Ayahuasca

Assessment of addiction severity among ritual users of ayahuasca

Abstract

Ayahuasca is a psychoactive beverage used for magico-religious purposes in the Amazon. Recently, Brazilian syncretic churches have helped spread the ritual use of ayahuasca abroad. This trend has raised concerns that regular use of this N,N-dimethyltryptamine-containing tea may lead to the medical and psychosocial problems typically associated with drugs of abuse. Here we assess potential drug abuse-related problems in regular ayahuasca users. Addiction severity was assessed using the Addiction Severity Index (ASI), and history of alcohol and illicit drug use was recorded. In Study 1, jungle-based ayahuasca users (n=56) were compared vs. rural controls (n=56). In Study 2, urban-based ayahuasca users (n=71) were compared vs. urban controls (n=59). Follow-up studies were conducted 1 year later. In both studies, ayahuasca users showed significantly lower scores than controls on the ASI Alcohol Use, and Psychiatric Status subscales. The jungle-based ayahuasca users showed a significantly higher frequency of previous illicit drug use but this had ceased at the time of examination, except for cannabis. At follow-up, abstinence from illicit drug use was maintained in both groups except for cannabis in Study 1. However, differences on ASI scores were still significant in the jungle-based group but not in the urban group. Despite continuing ayahuasca use, a time-dependent worsening was only observed in one subscale (Family/Social relationships) in Study 2. Overall, the ritual use of ayahuasca, as assessed with the ASI in currently active users, does not appear to be associated with the deleterious psychosocial effects typically caused by other drugs of abuse.

Opening the Portals of Heaven – Brazilian Ayahuasca Music

This pocket book highlights the theme of music in the ayahuasca religions of Santo Daime (both the Cefluris and Alto Santo groups) and the União do Vegetal (UDV). Although most studies of the ayahuasca religions recognize the centrality of music in their rituals, the study of the music itself has generally been secondary to other themes, rather than the central focus that it is here. A rich cultural manifestation, ayahuasca music reveals multiple connections with Brazilian religiosity and with the musical expression of the Northeast and Amazonia, and has been one of the principal elements highlighted by recent efforts to designate ayahuasca as immaterial cultural heritage of the Brazilian nation. The book explores the key role that music plays in the everyday life of these religions, in the production of religious meanings, and in the construction of the bodies and the subjectivity of adepts. Through a description of each group’s musicality and a comparison among them, the authors seek to understand these groups’ ethos. This book represents an important contribution to an area of study that is still little explored in Brazil: the use of music in ritual and religious contexts.

Dimethyltryptamine (DMT): Subjective effects and patterns of use among Australian recreational users

Abstract

Dimethyltryptamine (DMT) is an endogenous hallucinogen with traditional use as a sacrament in the orally active preparation of ayahuasca. Although the religious use of ayahuasca has been examined extensively, very little is known about the recreational use of DMT. In this study, Australian participants (n = 121) reporting at least one lifetime use of DMT completed an online questionnaire recording patterns of use, subjective effects and attitudes towards their DMT use. Smoking DMT was by far the most common route of administration (98.3%) with a comparatively smaller proportion reporting use of ayahuasca (30.6%). The reasons for first trying DMT were out of a general interest in hallucinogenic drugs (46.6%) or curiosity about DMT’s effects (41.7%), while almost one-third (31.1%) cited possible psychotherapeutic benefits of the drug. An increase in psychospiritual insight was the most commonly reported positive effect of both smoked DMT (75.5%) and ayahuasca (46.7%), a finding that is consistent with other studies examining the ritualised use of ayahuasca in a religious context. Although previous studies of DMT use have examined ayahuasca use exclusively, the present study demonstrates the ubiquity of smoking as the most prevalent route of administration among recreational DMT users.

qNMR: An applicable method for the determination of dimethyltryptamine in ayahuasca, a psychoactive plant preparation

