Integrating Psychedelic Medicines and Psychiatry: Theory and Methods of a Model Clinic

Abstract

The past two decades has seen a significant increase in both popular and scientific interest in psychedelic substances and plants as therapeutics for mental illness, addictions, and psychospiritual suffering. Current psychiatric practice privileges a biological paradigm in which the brain is considered the locus of mental illness and symptom-focused treatments are delivered to patients as passive recipients. In contrast, a psychedelic healing paradigm, constructed through examination of different ontologic understandings of plant medicines, is based on a complex multidimensional perspective of human beings and their suffering. This paradigm actively engages the sufferer in addressing root causes of illness through healing on multiple levels of existence, including spiritual and energetic domains. Numerous theoretical, methodological, and ethical challenges complicate the integration of the psychedelic healing paradigm into psychiatric practice. These include developing coherent therapeutic narratives that account for the complex processes by which psychedelic healing occurs and overcoming reductionist tendencies in the medical sciences. Tasked with overcoming such challenges, a model clinic is proposed that seeks to implement and study the psychedelic healing paradigm in a critical, interdisciplinary, and reflexive manner. Such “critical paradigm integration” would employ multimodal patient formulation and treatments, as well as a range of knowledge generation and sharing practices. Outcomes-oriented research would seek to establish an evidence base for the model, while critical dialogues would advance understandings of psychedelic substances and plants and related practices more generally. The clinic would serve as proof of concept for a new model of studying, conceptualizing, and treating mental illness.

Psychedelic Naturalism and Interspecies Alliance: Views from the Emerging Do-It-Yourself Mycology Movement

Abstract

Do-it-yourself (DIY) mycology is a movement that has emerged in the last decade in North America. DIY mycologists specialize in easy and accessible methods of mushroom cultivation and mycological experimentation and mobilize a discourse of alliance with the fungal kingdom. They draw primarily on home cultivation methods innovated by Psilocybe cultivators in the 1970s and on creative applications popularized by commercial mycologist and psychedelic enthusiast Paul Stamets in the 2000s. As a counterpoint to the newfound visibility and legitimacy of lab-synthesized psilocybin in clinical psychiatry, DIY mycology exemplifies an alternate history of this multispecies engagement. Drawing on ethnographic fieldwork in the San Francisco Bay Area and the Pacific Northwest, this chapter begins with the tacit premise of the psychedelic/entheogenic movement that the use of psychedelics fosters ecological concern. Many DIY mycologists express biocentric ethics and eco-spiritual principles, but interviews revealed a diverse and nuanced relationship to psychedelics. I argue that DIY mycology is best understood as an interspecies (or cross-kingdom) engagement that is part of an emergent ecological ethics and deep ecology worldview, one that subsumes psychedelic experiences as one manifestation of that engagement. DIY mycology exemplifies how the spread of mycological know-how, fascination, and enthusiasm has fostered an engagement with fungi that extends far beyond psychedelics. To understand this engagement, I contextualize it within wider social and cultural shifts, particularly those that reformulated our practical, ethical, and conceptual relationship with the natural world. This movement attests to the existence of multiple means to enact these ethics and to foster meaningful relationality with nonhuman life in contemporary North American society and culture.

Plant Knowledges: Indigenous Approaches and Interspecies Listening Toward Decolonizing Ayahuasca Research

Abstract

The ayahuasca research community is familiar with the concept of plant intelligences; however, they have yet to be adequately accounted for by commonly used research practices. This chapter is a call to examine the ontological and epistemological assumptions that underlie research practices and how these practices and assumptions may reinforce hierarchies of knowledge and animacy. The first part of this chapter describes some absences created by following a “methods as usual” approach when researching ayahuasca, based on ethnographic fieldwork at the World Ayahuasca Conference in 2016 (AYA2016). This highlights the need for researchers to acknowledge the methodological, disciplinary, and identity-based limitations on our abilities to produce and represent certain knowledges. Secondly, this chapter is a call to seriously and humbly engage with Indigenous sciences and epistemologies. This requires an honest reckoning with how research has contributed to colonial appropriation and marginalization of Indigenous knowledges. Indigenous ways of knowing have precedent for collaborating with teacher plants in producing knowledge and have much to contribute to discourse on multispecies perspectives. Lastly, I discuss possibilities for including multispecies sensibilities and Indigenous standpoints in research practices to create more collaborative and decolonial knowledges.

Undiscovering the Pueblo Mágico: Lessons from Huautla for the Psychedelic Renaissance

Abstract

The people of the Sierra Mazateca region of Mexico became internationally known in the 1950s for their ritual use of psilocybin mushrooms, and the Mazatec town of Huautla became a destination for mushroom seeking visitors. This chapter provides an overview of changing Mazatec and “outsider” discourses about mushrooms and the Sierra Mazateca over the last 60 years. It argues that “outsider” representations of the Sierra Mazateca and mushroom use—whether framed in terms of spiritual journeys or scientific research—tend to recapitulate some consistent patterns common to other forms of cultural tourism that owe more to the role of substances in marking distinctive cultural identities than to the effects of the substances themselves. It concludes by suggesting lessons from this history for the current moment, in which a discourse framing the use of psychedelic substances through universalizing narratives of science and individual health is becoming ascendant.

