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.

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.

Ibogaine as a treatment for substance misuse: Potential benefits and practical dangers.

October 12, 2018 / Addiction, Iboga / Ibogaine, Papers, Psychiatry, Psychology, Psychopharmacology, Publications, Safety, Spirituality / By /

Abstract

Ibogaine is an indole alkaloid found in the root bark of the Iboga shrub native to west Africa possessing hallucinogenic properties. For centuries it has been used in religious ceremonies and to gain spiritual enlightenment. However, since the early 1960s, its apparent ability to reduce craving for psychoactive substances including alcohol, cocaine, methamphetamine, opiates, and nicotine has led to its use in detoxification treatments. In many instances, clients receive treatment in non-medical settings, with little by way of robust scientific clinical trials. This chapter provides an overview of the potential benefits that could arise from such research. This is balanced against the serious adverse effects that can occur due to undiagnosed health conditions and/or concomitant use of other drugs. A detailed update is provided of the 33 deaths known to have occurred, including 5 in the UK. Looking forward, there is a need to develop better opiate detoxification treatment against a background of increasing opioid-related fatalities. A congener of ibogaine, 18-MC, appears to be safer and is to undergo clinical trials. In the meantime, would-be consumers and treatment providers must make more careful, detailed risk-assessments before using ibogaine. Treatment outcomes, including deaths, need to be accurately recorded and published.

DARK Classics in Chemical Neuroscience: Ibogaine.

Abstract

The West African iboga plant has been used for centuries by the Bwiti and Mbiri tribes to induce hallucinations during religious ceremonies. Ibogaine, the principal alkaloid responsible for iboga’s psychedelic properties, was isolated and sold as an antidepressant in France for decades before its adverse effects precipitated its removal from the market. An ibogaine resurgence in the 1960s was driven by U.S. heroin addicts who claimed that ibogaine cured their opiate addictions. Behavioral pharmacologic studies in animal models provided evidence that ibogaine could blunt self-administration of not only opiates but cocaine, amphetamines, and nicotine. Ibogaine displays moderate-to-weak affinities for a wide spectrum of receptor and transporter proteins; recent work suggests that its actions at nicotinic acetylcholine receptor subtypes may underlie its reputed antiopiate effects. At micromolar levels, ibogaine is neurotoxic and cardiotoxic and has been linked to several deaths by cardiac arrest. Structure-activity studies led to the isolation of the ibogaine analog 18-methoxycoronaridine (18-MC), an α3β4 nicotinic receptor modulator that retains ibogaine’s anticraving properties with few or no adverse effects. Clinical trials of 18-MC treatment of nicotine addiction are pending. Ibogaine analogs may also hold promise for treating anxiety and depression via the “psychedelic-assisted therapy” approach that employs hallucinogens including psilocybin and methylenedioxymethamphetamine (“ecstasy”).

Awe: a putative mechanism underlying the effects of classic psychedelic-assisted psychotherapy

September 27, 2018 / Mystical experiences, Other subjects, Other substances, Papers, Phenomenology, Psychology, Psychopharmacology, Psychotherapy, Publications, Spirituality / By /

Abstract

A psychological model of classic psychedelic-assisted psychotherapy informed by contemporary scientific data is presented in this paper. It is suggested that classic psychedelic-occasioned mystical experience is characterized by profound awe, a discrete emotion experienced in the presence of a vast stimulus requiring accommodation of mental structures. Awe, in turn, promotes the small self, a construct that, in the extreme, is analogous to those of unitive experience and ego dissolution. The small self is conceptualized as key to understanding the downstream effects of mystical experience occasioned in the context of classic psychedelic-assisted psychotherapy. With this novel theoretical framework in mind, a number of clinical implications and recommendations are provided so as to advance this incipient field of study.

Psychedelics and music: neuroscience and therapeutic implications

September 21, 2018 / Mystical experiences, Other subjects, Other substances, Papers, Psychiatry, Psychology, Psychopharmacology, Psychotherapy, Publications, Spirituality / By / , ,

Abstract

From the beginning of therapeutic research with psychedelics, music listening has been consistently used as a method to guide or support therapeutic experiences during the acute effects of psychedelic drugs. Recent findings point to the potential of music to support meaning-making, emotionality, and mental imagery after the administration of psychedelics, and suggest that music plays an important role in facilitating positive clinical outcomes of psychedelic therapy. This review explores the history of, contemporary research on, and future directions regarding the use of music in psychedelic research and therapy, and argues for more detailed and rigorous investigation of the contribution of music to the treatment of psychiatric disorders within the novel framework of psychedelic therapy.
