Long-lasting subjective effects of LSD in normal subjects

Abstract

Rationale

Lysergic acid diethylamide (LSD) and other serotonergic hallucinogens can induce profound alterations of consciousness and mystical-type experiences, with reportedly long-lasting effects on subjective well-being and personality.

Methods

We investigated the lasting effects of a single dose of LSD (200 μg) that was administered in a laboratory setting in 16 healthy participants. The following outcome measures were assessed before and 1 and 12 months after LSD administration: Persisting Effects Questionnaire (PEQ), Mysticism Scale (MS), Death Transcendence Scale (DTS), NEO-Five Factor Inventory (NEO-FFI), and State-Trait Anxiety Inventory (STAI).

Results

On the PEQ, positive attitudes about life and/or self, positive mood changes, altruistic/positive social effects, positive behavioral changes, and well-being/life satisfaction significantly increased at 1 and 12 months and were subjectively attributed by the subjects to the LSD experience. Five-Dimensions of Altered States of Consciousness (5D-ASC) total scores, reflecting acutely induced alterations in consciousness, and Mystical Experience Questionnaire (MEQ30) total scores correlated with changes in well-being/life satisfaction 12 months after LSD administration. No changes in negative attitudes, negative mood, antisocial/negative social effects, or negative behavior were attributed to the LSD experience. After 12 months, 10 of 14 participants rated their LSD experience as among the top 10 most meaningful experiences in their lives. Five participants rated the LSD experience among the five most spiritually meaningful experiences in their lives. On the MS and DTS, ratings of mystical experiences significantly increased 1 and 12 months after LSD administration compared with the pre-LSD screening. No relevant changes in personality measures were found.

Conclusions

In healthy research subjects, the administration of a single dose of LSD (200 μg) in a safe setting was subjectively considered a personally meaningful experience that had long-lasting subjective positive effects.

Psychedelic pleasures: An affective understanding of the joys of tripping

Abstract

BACKGROUND:
This paper considers the pleasures of psychedelic drugs and proposes a Deleuzian understanding of drugged pleasures as affects. In spite of a large body of work on psychedelics, not least on their therapeutic potentials, the literature is almost completely devoid of discussions of the recreational practices and pleasures of entheogenic drugs. Yet, most people do not use psychedelics because of their curative powers, but because they are fun and enjoyable ways to alter the experience of reality.
METHODS:
In the analytical part of the paper, I examine 100 trip reports from an internet forum in order to explore the pleasures of tripping.
RESULTS:
The analyses map out how drugs such as LSD and mushrooms – in combination with contextual factors such as other people, music and nature – give rise to a set of affective modifications of the drug user’s capacities to feel, sense and act.
CONCLUSION:
In conclusion it is argued that taking seriously the large group of recreational users of hallucinogens is important not only because it broadens our understanding of how entheogenic drugs work in different bodies and settings, but also because it may enable a more productive and harm reductive transmission of knowledge between the scientific and recreational psychedelic communities.

Nourishing the Spirit: Exploratory Research on Ayahuasca Experiences along the Continuum of Recovery from Eating Disorders

Eating disorders (EDs) are serious health conditions that are among the most difficult to treat. Innovative treatments are needed and modalities from across cultures must be considered. Ayahuasca is a psychoactive plant-based tea originally used by Amazonian indigenous groups. A growing body of research points to its promise in the healing of various mental health issues. This study explored the potential therapeutic value of ayahuasca in the context of EDs, including the perceived impact of the preparatory diet and the ayahuasca purge. Sixteen individuals previously diagnosed with an ED participated in a semi-structured interview relating to their experiences with ceremonial ayahuasca drinking. Interviews were analyzed using thematic analysis. Themes presented relate to the reduction or cessation of ED and mental health symptoms, shifts in body perception, and the importance of a ceremonial setting and after-care. For some, the preparatory diet resulted in familiar patterns of concern; however, none felt triggered by the purge in ayahuasca. Ceremonial ayahuasca drinking shows promise in the healing of EDs and warrants further research.

Psychoactive substances as a last resort—a qualitative study of self-treatment of migraine and cluster headaches

Abstract

Background

Treatment resistant cluster headache and migraine patients are exploring alternative treatments online. The aim of this study was to improve comprehension regarding the use of non-established or alternative pharmacological treatments used by sufferers of cluster headaches and migraines.

Methods

A qualitative thematic analysis of the users’ own accounts presented in online forum discussions were conducted. The forum boards https://shroomery.org/http://bluelight.org, and https://clusterbusters.org/ met the inclusion criteria and were used for the study.

Results

The analysis resulted in six themes: a desperate need for effective treatmentsthe role of the forum—finding alternative treatments and community supportalternative treatment substancesdosage and regimenseffects and treatment results; and adverse effects. The results provide an insight into why, how, and by which substances and methods sufferers seek relief from cluster headache and migraines.

Conclusions

These patients are in a desperate and vulnerable situation, and illicit psychoactive substances are often considered a last resort. There appeared to be little or no interest in psychoactive effects per se as these were rather tolerated or avoided by using sub-psychoactive doses. Primarily, psilocybin, lysergic acid diethylamide, and related psychedelic tryptamines were reportedly effective for both prophylactic and acute treatment of cluster headache and migraines. Treatment results with cannabis were more unpredictable. No severe adverse events were reported, but it was observed how desperation sometimes spurred risky behavior when obtaining and testing various treatment alternatives. The forum discourse mainly revolved around maximizing treatment results and minimizing potential harms.

