Dissolving the self

Philosophy and the Mind Sciences  – March 24, 2020

Summary

Psychedelic drugs like psilocybin profoundly alter consciousness, often dissolving the self – a phenomenon of deep philosophical and psychological interest. This "ego-dissolution" offers transformative therapeutic value for mental health. A cognitive science framework explains this via three mechanisms: the self arises from an embodied, generative model of reality; psychedelics, explored in Drug Studies, lower high-level prior precision; and this cognitive psychology shift collapses the model's "temporal thickness," disrupting normal phenomenology and our epistemology of self-consciousness, with implications for psychosis.

Abstract

Psychedelic drugs such as psilocybin, LSD and DMT are known to induce powerful alterations in phenomenology. Perhaps of most philosophical and scie...

Distinct acute effects of LSD, MDMA, and d-amphetamine in healthy subjects

Neuropsychopharmacology  – November 16, 2019

Summary

Lysergic acid diethylamide (LSD) induces profoundly distinct psychological effects compared to MDMA (Ecstasy) or Dextroamphetamine. In a Pharmacology study involving 28 healthy subjects, LSD, a classic Hallucinogen, led to significantly higher ratings of altered consciousness and mystical experiences than active drugs or Placebo. While all three substances—including the Stimulant Amphetamine—showed similar autonomic responses, MDMA uniquely increased oxytocin, reflecting Neurotransmitter Receptor Influence on Behavior. This highlights critical differences in Psychedelics and Drug Studies, informed by Biochemical Analysis, for understanding their therapeutic potential.

Expectancies for Subjective and Antidepressant Effects in Psilocybin Users

Journal of Humanistic Psychology  – September 22, 2023

Summary

Over 500 individuals using psilocybin, a potent hallucinogen, hold specific expectations about its antidepressant effects, crucial for clinical psychology. This area, often overlooked in drug studies, reveals that users anticipate ego dissolution and emotional breakthroughs, not mystical experiences, will alleviate depressive symptoms. Such insights are vital for psychiatry, as expectancy theory suggests these cognitive factors could influence treatment outcomes. Psilocybin's action, a naturally occurring alkaloid, impacts cognition and could be monitored in future antidepressant trials, linking to neurotransmitter receptor influence on behavior. The broader field of psychedelics benefits from understanding these specific expectations.

Abstract

Cannabis-induced oceanic boundlessness

Journal of Psychopharmacology  – March 28, 2021

Summary

High doses of Cannabis can induce subjective "breakthrough" experiences mirroring those from the Hallucinogen Psilocybin. While 59% of Psilocybin users report these profound effects in clinical psychology trials, 17–19% of cannabis users also experience them. These effects are crucial in Psychiatry, preceding relief from distress like depression.

Remarkably, relaxation during psychedelic-assisted therapy, not mystical experiences, best predicted significant antidepressant effects. Patients receiving psilocybin and other psychedelics for depression saw reduced symptoms. Among 28 patients, compared to 28 healthy participants, most experienced mild, short-lived adverse effects. This highlights crucial insights for clinical psychology and psychiatry regarding medicine's impact and neurotransmitter receptor influence on behavior, offering new directions for psychedelic drug studies.

On the varieties of conscious experiences: Altered Beliefs Under Psychedelics (ALBUS).

Neuroscience of consciousness  – January 01, 2025

Summary

Psychedelics can both weaken and strengthen belief systems in the brain, similar to lucid dreaming states. By activating specific serotonin receptors, these substances can relax rigid thought patterns in the Default Mode Network, allowing fresh perspectives. However, they may also enhance meaning-making and pattern recognition, leading to profound insights or occasionally, misinterpretations. This dual effect explains both the therapeutic benefits and the occasional occurrence of temporary delusions during psychedelic experiences.

Values and Beliefs of Psychedelic Drug Users: A Cross-Cultural Study

Journal of Psychoactive Drugs  – June 01, 2006

Summary

Individuals who use hallucinogens like psilocybin demonstrate a distinct psychological profile, scoring higher on mystical beliefs, spirituality, and concern for others, while valuing financial prosperity less. This pattern emerged from a psychology study of 183 people, including 88 psychedelic users, 29 non-psychedelic illegal drug users, and 66 social drinkers, and held true across cultures. Furthermore, both groups using illegal drugs exhibited greater empathy than social drinkers. This suggests unique enduring psychological characteristics, though pre-existing traits of users may contribute to these associations with psychedelics.

