Abstract

Naturally occurring and psychedelic drug-occasioned experiences interpreted as personal encounters with God are well described but have not been systematically compared. In this study, five groups of individuals participated in an online survey with detailed questions characterizing the subjective phenomena, interpretation, and persisting changes attributed to their single most memorable God encounter experience (n = 809 Non-Drug, 1184 psilocybin, 1251 lysergic acid diethylamide (LSD), 435 ayahuasca, and 606 N,N-dimethyltryptamine (DMT)). Analyses of differences in experiences were adjusted statistically for demographic differences between groups. The Non-Drug Group was most likely to choose “God” as the best descriptor of that which was encountered while the psychedelic groups were most likely to choose “Ultimate Reality.” Although there were some other differences between non-drug and the combined psychedelic group, as well as between the four psychedelic groups, the similarities among these groups were most striking. Most participants reported vivid memories of the encounter experience, which frequently involved communication with something having the attributes of being conscious, benevolent, intelligent, sacred, eternal, and all-knowing. The encounter experience fulfilled a priori criteria for being a complete mystical experience in approximately half of the participants. More than two-thirds of those who identified as atheist before the experience no longer identified as atheist afterwards. These experiences were rated as among the most personally meaningful and spiritually significant lifetime experiences, with moderate to strong persisting positive changes in life satisfaction, purpose, and meaning attributed to these experiences. Among the four groups of psychedelic users, the psilocybin and LSD groups were most similar and the ayahuasca group tended to have the highest rates of endorsing positive features and enduring consequences of the experience. Future exploration of predisposing factors and phenomenological and neural correlates of such experiences may provide new insights into religious and spiritual beliefs that have been integral to shaping human culture since time immemorial.

Abstract

The fields of palliative and holistic nursing both maintain a commitment to the care of the whole person, including a focus on spiritual care. Advanced serious illness may pose a plethora of challenges to patients seeking to create meaning and purpose in their lives. The purpose of this article is to introduce scholarly dialogue on the integration of entheogens, medicines that engender an experience of the sacred, into the spiritual and holistic care of patients experiencing advanced serious illness. A brief history of the global use of entheogens as well as a case study are provided. Clinical trials show impressive preliminary findings regarding the healing potential of these medicinal agents. While other professions, such as psychology, pharmacy, and medicine, are disseminating data related to patient outcomes secondary to entheogen administration, the nursing literature has not been involved in raising awareness of such advancements. Research is illustrating their effectiveness in achieving integrative experiences for patients confronting advanced serious illness and their ability to promote presence, introspection, decreased fear, and increased joy and acceptance. Evidence-based knowledge surrounding this potentially sensitive topic is necessary to invite understanding, promote scientific knowledge development, and create healing environments for patients, nurses, and researchers alike.

Ibogaine and Subjective Experience: Transformative States and Psychopharmacotherapy in the Treatment of Opioid Use Disorder

April 9, 2019 / Addiction, Consciousness, Iboga / Ibogaine, Mystical experiences, Papers, Phenomenology, Psychiatry, Psychology, Psychopharmacology, Publications, Spirituality / By / , ,

Abstract

This article examines the therapeutic potential of ibogaine, a powerful oneiric alkaloid derived from Tabernanthe iboga, through exploring the subjective experiences of 44 participants from two observational treatment studies for opioid use disorder. Following treatment with ibogaine HCl, the participants (Mexico, n = 30; New Zealand, n = 14) completed the States of Consciousness Questionnaire (SCQ) to quantify the magnitude of their psychotropic experience. Participants were asked to provide written transcripts of their experiences, with those supplied being analyzed thematically through an iterative process, to produce a set of coded themes. Mean SCQ scores in many domains exceeded 0.6, the cutoff score for a “complete mystical experience,” with 43% of participants achieving this in more than five of seven domains. Qualitative data described multiple phenomenological themes, including auditory and visual phenomena. Ibogaine’s strong oneiric action promoted cyclic visions leading to confronting realizations involving remorse and regret for participants’ actions towards others, but also release from feelings of guilt and worthlessness. Many participants reported feeling a sense of spiritual transformation. We propose that the reported experiences support the meaningfulness of ibogaine’s oneiric effects as a discrete element in its capacity for healing, which is distinct from pharmacological actions associated with reduced withdrawal and craving.

