Ethics and ego dissolution: the case of psilocybin
Open accessAbstract
Despite the fact that psychedelics were proscribed from medical research half a century ago, recent, early-phase trials on psychedelics have suggested that they bring novel benefits to patients in the treatment of several mental and substance use disorders. When beneficial, the psychedelic experience is characterized by features unlike those of other psychiatric and medical treatments. These include senses of losing self-importance, ineffable knowledge, feelings of unity and connection with others and encountering ‘deep’ reality or God. In addition to symptom relief, psychedelic experiences often lead to significant changes in a patient’s personality and worldview. Focusing on the case of psilocybin, we argue that the peculiar features of psychedelics pose certain novel risks, which warrant an enhanced informed consent process–one that is more comprehensive than what may be typical for other psychiatric medications. We highlight key issues that should be focused on during the consent process and suggest discussion prompts for enhanced consent in psychedelic psychiatry. Finally, we respond to potential objections before concluding with a discussion of ethical considerations that will arise as psychedelics proceed from highly controlled research environments into mainstream clinical psychiatry.

Psychedelic-assisted therapy has been shown to enhance perceptions and ability to find meaning in one's life and lead to positive alterations of the self, despite being artificially induced.
“Psychedelic-assisted therapy has been shown to enhance perceptions and ability to find meaning in one's life (Smith and Sisti 2020), while leading to positive alterations of the self (Baggott et al. 2016), despite being artificially induced.”
From Authenticity and Love Drugs: Insights from Psychedelic Therapy (2026) · cites this paper as Smith and Sisti 2020
In “Personality Change and Neurobiology of Psilocybin-Assisted Psychotherapy” (page unavailable), Smith and Sisti report that most subjects in several studies ranked psilocybin treatment among the most meaningful events of their lives and describe changed perceptions of connection. This supports the claim about meaningful experiences, but does not establish an enhanced ability to find meaning in life. The separate claim about positive alterations of the self is cited to Baggott et al., not to Smith and Sisti. (LLM, conf=0.82)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
