  • The Ethics of Psychedelic Medicine: a Case for the Reclassification of Psilocybin for Therapeutic Purposes
    THE ETHICS OF PSYCHEDELIC MEDICINE: A CASE FOR THE RECLASSIFICATION OF PSILOCYBIN FOR THERAPEUTIC PURPOSES By Akansh Hans A thesis submitted to Johns Hopkins University in conformity with the requirements for the degree of Master of Bioethics Baltimore, Maryland May 2021 © 2021 Akansh Hans All Rights Reserved I. Abstract Our current therapeutic mental health paradigms have been unable to adequately handle the mental illness crisis we are facing. We ought to ‘use every tool in our toolbox’ to help individuals heal, and the tool we should be utilizing right now is Psilocybin. Although it is classified as a Schedule I drug, meaning that it is believed to have a high potential for abuse, no accepted medical uses, and a lack of safety when used under medical supervision, Psilocybin is not addictive and does not have a high potential for abuse when used safely under medical supervision. For these reasons alone, Psilocybin deserves a reclassification for therapeutic purposes. However, many individuals oppose Psilocybin-assisted psychotherapy on ethical grounds or due to societal concerns. These concerns include: a potential change in personal identity, a potential loss of human autonomy, issues of informed consent, safety, implications of potential increased recreational use, and distributive justice and fairness issues. Decriminalization, which is distinct from reclassification, means that individuals should not be incarcerated for the use of such plant medicines. This must happen first to stop racial and societal injustices from continuing as there are no inherently ‘good’ or ‘bad’ drugs. Rather, these substances are simply chemicals that humans have developed relationships with. As is shown in this thesis, the ethical implications and risks of psychedelic medicine can be adequately addressed and balanced, and the benefits of Psilocybin as a healing tool far outweigh the risks.

    RESEARCH ARTICLE DMT alters cortical travelling waves Andrea Alamia1‡*, Christopher Timmermann2,3‡*, David J Nutt3, Rufin VanRullen1,4†, Robin L Carhart-Harris3† 1Cerco, CNRS Universite´ de Toulouse, Toulouse, France; 2Computational, Cognitive and Clinical Neuroscience Laboratory (C3NL), Faculty of Medicine, Imperial College, London, United Kingdom; 3Centre for Psychedelic Research, Division of Psychiatry, Department of Brain Sciences, Imperial College London, London, United Kingdom; 4Artificial and Natural Intelligence Toulouse Institute (ANITI), Toulouse, France Abstract Psychedelic drugs are potent modulators of conscious states and therefore powerful tools for investigating their neurobiology. N,N, Dimethyltryptamine (DMT) can rapidly induce an extremely immersive state of consciousness characterized by vivid and elaborate visual imagery. Here, we investigated the electrophysiological correlates of the DMT-induced altered state from a pool of participants receiving DMT and (separately) placebo (saline) while instructed to keep their eyes closed. Consistent with our hypotheses, results revealed a spatio-temporal pattern of cortical activation (i.e. travelling waves) similar to that elicited by visual stimulation. Moreover, the typical top-down alpha-band rhythms of closed-eyes rest were significantly decreased, while the bottom- up forward wave was significantly increased. These results support a recent model proposing that *For correspondence: psychedelics reduce the ‘precision-weighting of priors’, thus altering the balance of top-down

  • Classic Serotonergic Psychedelics for Mood and Depressive Symptoms: a Meta-Analysis of Mood Disorder Patients and Healthy Participants
    Psychopharmacology (2021) 238:341–354 https://doi.org/10.1007/s00213-020-05719-1 REVIEW Classic serotonergic psychedelics for mood and depressive symptoms: a meta-analysis of mood disorder patients and healthy participants Nicole L. Galvão-Coelho1,2,3,4,5 & Wolfgang Marx6 & Maria Gonzalez4 & Justin Sinclair4 & Michael de Manincor4 & Daniel Perkins7 & Jerome Sarris4,8 Received: 5 August 2020 /Accepted: 13 November 2020 / Published online: 11 January 2021 # The Author(s) 2021 Abstract Rationale Major depressive disorder is one of the leading global causes of disability, for which the classic serotonergic psyche- delics have recently reemerged as a potential therapeutic treatment option. Objective We present the first meta-analytic review evaluating the clinical effects of classic serotonergic psychedelics vs placebo for mood state and symptoms of depression in both healthy and clinical populations (separately). Results Oursearchrevealed12eligiblestudies(n = 257; 124 healthy participants, and 133 patients with mood disorders), with data from randomized controlled trials involving psilocybin (n = 8), lysergic acid diethylamide ([LSD]; n = 3), and ayahuasca (n = 1). The meta-analyses of acute mood outcomes (3 h to 1 day after treatment) for healthy volunteers and patients revealed improvements with moderate significant effect sizes in favor of psychedelics, as well as for the longer-term (16 to 60 days after treatments) mood state of patients. For patients with mood disorder, significant effect sizes were detected on the acute, medium (2–7 days after treatment), and longer-term outcomes favoring psychedelics on the reduction of depressive symptoms. Conclusion Despite the concerns over unblinding and expectancy, the strength of the effect sizes, fast onset, and enduring therapeutic effects of these psychotherapeutic agents encourage further double-blind, placebo-controlled clinical trials assessing them for management of negative mood and depressive symptoms.

Psychological Medicine. 1 Running head: Post-acute effects of psychedelics Abstract Background: Scientific interest in the therapeutic effects of classical psychedelics has increased in the past two decades. The psychological effects of these substances outside the period of acute intoxication have not been fully characterized. This study aimed to: (1) quantify the effects of psilocybin, ayahuasca, and LSD on psychological outcomes in the post-acute period; (2) test moderators of these effects; and (3) evaluate adverse effects and risk of bias. Methods: We conducted a systematic review and meta-analysis of experimental studies (single-group pre-post or randomized controlled trials) that involved administration of psilocybin, ayahuasca, or LSD to clinical or non-clinical samples and assessed psychological outcomes ≥24 hours post- administration.

Ayahuasca is a South American psychoactive plant brew used as traditional medicine in spiritual and in cultural rituals. This is a review of the current understanding about the pharmacological mechanisms that may be interacting in ayahuasca. Searches were performed using PubMed, PsycINFO, and Web of Science databases and 16 papers were selected. As hypothesized, the primary narrative in existing research revolved around prevention of deamination of N,N-dimethyltryptamine (N,N-DMT, also referred to as DMT) by monoamine oxidase inhibitors (MAOIs) in ayahuasca. Two of the constituents, DMT and harmine, have been studied more than the secondary harmala alkaloids. At present, it is unclear whether the pharmacological interactions in ayahuasca act synergistically or additively to produce psychoactive drug effects. The included studies suggest that our current understanding of the preparation’s synergistic mechanisms is limited and that more complex processes may be involved; there is not yet enough data to determine any potential synergistic interaction between the known compounds in ayahuasca. Our pharmacological understanding of its compounds must be increased to avoid the potential risks of ayahuasca use.
