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

/ Ayahuasca, Biology & Ethnobotany, Humanities & Art, Papers, Publications, Scientific Discipline / /

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.

Placebo Problems: Boundary Work in the Psychedelic Science Renaissance

/ LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications / /

Abstract

The revitalization of clinical trials with psychedelics has produced an array of studies investigating different combinations of therapeutic substances and diagnoses. In addition to the bureaucratic negotiations to gain approval for this research, this new wave of studies is also negotiating a new methodological landscape of clinical research. Mid-twentieth century research with drugs like LSD and psilocybin involved both case studies and double-blind studies. However, today, placebo-controlled randomized controlled trials (RCTs) are the institutional standard for research with psychopharmaceuticals. Because psychedelic therapy seeks to induce a radical change in consciousness—to make a subject feel different from her everyday self—blinding these studies using placebo controls has emerged as a methodological sticking point. However, this chapter argues, it is also a rich site for interrogating boundary work around science and psychedelics. While anthropologists have examined placebos as examples of the power of symbolic healing within Western medicine, or as ethically fraught territory of nontreatment, this chapter examines placebos as a research technique around which the scientific status of a study is negotiated. While psychedelic therapy challenges the model of pharmaceutical intervention used in psychiatry today, it must do so while also working within psychopharmacology’s evidentiary norms.

Bubbling with Controversy: Legal Challenges for Ceremonial Ayahuasca Circles in the United States

/ Ayahuasca, Papers, Publications, Scientific Discipline / / , ,

Abstract

The use of ayahuasca has been spreading rapidly worldwide; however, no current statistics are available to provide a comprehensive understanding of the scope or pace of this expansion. In the United States, the expansion has included the appearance of the Brazilian ayahuasca religions Santo Daime and União do Vegetal (UDV), underground ceremonial circles, workshops with itinerant Amazonian shamans, and spiritual retreat centers. This trend has included the recent emergence of groups and organizations that publicly advertise “legal” ayahuasca ceremonies and retreats. This chapter maps the existence of a series of organizations and actors who have controversially claimed legal protection through incorporation as “branches” of the Native American Church (NAC). The legality, religious character, and sincerity of these churches are reviewed in light of governing law, such as the First Amendment of the US Constitution, the Religious Freedom Restoration Act (RFRA), the Controlled Substances Act (CSA), and pertinent court cases involving the UDV and the Santo Daime, as well as ethnographic accounts of the historical Native American Church. Finally, it examines a petition for a religious exemption from the CSA from Ayahuasca Healings and speculates on the possibilities of the future of ayahuasca legality in the United States.

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

/ Anthropology & Sociology, Biology & Ethnobotany, Mushrooms / Psilocybin, Papers, Publications / /

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.

Who Is Keeping Tabs? LSD Lessons from the Past for the Future

/ Ayahuasca, Humanities & Art, LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications / /

Abstract

Psychedelics fell from medical grace nearly half a century ago, but recent activity suggests that some researchers are optimistic about their return. Are they at risk, however, of facing the same historic challenges with a new generation of psychedelic enthusiasts, or have the circumstances changed sufficiently to allow for a new path forward? The twenty-first-century incarnation of psychedelic research resurrects some anticipated hypotheses and explores some of the same applications that clinicians experimented with 50 years ago. On the surface then, the psychedelic renaissance might be dismissed for retreading familiar ground. A deeper look at the context that gave rise to these questions, though, suggests that while some of the questions are common, the culture of neuroscience and the business of drug regulation have changed sufficiently to warrant a retrial. A close look at the history of psychedelics encourages us to think carefully about the roles of regulators, the enthusiasm of researchers, and our cultural fascination and/or repulsion with mind-altering molecules.

Peyote’s Race Problem

/ Anthropology & Sociology, Mescaline / Cacti, Papers, Publications / /

Abstract

In the years since peyote became a controlled substance in Mexico and the US, a steady stream of advocates and activists have laid claim to two types of exemption, rooted in both US Law (the First Amendment) and International Law (the 1971 Vienna Convention on Psychotropic Drugs). Indigenous peyotists in particular have been largely successful in making a claim to a legal right to be exempt from national prohibitions on peyote possession and consumption. This has represented a significant advance in indigenous rights, yet in both contexts it has had the unpleasant effect of signaling that a drug that is otherwise so dangerous as to be prohibited should be permitted for Indians, because they are somehow essentially different from all other citizens. This, then, is Peyote’s Race Problem. The ways in which we have created a legal framework that makes peyote use licit among indigenous peoples has hardened a certain notion of profound, an unalterable difference to the point that Indian bodies are said to be incommensurably different from the bodies of others who might desire to consume peyote, but for whom it is deemed too dangerous. This notion of difference has been exacerbated by the increasing scarcity of peyote in the US and Mexico, which as further racialized the spaces where peyote grows.

The Use of Salvia divinorum from a Mazatec Perspective

/ Anthropology & Sociology, Salvia / Salvinorin A, Scientific Discipline, Substance / /

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.