Psilocybin-occasioned mystical-type experience in combination with meditation and other spiritual practices produces enduring positive changes in psychological functioning and in trait measures of prosocial attitudes and behaviors

Abstract

Psilocybin can occasion mystical-type experiences with participant-attributed increases in well-being. However, little research has examined enduring changes in traits. This study administered psilocybin to participants who undertook a program of meditation/spiritual practices. Healthy participants were randomized to three groups (25 each): (1) very low-dose (1 mg/70 kg on sessions 1 and 2) with moderate-level (“standard”) support for spiritual-practice (LD-SS); (2) high-dose (20 and 30 mg/70 kg on sessions 1 and 2, respectively) with standard support (HD-SS); and (3) high-dose (20 and 30 mg/70kg on sessions 1 and 2, respectively) with high support for spiritual practice (HD-HS). Psilocybin was administered double-blind and instructions to participants/staff minimized expectancy confounds. Psilocybin was administered 1 and 2 months after spiritual-practice initiation. Outcomes at 6 months included rates of spiritual practice and persisting effects of psilocybin. Compared with low-dose, high-dose psilocybin produced greater acute and persisting effects. At 6 months, compared with LD-SS, both high-dose groups showed large significant positive changes on longitudinal measures of interpersonal closeness, gratitude, life meaning/purpose, forgiveness, death transcendence, daily spiritual experiences, religious faith and coping, and community observer ratings. Determinants of enduring effects were psilocybin-occasioned mystical-type experience and rates of meditation/spiritual practices. Psilocybin can occasion enduring trait-level increases in prosocial attitudes/behaviors and in healthy psychological functioning.

Developing Guidelines and Competencies for the Training of Psychedelic Therapists

Research since the 1950s has shown that psychedelic-assisted psychotherapy has had significant positive effects in reductions of specific clinical symptoms and increases in quality of life as measured on a variety of indices. The intensity of focus on evidence-based outcomes, however, has resulted in a paucity of active discussions and research on the core competencies of the therapists themselves. The context of the history of psychedelic research reveals how this neglect of therapist variables occurred. With current discussions of Phase 3 and expanded access research programs for psilocybin-assisted and MDMA-assisted psychotherapies, there will be a great need for competent therapists trained in this clinical specialty. This is particularly the case if less restricted, legal medical use is approved within the next 6 to 10 years. This article is the first review and compilation of psychedelic therapist competencies derived from the psychedelic literature. These six therapist competencies are empathetic abiding presence; trust enhancement; spiritual intelligence; knowledge of the physical and psychological effects of psychedelics; therapist self-awareness and ethical integrity; and proficiency in complementary techniques. A further contribution of this review is a delineation of the 12 fundamental curricular domains of study for the training and development of these therapist competencies. As current legal restrictions evolve, aspects of these training guidelines will develop accordingly.

Assessing the psychedelic “after-glow” in ayahuasca users: post-acute neurometabolic and functional connectivity changes are associated with enhanced mindfulness capacities

Abstract

BACKGROUND:
Ayahuasca is a plant tea containing the psychedelic 5-HT2A agonist N,N-dimethyltryptamine and harmala monoamine-oxidase inhibitors. Acute administration leads to neurophysiological modifications in brain regions of the default mode network, purportedly through a glutamatergic mechanism. Post-acutely, ayahuasca potentiates mindfulness capacities in volunteers and induces rapid and sustained antidepressant effects in treatment-resistant patients. However, the mechanisms underlying these fast and maintained effects are poorly understood. Here, we investigated in an open-label uncontrolled study in 16 healthy volunteers ayahuasca-induced post-acute neurometabolic and connectivity modifications and their association with mindfulness measures.
METHODS:
Using 1H-magnetic resonance spectroscopy and functional connectivity, we compared baseline and post-acute neurometabolites and seed-to-voxel connectivity in the posterior and anterior cingulate cortex after a single ayahuasca dose.
RESULTS:
Magnetic resonance spectroscopy showed post-acute reductions in glutamate+glutamine, creatine, and N-acetylaspartate+N-acetylaspartylglutamate in the posterior cingulate cortex. Connectivity was increased between the posterior cingulate cortex and the anterior cingulate cortex, and between the anterior cingulate cortex and limbic structures in the right medial temporal lobe. Glutamate+glutamine reductions correlated with increases in the “nonjudging” subscale of the Five Facets Mindfulness Questionnaire. Increased anterior cingulate cortex-medial temporal lobe connectivity correlated with increased scores on the self-compassion questionnaire. Post-acute neural changes predicted sustained elevations in nonjudging 2 months later.
CONCLUSIONS:
These results support the involvement of glutamate neurotransmission in the effects of psychedelics in humans. They further suggest that neurometabolic changes in the posterior cingulate cortex, a key region within the default mode network, and increased connectivity between the anterior cingulate cortex and medial temporal lobe structures involved in emotion and memory potentially underlie the post-acute psychological effects of ayahuasca.