Abstract

Ayahuasca is an Amazonian plant beverage obtained by infusing the pounded stems of Banisteriopsis caapi in combination with the leaves of Psychotria viridis. P. viridis contains the psychedelic indole N,N-dimethyltryptamine (DMT). This association has a wide range of use in religious rituals around the world. In the present work, an easy, fast and non-destructive method by Nuclear Magnetic Resonance of proton (1H NMR) for quantification of DMT in ayahuasca samples was developed and validated. 2,5-Dimethoxybenzaldehyde (DMBO) was used as internal standard (IS). For this purpose, the area ratios produced by protons of DMT (N(CH3)2) at 2.70 ppm, singlet, (6H) and for DMBO (Ar(OCH3)2) at 3.80 and 3.89 ppm, doublet, (6H) were used for quantification. The lower limit of quantification (LLOQ) was 12.5 μg/mL and a good intra-assay precision was also obtained (relative standard deviation < 5.1%). The present 1H NMR method is not time consuming and can be readily applied to monitor this tryptamine in plant preparations. We believe that qNMR can be used for identification and quantification of many plant-based products and metabolites with important advantages, while comparing with other analytical techniques.

Composition, Standardization and Chemical Profiling of Banisteriopsis caapi, a Plant for the Treatment of Neurodegenerative Disorders Relevant to Parkinson’s Disease

Abstract

Ethnopharmacological relevance

Banisteriopsis caapi, a woody vine from the Amazonian basin, is popularly known as an ingredient of a sacred drink ayahuasca, widely used throughout the Amazon as a medicinal tea for healing and spiritual exploration. The usefulness of Banisteriopsis caapi has been established for alleviating symptoms of neurological disorders including Parkinson’s disease.

Aim of the study

Primary objective of this study was to develop the process for preparing standardized extracts of Banisteriopsis caapi to achieve high potency for inhibition of human monoamine oxidases (MAO) and antioxidant properties. The aqueous extracts prepared from different parts of the plant collected from different geographical locations and seasons were analyzed by HPLC for principal bioactive markers. The extracts were simultaneously tested in vitro for inhibition of human MAOs and antioxidant activity for analysis of correlation between phytochemical composition of the extracts and bioactivities.

Materials and methods

Reversed-phase HPLC with photodiode array detection was employed to profile the alkaloidal and non-alkaloidal components of the aqueous extract of Banisteriopsis caapi. The Banisteriopsis caapi extracts and standardized compositions were tested in vitro for inhibition of recombinant preparations of human MAO-A and MAO-B. In vitro cell-based assays were employed for evaluation of antioxidant property and mammalian cell cytotoxicity of these preparations.

Results

Among the different aerial parts, leaves, stems/large branches and stem bark of Banisteriopsis caapi, HPLC analysis revealed that most of the dominant chemical and bioactive markers (1, 2, 5, 7–9) were present in high concentrations in dried bark of large branch. A library of HPLC chromatograms has also been generated as a tool for fingerprinting and authentication of the studied Banisteriopsis caapi species. The correlation between potency of MAO inhibition and antioxidant activity with the content of the main active constituents of the aqueous Banisteriopsis caapi extracts and standardized compositions was established. Phytochemical analysis of regular/commercial Banisteriopsis caapi dried stems, obtained from different sources, showed a similar qualitative HPLC profile, but relatively low content of dominant markers 1, 2, 7, and 9, which led to decreased MAO inhibitory and antioxidant potency compared to Banisteriopsis caapi Da Vine.

Conclusion

The ethnopharmacological use of bark of matured stem/large branch of Banisteriopsis caapi as well as whole matured stem is supported by the results obtained in this investigation. Among various constituents of Banisteriopsis caapi, harmine (7), harmaline (6) and tetrahydroharmine (5) are responsible for MAO-A inhibition, while two major proanthocyanidines, epicatechin (8) and procyanidine B2 (9) produce antioxidant effects. The compounds 1–9 can serve as reliable markers for identification and standardization of Banisteriopsis caapi aerial parts, collected in different seasons and/or from different geographical regions.