The Use of Salvia divinorum from a Mazatec Perspective

Abstract

Salvia divinorum is a medicinal and psychoactive plant endemic to the Sierra Madre Oriental of Oaxaca, Mexico. The Mazatec people have been using the leaves for centuries in ceremonies for its psychoactive properties and as a treatment for arthritis and inflammation, gastrointestinal problems, headaches, and addictions, among other uses. The active principle of Salvia divinorum, the terpene salvinorin A, is a uniquely potent and highly selective kappa-opioid receptor agonist and, as such, has enormous potential for the development of valuable medications. Among them, the most promising include safe and nonaddictive analgesics, neuroprotectors, short-acting anesthetics that do not depress respiration, antidepressants, anti-inflammatories, medications for the treatment of addiction to stimulants and alcohol, and drugs to treat disorders characterized by alterations in perception. The Mazatec consider Salvia divinorum to be a very powerful plant spirit that should be treated with utmost respect, and the preparation for the ceremony requires a strict regimen. They chew the fresh leaves at night while chanting and praying. In the Western use, the dry leaves are potentiated in extracts to be smoked. A lack of information about the appropriate doses and other considerations while smoking the extracts could result in overwhelming experiences due to the high potency and fast onset of the substance. For the Mazatec, smoking the plant is not the preferred mode. How could we create a bridge between the two perspectives? In this chapter, I will try to clarify the best ways to use Salvia divinorum for medicinal, psychotherapeutic, and inner exploration purposes.

Whole Organisms or Pure Compounds? Entourage Effect Versus Drug Specificity

Abstract

As the therapeutic use of sacred plants and fungi becomes increasingly accepted by Western medicine, a tug of war has been taking place between those who advocate the traditional consumption of whole organisms and those who defend exclusively the utilization of purified compounds. The attempt to reduce organisms to single active principles is challenged by the sheer complexity of traditional medicine. Ayahuasca, for example, is a concoction of at least two plant species containing multiple psychoactive substances with complex interactions. Similarly, cannabis contains dozens of psychoactive substances whose specific combinations in different strains correspond to different types of therapeutic and cognitive effects. The “entourage effect” refers to the synergistic effects of the multiple compounds present in whole organisms, which may potentiate clinical efficacy while attenuating side effects. In opposition to this view, mainstream pharmacology is adamant about the need to use purified substances, presumably more specific and safe. In this chapter, I will review the evidence on both sides to discuss the scientific, economic, and political implications of this controversy. The evidence indicates that it is time to embrace the therapeutic complexity of psychedelics.

Ceremonial ‘Plant Medicine’ use and its relationship to recreational drug use: an exploratory study

Background: The ceremonial use of psychoactive/hallucinogenic plant based drugs, such as ayahuasca, psilocybin and others, is a growing trend in the United States (US) and globally. To date, there has been little research documenting how many people are using psychoactive substances in this context, who the users are, what benefits/risks exist in the use of these drugs and the relationship between ceremonial drug use and recreational drug use.
In this paper we describe a cohort of plant medicine facilitators in the US and explore how they differentiate plant medicine use from recreational drug use.
Methods: Using modified ethnography, individual interviews were conducted in 2016 with 15 participants who are currently facilitating plant medicine ceremonies in the US. Descriptive content analysis was performed to discover themes and to inform a larger mixed-method study.
Results: Ceremonial drug use was seen by participants as a natural healing and treatment modality used in the context of community and ritual. Three main themes were identified relating to participants’ differentiation between ceremonial plant medicine use and recreational drug use: (1) participants see a clear delineation between plant medicine use and recreational drug use; (2) plant medicine is seen as a potential treatment for addiction, but concerns exist regarding potential interference with recovery; and (3) plant medicine use may influence recreational use.
Conclusions: More research is needed on who is using plant medicine, motivators for use, perceived and real risks and benefits of plant medicine use and harm reduction techniques regarding safe ingestion.

Ergot Alkaloids and their Hallucinogenic Potential in Morning Glories

Abstract

Naturally occurring and semisynthetic ergot alkaloids play a role in health care or as recreational drugs in Western and indigenous Mexican societies. Evidence is summarized that ergot alkaloids present in Central American Convolvulaceae like Turbina corymbosa, Ipomoea violacea, and Ipomoea asarifolia are colonized by different species of a newly described clavicipitaceous fungal genus named Periglandula. The fungi are associated with peltate glandular trichomes on the adaxial leaf surface of its host plants. The Periglandula fungi are not yet culturable in vitro but were demonstrated to have the capacity to synthesize ergot alkaloids. The alkaloids do not remain in the fungal mycelium but are translocated via the glandular trichomes into their plant host. Both fungi and host benefit from a symbiotic lifestyle. In evolutionary terms the alkaloid biosynthetic gene cluster in the Periglandula/Ipomoea symbiosis is likely to have a conserved (basic) structure while biosynthetic ergot gene clusters within the genera Claviceps and Epichloe were under ecological selection for alkaloid diversification.

Influence of Environmental Factors and Cultural Methods on the Content of N,N‑Dimethyltryptamine in Psychotria viridis (Rubiaceae)

Abstract

Psychotria viridis is one of the species that produces N,N-dimethyltryptamine. Its decoction together with other species, such as Banisteriopsis caapi, produces ayahuasca, a beverage used for ritualistic and medicinal purposes. The goal of this study was to understand how environmental factors and cultivation methods influenced the content of N,N-dimethyltryptamine in P. viridis. Over all four seasons, leaf samples were collected from 25 different locations in 14 Brazilian states, and Federal District. Environmental parameters, micro and macronutrients, plant characteristics, information on farming methods were correlated with N,N-dimethyltryptamine content, determined by gas chromatography coupled to mass spectrometry (GC-MS). Greatest effects on the N,N-dimethyltryptamine amount were associated with seasonality, altitude, latitude and biome type. A positive correlation between N and Mg content and N,N-dimethyltryptamine levels was statistically established. By regression analysis, the adequate foliar nutrient levels that would result in the concentration of N,N-dimethyltryptamine in cultivated plants similar to that of Amazonian P. viridis were equated.