Multidimensional Ego-Dissolution Assessment (MEDA): Scale Development and Substance-Specific Comparisons

OpenAlex  – March 02, 2026

Summary

Ego-dissolution, a therapeutic mechanism in psychedelic-assisted therapy, was effectively captured using the Multidimensional Ego-Dissolution Assessment (MEDA) with 207 participants. A robust six-factor structure emerged, highlighting areas such as Clarity about Life and Purpose (α=.78) and Pleasure (α=.78). Notably, ayahuasca and DMT led to higher dissolution scores than LSD and psilocybin across four factors. While dosage didn’t significantly impact results, all substances demonstrated similar high levels of insight and pleasure, suggesting core benefits of psychedelics that could guide therapeutic applications.

Abstract

Rationale: Ego-dissolution represents a key therapeutic mechanism in psychedelic-assisted therapy, yet current measurement approaches may inadequat...

Safety, tolerability and subjective effects of vaporized N,N-Dimethyltryptamine: A randomized double-blind clinical trial.

European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology  – June 17, 2025

Summary

Vaporized N,N-Dimethyltryptamine (DMT) offers a uniquely brief, intense psychedelic experience, prompting interest in its clinical potential. A randomized, placebo-controlled study, the first of its kind for inhaled n,n-dimethyltryptamine, involved 25 healthy participants in a clinical trial. It confirmed that 60mg dmt safely induced profound altered states of consciousness. Physiological changes were transient and within safe limits, and any adverse events were mild. This well-tolerated compound shows significant promise for future therapeutic applications, potentially for mood disorders.

Abstract

Vaporized N,N-Dimethyltryptamine (DMT) has a short duration and simple application, prompting this technique as a new approach for psychedelics' cl...

A Single Belief-Changing Psychedelic Experience Is Associated With Increased Attribution of Consciousness to Living and Non-living Entities

Frontiers in Psychology  – March 28, 2022

Summary

Psychedelic experiences profoundly reshape how people perceive consciousness. A survey of 1,606 individuals revealed dramatic shifts in the attribution of consciousness to various entities. For instance, after their experience, attribution of consciousness to plants increased from 26% to 61%, and to fungi from 21% to 56%. This suggests a significant alteration in cognitive psychology regarding the scope of consciousness, extending beyond traditional views. These shifts, observed within the field of Psychedelics and Drug Studies, were lasting, unlike changes in superstitious beliefs.

Introduction Although the topic of consciousness is both mysterious and controversial, psychedelic drugs are popularly believed to provide unique i...

Spontaneous Spiritual Awakenings: Phenomenology, Altered States, Individual Differences, and Well-Being

Frontiers in Psychology  – August 19, 2021

Summary

Spontaneous Spiritual Awakenings, profound altered states of consciousness, are overwhelmingly positive, even when initially challenging. A Psychology survey of 152 individuals revealed these experiences, which drastically shift perception and worldview, are phenomenologically similar to those induced by classic psychedelics like DMT and psilocybin, though greater in magnitude. Personality traits, such as absorption, predict these events. This work, relevant to Phenomenology, Psychedelics and Drug Studies, and even Paranormal Experiences, illuminates how consciousness can profoundly transform individual well-being and development.

From Ego to Death: Validation of the Ego-Dissolution Scale (EDS)

OpenAlex  – July 27, 2022

Summary

Psychedelics like Ayahuasca and Psilocybin profoundly alter the self, offering deep insights and pleasure, challenging psychology's view of the ego. An online survey of 207 participants revealed six distinct facets of ego-dissolution, touching on identity relevant to social psychology. Ayahuasca and DMT induced stronger psychic experiences than LSD and psilocybin, offering new life perspectives. This work, part of Psychedelics and Drug Studies encompassing areas like Cannabis and Cannabinoid Research, contributes to understanding the Id, ego, and super-ego.