Ayahuasca Beyond the Amazon: the Benefits and Risks of a Spreading Tradition

Abstract

Ayahuasca, a hallucinogenic plant brew from the Amazon basin used as part of healing ceremonies by the region’s indigenous people for centuries, is now consumed by growing numbers of people throughout the world. Ayahuasca consumption has moved from strictly being part of indigenous shamanic healing ceremonies, to being a key component of the Brazilian syncretic churches formed in the last century, to most recently being part of ‘‘New Age’’ rituals conducted throughout the Western world. The discovery of ayahuasca by the Westerners, has resulted in a growing body of research suggesting that participants who take part in ayahuasca ceremonies experience significant spiritual and psychotherapeutic effects. Along with these potential benefits, however, the adoption of indigenous practices into Western cultures brings simultaneous challenges. As participation in ayahuasca ritual spreads into Western cultures, it becomes necessary to examine how to integrate these spiritual healing rituals into contemporary Western concepts of psychological health and ethical conduct.

The persistence of the subjective in neuropsychopharmacology: observations of contemporary hallucinogen research

Abstract

The elimination of subjectivity through brain research and the replacement of so-called ‘folk psychology’ by a neuroscientifically enlightened worldview and self-conception has been both hoped for and feared. But this cultural revolution is still pending. Based on nine months of fieldwork on the revival of hallucinogen research since the ‘Decade of the Brain,’ this paper examines how subjective experience appears as epistemic object and practical problem in a psychopharmacological laboratory. In the quest for neural correlates of (drug-induced altered states of) consciousness, introspective accounts of test subjects play a crucial role in neuroimaging studies. Firsthand knowledge of the drugs’ flamboyant effects provides researchers with a personal knowledge not communicated in scientific publications, but key to the conduct of their experiments. In many cases, the ‘psychedelic experience’ draws scientists into the field and continues to inspire their self-image and way of life. By exploring these domains the paper points to a persistence of the subjective in contemporary neuropsychopharmacology.

Experiences of Encounters with Ayahuasca – “the Vine of the Soul”

Abstract

Ayahuasca is a psychoactive brew used by the indigenous populations of the Amazon. The aim of this qualitative study was to gain insight into the experiences of western users of ayahuasca, as well as to ascertain the experienced meaning that participants felt by their participation. Twenty-five people from Northern Europe with experiences of group sessions with ayahuasca wrote anonymous descriptions of their experiences. The Empirical Phenomenological Psychological method was used for this analysis. The analysis resulted in 33 c^egories which weie assembled into six getieral themes: (a) motivation and aim, (h) contractile frightening state (c) sudden transformation of the experience, (d) limitless expansive states with transcendental experiences, (f) reflections, and (g) changed woridview and new orientation to life. These themes provided a new structure, called the transcendental circle. Participants reponed many positive psychological and physical improvements that indicate that ayahuasca could be of potential interest in the development of new medicines and therapies.

Ayahuasca–From Dangerous Drug to National Heritage: An Interview with Antonio A. Arantes

Abstract

This interview with Antonio A. Arantes, Brazilian anthropology professor and recognized specialist on the topics of intellectual property and traditional knowledge, addresses the 2008 request by Brazilian ayahuasca groups to be recognized as part of the immaterial cultural heritage of Brazil. In the first portion of the interview, Arantes reflects on the challenges of the new conceptions of the Brazilian national immaterial policy program. He discusses several examples of cultural goods recognized by the Brazilian state, such as the candomblé and the samba, and analyzes the controversial issues involving authenticity and tradition in these and other similar cases. In the second portion, Arantes reflects on the specific case of ayahuasca, the relationship of this cultural heritage request to legal issues, the challenges to define exactly what aspects should be recognized, and speculates on the chances that these religious groups will come to be recognized as a national symbol of Brazil.
