Psychedelic Science - Between Personal Growth, Autonomy, and (Over-) Medicalization

The resurgence of interest in psychedelic substances for mental health and substance use disorder treatment in recent years has opened the doors for dialogues related to potential benefits and harms. The Global Drug Survey 2019 has shown that people who had previously used psychedelic substances were more likely to consider these substances to assist psychotherapy when compared to those without such an experience. A low dose of LSD or psilocybin was the preferred choice when offered alongside other substances and different doses. While mental health is the gateway to psychedelic medicine, recreational use of psychedelic substances to seek altered states of mind that may or may not be associated with spirituality and personal growth is still the most prevalent form of use as of today. In the U.S., several cities have launched educational campaigns such as Decriminalize Nature that aim to decriminalize entheogenic plants and to restore humans' root connection to nature to improve health and well-being. This presentation will discuss how these developments fit within the broader context of drug policy reform and how future policies should conceptualize safe spaces for the use of psychedelic substances both in recreational and therapeutic settings. Finally, a critical reflection will assess how to prevent that (over-)medicalization negatively impacts the autonomy of marginalized communities.

Translating REBUS: Implications and new evidence of belief updating under psychedelics

Monday, October 28, 18:30 - 19:45, University of Zurich, KOL-F-118

Hannes Kettner, M.Res
Neuropsychologist, Imperial College London

The recently proposed 'Relaxed beliefs under psychedelics' (REBUS) model puts forth a unified mechanistic account of how psychedelics may affect the human mind and brain by interpreting various lines of neurocognitive and psychological findings through the topical theory of the brain as a hierarchical predictive coding machine. In this talk, I will present data related to beliefs and belief stability collected in the context of three different observational naturalistic studies over the past 3.5 years. These will include results showing changes in explicit global belief structures (specifically, beliefs pertaining to the nature of reality, consciousness, concepts such as free will, and non-naturalistic 'magical' beliefs), psychological constructs related to belief stability, and preliminary evidence suggesting improved Bayesian belief updating in individuals under the influence of a psychedelic. Finally, I will suggest a framework which aims to plausibly put in relationship the 'epistemic shock' accompanying acute destabilisation of high-level beliefs and long-term psychological outcomes, touching also upon the concepts of psychedelic integration and 'meaning-making'.

Hannes Kettner has studied biosciences, philosophy, and psychology in Heidelberg and holds a MSc in Neuropsychology from Maastricht University. He is currently a member of the Center for Psychedelic Research at Imperial College London. His work focuses on how cognitive and mental health research can be integrated into and informed by naturalistic settings of psychedelic and plant medicine use.

Psychedelic Plant Teachers

Monday, May 13, 18:30 - 19:45, University of Zurich, KOH-B-10 (PLEASE NOTE DIFFERENT LECTURE HALL)

Anthropologist and Author

An anthropologist tries to reconcile science and Amazonian plant knowledge, drawing concepts from both sides. Plants like ayahuasca and tobacco can act both as “psychedelics” , meaning mind-revealing, and as “teachers", in that they allow knowledge to be gained. But working with plant teachers is tricky, and has ups and downs. Beacuse they are mind-revealing, the experience one can have after ingesting them depends on who one is. Ultimately, when working with plant teachers, going back and forth between systems of knowledge is a slow process that can be rewarding, but that also has its perils.

Die analytische Psychologie nach C.G. Jung und die Phänomenologie von Ayahuasca-Erfahrungen: Unbewusste und affektive Dynamiken

Monday, March 4, 18:30 - 19:45, University of Zurich, KOL-F-118

Dr. med. Heiner Dörfler
Psychiater und Ayahuasca-Forscher

Der Schweizer Psychiater Carl Gustav Jung (1875-1961) prägte mit seinen Begriffen, Ideen und Theorien die populärwissenschaftliche Psychologie des 20. Jahrhunderts, in der akademischen Welt blieb er jedoch oft umstritten. Wesentlich waren für Jung spirituelle und transzendente Dimensionen des Menschen, er suchte nach Tiefe und Sinnerfahrungen in der menschlichen Seele. Mit seinem Werk wirkte er in die Bereiche von Religionspsychologie, Philosophie, Astrologie und Ethnologie hinein. Die Innenschau war für Jung der Schlüssel zu Selbsterkenntnis und Individuation. Im psychotherapeutische Prozess ging es für Jung darum, sich mit Komplexepisoden, unter besonderer Berücksichtigung der affektiven Ebenen, auseinanderzusetzen. In einem schöpferischen Prozess mit dem Einbezug von Träumen und inneren Bildern sollte im Analysanden ein Entwicklungs- und Wandlungsprozess angestossen werden.

Ayahuasca ist ein traditioneller psychotroper Tee aus dem Amazonasgebiet, der in den letzten Jahren ein zunehmendes wissenschaftliches Interesse erweckt. Trinkende berichten von Ayahuasca als Werkzeug, unentdeckte Gebiete des menschlichen Geistes zu erforschen. Unter der Wirkung von Ayahuasca kommt es zu einem breiten Spektrum psychischer und physischer Phänomene, darunter beispielsweise das Wiedererleben autobiografischer Erinnerungen, das intensive Fühlen körperlicher Sensationen, oder auch transpersonale und übersinnliche Erfahrungen. Auch können unangenehme, karthatische Prozesse durchlebt werden, welche in Jungs Worten als Begegnungen und Arbeit mit dem eigenen Schatten beschrieben werden können. In diesem Vortrag möchte sich der Referent mit Parallelen in Jungs Konzepten und der Phänomenologie von Ayahuasca-Erfahrungen auseinandersetzen.