Neurochemical models of near-death experiences: A large-scalestudy based on the semantic similarity of written reports

Abstract

The real or perceived proximity to death often results in a non-ordinary state of consciousness characterized by phenomenological features such as the perception of leaving the body boundaries, feelings of peace, bliss and timelessness, life review, the sensation of traveling through a tunnel and an irreversible threshold. Near-death experiences (NDEs) are comparable among individuals of different cultures, suggesting an underlying neurobiological mechanism. Anecdotal accounts of the similarity between NDEs and certain drug-induced altered states of consciousness prompted us to perform a large-scale comparative analysis of these experiences. After assessing the semantic similarity between ≈15,000 reports linked to the use of 165 psychoactive substances and 625 NDE narratives, we determined that the N-methyl-D-aspartate (NMDA) receptor antagonist ketamine consistently resulted in reports most similar to those associated with NDEs. Ketamine was followed by Salvia divinorum (a plant containing a potent and selective κ receptor agonist) and a series of serotonergic psychedelics, including the endogenous serotonin 2A receptor agonist N,N-Dimethyltryptamine (DMT). This similarity was driven by semantic concepts related to consciousness of the self and the environment, but also by those associated with the therapeutic, ceremonial and religious aspects of drug use. Our analysis sheds light on the long-standing link between certain drugs and the experience of “dying“, suggests that ketamine could be used as a safe and reversible experimental model for NDE phenomenology, and supports the speculation that endogenous NMDA antagonists with neuroprotective properties may be released in the proximity of death.

Transformative Psychopharmacology: the Case of 5-Methoxy-N,N-Dimethyltryptamine

January 2, 2019 / DMT, Indigenous use, Mystical experiences, Neuroscience, Other substances, Papers, Psychopharmacology, Publications, Toxicology / By /

Abstract

Since the 2nd part of last century neo-shamanic rituals using mind-altering extracts from plants or animals have become increasingly popular in Europe and the USA. The first rituals coming to the west were based on drinking a special Amazonian tea, Ayahuasca, based on 2 different plants, with active compounds belonging to the class of the beta-carbolines (harmala alkaloids) and tryptamines. The use of such compounds will be described from the perspective of the transformative psychopharmacology: that part of psychopharmacology studying the use of psychoactive compounds to achieve a new balance, a transformation or healing and sometimes even leading to a cure. Examples of curing are meanwhile well documented, for instance the positive influence on drug abuse and addiction, alcoholism. The importance of the healing aspects of these rituals however are often neglected or overlooked. For users, these are key however. As medicine becomes more and more personalized and postmodern, it will be relevant to understand why patients and healthy people decide to participate in healing rituals based on psycho-active compounds. We will present the pharmacology, the transformative psychopharmacology, the effects and adverse events of 5-methoxy-N, N-dimethyltryptamine (5-MeO-DMT) and its place in postmodern medicine.

A Jamesian Response to Reductionism in the Neuropsychology of Religious Experience

December 13, 2018 / Mystical experiences, Other substances, Papers, Philosophy, Publications, Religious studies, Sociology, Spirituality / By / ,

Abstract

The neuroscience revolution has revived interpretations of religious experiences as wholly dependent on biological conditions. William James cautioned against allowing such neurological reductionism to overwhelm other useful perspectives. Contemporary psychologists of religion have raised similar cautions, but have failed to engage James as a full conversation partner. In this article, we present a contemporary, applied version of James’s perspective. We clarify the problem by reviewing specific James-like contemporary concerns about reductionism in the neuropsychological study of religion. Then, most centrally, we employ three of James’s conceptual tools—pragmatism, pluralism, and radical empiricism—to moderate contemporary reductionism. Finally, we point to a constructive approach through which neuroscientists might collaborate with scholars in the humanities and psychosocial sciences, which is consistent with our conclusion that it is often no longer fruitful to separate neurobiological studies from studies that are psychosocial or sociocultural.

Intensity of Mystical Experiences Occasioned by 5-MeO-DMT and Comparison With a Prior Psilocybin Study

December 6, 2018 / DMT, Mystical experiences, Papers, Psychology, Psychopharmacology, Publications / By / , , , , , ,