Ibogaine Acute Administration in Rats Promotes Wakefulness, Long-Lasting REM Sleep Suppression, and a Distinctive Motor Profile

/ Iboga / Ibogaine, Neuroscience, Papers, Publications / / , , , , , ,

Abstract

Ibogaine is a potent psychedelic alkaloid that has been the focus of intense research because of its intriguing anti-addictive properties. According to anecdotic reports, ibogaine has been originally classified as an oneirogenic psychedelic; i.e., induces a dream-like cognitive activity while awake. However, the effects of ibogaine administration on wakefulness (W) and sleep have not been thoroughly assessed. The main aim of our study was to characterize the acute effects of ibogaine administration on W and sleep. For this purpose, polysomnographic recordings on chronically prepared rats were performed in the light phase during 6 h. Animals were treated with ibogaine (20 and 40 mg/kg) or vehicle, immediately before the beginning of the recordings. Furthermore, in order to evaluate associated motor behaviors during the W period, a different group of animals was tested for 2 h after ibogaine treatment on an open field with video-tracking software. Compared to control, animals treated with ibogaine showed an increase in time spent in W. This effect was accompanied by a decrease in slow wave sleep (SWS) and rapid-eye movements (REM) sleep time. REM sleep latency was significantly increased in animals treated with the higher ibogaine dose. While the effects on W and SWS were observed during the first 2 h of recordings, the decrement in REM sleep time was observed throughout the recording time. Accordingly, ibogaine treatment with the lower dose promoted an increase on locomotion, while tremor and flat body posture were observed only with the higher dose in a time-dependent manner. In contrast, head shake response, a behavior which has been associated in rats with the 5HT2A receptor activation by hallucinogens, was not modified. We conclude that ibogaine promotes a waking state that is accompanied by a robust and long-lasting REM sleep suppression. In addition, it produces a dose-dependent unusual motor profile along with other serotonin-related behaviors. Since ibogaine is metabolized to produce noribogaine, further experiments are needed to elucidate if the metabolite and/or the parent drug produced these effects.

Ketamine Effects on EEG during Therapy of Treatment-Resistant Generalized Anxiety and Social Anxiety

/ Depressive Disorders, Ketamine, Neuroscience, Papers, Psychology, Publications / / , , , , ,

Abstract

BACKGROUND:
Ketamine is swiftly effective in a range of neurotic disorders that are resistant to conventional antidepressant and anxiolytic drugs. The neural basis for its therapeutic action is unknown. Here we report the effects of ketamine on the EEG of patients with treatment-resistant generalized anxiety and social anxiety disorders.
METHODS:
Twelve patients with refractory DSM-IV generalized anxiety disorder and/or social anxiety disorder provided EEG during 10 minutes of relaxation before and 2 hours after receiving double-blind drug administration. Three ascending ketamine dose levels (0.25, 0.5, and 1 mg/kg) and midazolam (0.01 mg/kg) were given at 1-week intervals to each patient, with the midazolam counterbalanced in dosing position across patients. Anxiety was assessed pre- and postdose with the Fear Questionnaire and HAM-A.
RESULTS:
Ketamine dose-dependently improved Fear Questionnaire but not HAM-A scores, decreased EEG power most at low (delta) frequency, and increased it most at high (gamma) frequency. Only the decrease in medium-low (theta) frequency at right frontal sites predicted the effect of ketamine on the Fear Questionnaire. Ketamine produced no improvement in Higuchi’s fractal dimension at any dose or systematic changes in frontal alpha asymmetry.
CONCLUSIONS:
Ketamine may achieve its effects on treatment-resistant generalized anxiety disorder and social anxiety disorder through related mechanisms to the common reduction by conventional anxiolytic drugs in right frontal theta. However, in the current study midazolam did not have such an effect, and it remains to be determined whether, unlike conventional anxiolytics, ketamine changes right frontal theta when it is effective in treatment-resistant depression.

Effects of N, N-Dimethyltryptamine on Rat Behaviors Relevant to Anxiety and Depression

/ Anxiety Disorders / PTSD, Ayahuasca, Depressive Disorders, DMT, Papers, Psychology, Publications / / , , ,

Abstract

Depression and anxiety disorders are debilitating diseases resulting in substantial economic costs to society. Traditional antidepressants often take weeks to months to positively affect mood and are ineffective for about 30% of the population. Alternatives, such as ketamine, a dissociative anesthetic capable of producing hallucinations, and the psychoactive tisane ayahuasca, have shown great promise due to their fast-acting nature and effectiveness in treatment-resistant populations. Here, we investigate the effects of N, N-dimethyltryptamine (DMT), the principle hallucinogenic component of ayahuasca, in rodent behavioral assays relevant to anxiety and depression using adult, male, Sprague-Dawley rats. We find that while DMT elicits initial anxiogenic responses in several of these paradigms, its long-lasting effects tend to reduce anxiety by facilitating the extinction of cued fear memory. Furthermore, DMT reduces immobility in the forced swim test, which is a characteristic behavioral response induced by many antidepressants. Our results demonstrate that DMT produces antidepressant and anxiolytic behavioral effects in rodents, warranting further investigation of ayahuasca and classical psychedelics as treatments for depression and post-traumatic stress disorder.
