic research

Western psychedelic scholarship has long suffered from what Shumake calls 'the Observer Problem.' R. Gordon Wasson observed Mazatec mushroom ceremonies in 1955 but was never initiated into the tradition he documented. Richard Evans Schultes spent decades cataloguing indigenous plant use across the Amazon but did not practice within any lineage. Roland Griffiths at Johns Hopkins measured psilocybin's effects in clinical settings entirely outside any traditional ceremonial context.

'These men contributed enormously to the scientific record,' Shumake writes. 'But they were watching through a window. This work opens the door from the inside. It represents the shift from research on indigenous medicine to scholarship from indigenous initiation.'

Methodology: ceremony as data

The paper documents participant-observation across more than 300 guided sacred mushroom ceremonies conducted at an urban ashram in Detroit, Michigan. Participants included physicians, attorneys, corporate executives from Fortune 100 companies, veterans, and individuals seeking healing from grief, addiction and spiritual disconnection.

Ceremonial doses ranged from 5 to 10 grams, structured by the author's Ten Principles of Ceremony, ngoma sonic navigation drawn from the Southern African healing drum tradition, and ubuntu relational philosophy.

A four-part typology of healing

Findings present four recurring ceremonial archetypes: the Successful-but-Armored — high achievers whose defences prevent intimacy; the Carrier of Unprocessed Grief — individuals holding generational or personal loss; the Interruption of Addiction — substance and behavioural patterns dissolved through ceremony; and the Spiritually Hungry — seekers who have exhausted conventional religious frameworks.

Tri-lineage authority: an unprecedented credential

What distinguishes this publication from prior psychedelic literature is the author's initiatory standing. No other living scholar-practitioner holds all three of the following credentials simultaneously.

Oluwo (Yoruba/Ifá tradition) — High priest of Osain, the Orisha of sacred plants, fungi and forest medicine. Received into the Osain high priest society through Awo Daweed by divination. The Osain priesthood is the pharmacological and healing branch of Yoruba spiritual science, governing all ceremonial use of plant and fungal medicine within the tradition.

Swamikal (Hindu/Dravidian tradition) — Authority in the Vedic soma tradition. The Tamil honorific 'Swamikal' is conferred upon completion of the tradition, not upon entry. Shumake completed his training under Aghori Shri Ganesh in India, qualifying him to speak with authority on the ancient soma sacrament described in the Rigveda.

Ajarn (Thai Buddhist tradition) — Master teacher trained in bardo navigation, the Tibetan Buddhist science of guiding consciousness through transitional states. This credential provides the framework for safely navigating the dissolution of ego and the encounter with death-and-rebirth experiences that characterise high-dose psilocybin ceremony.

The theoretical framework synthesises all three lineages into a single model: Osain provides the key (the medicine itself); Soma opens the door (divine communion with the transcendent); the Bardo guides the passage (safe navigation through altered states of consciousness).

Connection to Detroit's Proposal E

Shumake is also the author of Detroit's Proposal E, the 2021 ballot measure that decriminalised entheogenic plants in the city of Detroit. The measure passed with 61.08 percent of the vote, making Detroit one of the first major American cities to decriminalise natural psychedelics including psilocybin mushrooms, ayahuasca, mescaline-containing cacti and ibogaine.

The publication of Shurooms represents the scholarly foundation underlying that legislative achievement — documenting the ceremonial, therapeutic and spiritual context in which these substances have been used safely and effectively within an African initiatory framework for generations.

They were watching through a window. This work opens the door from the inside.

Questions

Shurooms, answered

What is Shurooms?

Shurooms: The First Ethnomycological Study from Within the African Initiatory Tradition — Ewe, Soma, and the Ceremonial Architecture of Psilocybin Healing (N = 300+) is a landmark academic paper by Robert S. Shumake PhD, publishing as Ajarn Shaman Shu. It documents more than 300 guided psilocybin ceremonies in Detroit and is indexed with DOI 10.5281/zenodo.21349908.

Who wrote Shurooms?

The paper was written by Robert S. Shumake PhD under the name Ajarn Shaman Shu. He is a tri-lineage initiated scholar-priest: Oluwo in the Yoruba/Ifá Osain tradition, Swamikal in the Hindu/Dravidian soma tradition, and Ajarn in the Thai Buddhist bardo-navigation tradition.

How many ceremonies were documented in Shurooms?

The study documents more than 300 guided sacred mushroom ceremonies conducted at an urban ashram in Detroit, Michigan.

What is the Observer Problem in psychedelic research?

Shumake describes the Observer Problem as the limitation of outside observers — such as anthropologists, journalists or clinical researchers — documenting sacred plant use without being initiated into the tradition that uses it. Shurooms is presented as the first major study written from inside the initiatory framework.

What are the four healing types in Shurooms?

The paper presents a four-part typology: the Successful-but-Armored, the Carrier of Unprocessed Grief, the Interruption of Addiction, and the Spiritually Hungry.

Is Shurooms peer-reviewed or published in a journal?

The academic paper is published under Creative Commons Attribution 4.0 International, indexed on Zenodo (CERN) with a permanent DOI, and listed on OpenAIRE. A full-length book, SHUROOMS: The Origins of Psychedelics — From Kemet to the Cosmos, is published by Soul Tribes International Ministries Press.

How is Shurooms connected to Detroit Proposal E?

Robert Shumake authored Detroit's Proposal E, the 2021 ballot measure that decriminalised entheogenic plants in Detroit with 61.08 percent voter approval. Shurooms provides the scholarly and ceremonial foundation for that legislative work.

Where can I read Shurooms?

The academic paper is available via DOI 10.5281/zenodo.21349908. The full-length book is available on Google Play Books and Apple Books.