Abstract

5-MeO-DMT is a psychoactive substance found in high concentrations in the bufotoxin of the Colorado River Toad (Bufo alvarius). Emerging evidence suggests that vaporized 5-MeO-DMT may occasion mystical experiences of comparable intensity to those occasioned by more widely studied psychedelics such as psilocybin, but no empirical study has tested this hypothesis. Data was obtained from 20 individuals (Mage = 38.9, ± 10.7; male = 55%, Caucasian = 85%) who were administered 5-MeO-DMT as part of a psychospiritual retreat program in Mexico. All participants received 50 mg of inhaled vaporized toad bufotoxin which contains 5-MeO-DMT and completed the Mystical Experience Questionnaire (MEQ30) approximately 4–6 h after their session. Administration of 5-MeO-DMT occasioned strong mystical experiences (MEQ30 Overall Mintensity = 4.17, ± 0.64, range 0–5) and the majority (n = 15, 75%) had “a complete mystical experience” (≥60% on all MEQ30 subscales). Compared to a prior laboratory-based psilocybin study, there were no differences in the intensity of mystical effects between 5-MeO-DMT and a high dose (30 mg/70 kg) of psilocybin, but the intensity of mystical effects was significantly higher in the 5-MeO-DMT sample compared to moderate/high dose (20 mg/70 kg) of psilocybin (MEQ30 Total Score: p = 0.02, d = 0.81). Administration of vaporized 5-MeO-DMT reliably occasioned complete mystical experiences in 75% of individuals and was similar in intensity to high dose psilocybin administered in a laboratory setting. The short duration of action may be advantageous for clinical interventions and for studying mystical-type experiences.

Classic Psychedelics: An integrative review of epidemiology, mystical experience, brain network function, and therapeutics

Abstract

The purpose of this paper is to provide an integrative review and offer novel insights regarding human research with classic psychedelics (classic hallucinogens), which are 5HT2AR agonists such as lysergic acid diethylamide (LSD), mescaline, and psilocybin. Classic psychedelics have been administered as sacraments since ancient times. They were of prominent interest within psychiatry and neuroscience in the 1950s to 1960s, and during this time contributed to the emergence of the field of molecular neuroscience. Promising results were reported for treatment of both end-of-life psychological distress and addiction, and classic psychedelics served as tools for studying the neurobiological bases of psychological disorders. Moreover, classic psychedelics were shown to occasion mystical experiences, which are subjective experiences reported throughout different cultures and religions involving a strong sense of unity, among other characteristics. However, the recreational use of classic psychedelics and their association with the counterculture prompted an end to human research with classic psychedelics in the early 1970s. We review recent therapeutic studies suggesting efficacy in treating psychological distress associated with life-threatening diseases, treating depression, and treating nicotine and alcohol addictions. We also describe the construct of mystical experience, and provide a comprehensive review of modern studies investigating classic psychedelic-occasioned mystical experiences and their consequences. These studies have shown classic psychedelics to fairly reliably occasion mystical experiences. Moreover, classic psychedelic-occasioned mystical experiences are associated with improved psychological outcomes in both healthy volunteer and patient populations. We also review neuroimaging studies that suggest neurobiological mechanisms of psychedelics. These studies have also broadened our understanding of the brain, the serotonin system, and the neurobiological basis of consciousness. Finally, we provide the most comprehensive review of epidemiological studies of classic psychedelics to date. Notable among these are a number of studies which have suggested the possibility that nonmedical naturalistic (non-laboratory) use of classic psychedelics is associated with positive mental health and prosocial outcomes, although it is clear that some individuals are harmed by classic psychedelics in non-supervised settings. Overall, these various lines of research suggest that classic psychedelics might hold strong potential as therapeutics, and as tools for experimentally investigating mystical experiences and behavioral-brain function more generally.

An exploratory study of experiences with conventional eating disorder treatment and ceremonial ayahuasca for the healing of eating disorders

November 24, 2018 / Anxiety disorders / PTSD, Ayahuasca, Mystical experiences, Papers, Psychiatry, Psychology, Psychopharmacology, Psychotherapy, Publications, Religious studies / By / , , , , ,

Abstract

Purpose

Ayahuasca is a traditional Amazonian medicine that is currently being researched for its potential in treating a variety of mental disorders. This article reports on exploratory qualitative research relating to participant experiences with ceremonial ayahuasca drinking and conventional treatment for eating disorders (EDs). It also explores the potential for ayahuasca as an adjunctive ED treatment.

Methods

Thirteen individuals previously diagnosed with an ED participated in a semi-structured interview contrasting their experiences with conventional ED treatment with experiences from ceremonial ayahuasca. The interviews were analyzed using thematic analysis.

Results

Participant reports were organized with key themes including that ayahuasca: led to rapid reductions in ED thoughts and symptoms; allowed for the healing of the perceived root of the ED; helped to process painful feelings and memories; supported the internalization of greater self-love and self-acceptance; and catalyzed spiritual elements of healing.

Conclusions

The results suggest that ayahuasca may have potential as a valuable therapeutic tool, and further research—including carefully controlled clinical trials—is warranted.
