    Psychedelics are increasingly being studied and used in clinical and therapeutic contexts, prompting renewed ethical and regulatory debate. Claims of psychedelic exceptionalism—whether “negative,” portraying psychedelics as uniquely risky and thus requiring stricter oversight, or “positive,” portraying them as uniquely beneficial and thus exempt from ordinary ethical rules—have become common. In a recent article, we argued that while psychedelics may involve distinctive constellations of feature…Read more

    Using curiosity to render the invisible, visible
    Theoretical Medicine and Bioethics 45 (4): 251-259. 2024.
    Virtues commonly associated with physicians and other healthcare professionals include empathy, respect, kindness, compassion, trustworthiness, and many more. Building upon the work of Bortolloti, Murphy-Hollies, and others, I suggest that curiosity as a virtue has an integral role to play in healthcare, namely, in helping to make those who are invisible, visible. Practicing the virtue of curiosity enables one to engage with and explore the experiences of patients and contributes toward building…Read more

    Defusing the legal and ethical minefield of epigenetic applications in the military, defence and security context
    with Gratien Dalpe, Katherine Huerne, Charles Dupras, Nicole Palmour, Eva Winkler, Karla Alex, Maxwell Mehlmann, John W. Holloway, Eline Bunnik, Harald König, Isabelle M. Mansuy, Marianne G. Rots, Cheryl Erwin, Alexandre Erler, Emanuele Libertini, and Yann Joly
    Journal of Law and the Biosciences 10 (2): 1-32. 2023.
    Epigenetic research has brought several important technological achievements, including identifying epigenetic clocks and signatures, and developing epigenetic editing. The potential military applications of such technologies we discuss are stratifying soldiers’ health, exposure to trauma using epigenetic testing, information about biological clocks, confirming child soldiers’ minor status using epigenetic clocks, and inducing epigenetic modifications in soldiers. These uses could become a reali…Read more

    Informed Consent Documents from Psychedelic Clinical Trials: A Descriptive Ethical Analysis
    with Caleigh Propes, Marianna Graziosi, Kyle Patch, and David B. Yaden
    AJOB Empirical Bioethics 16 (4): 247-266. 2025.
    Background Classic psychedelics, such as psilocybin and LSD, evoke certain kinds of altered states of consciousness. Specific features of the experience, such as its allegedly ineffable nature, have been discussed as posing challenges to the informed consent process. A growing call for tailored informed consent documents (ICDs) in the psychedelic bioethics literature raises the question of how closely ICDs used in contemporary psychedelic trials reflect the concrete suggestions and proposals off…Read more

    Valuing the Acute Subjective Experience
    Perspectives in Biology and Medicine 67 (1): 155-165. 2024.
    ABSTRACT:Psychedelics, including psilocybin, and other consciousness-altering compounds such as 3,4-methylenedioxymethamphetamine (MDMA), currently are being scientifically investigated for their potential therapeutic uses, with a primary focus on measurable outcomes: for example, alleviation of symptoms or increases in self-reported well-being. Accordingly, much recent discussion about the possible value of these substances has turned on estimates of the magnitude and duration of persisting pos…Read more

    A role for kindness and curiosity in healthcare
    Journal of Medical Ethics 50 (8): 578-579. 2024.
    In his paper ‘Ethical problems with kindness in healthcare’, Jesudason sets out an interesting examination of the concept of kindness, arguing that it poses significant ethical challenges due to its discretionary nature. I suggest that kindness, a concept difficult to define, may still have a role to play in healthcare. Different treatments of kindness show us that it need not be discretionary, and that kind care can be provided to all. Finally, curiosity may also have a role to play in medicine…Read more

    Psychedelics, Meaningfulness, and the “Proper Scope” of Medicine: Continuing the Conversation
    with Kyle Patch, Brian D. Earp, and David B. Yaden
    Cambridge Quarterly of Healthcare Ethics 33 (4): 601-607. 2024.
    Psychedelics such as psilocybin reliably produce significantly altered states of consciousness with a variety of subjectively experienced effects. These include certain changes to perception, cognition, and affect,1 which we refer to here as the acute subjective effects of psychedelics. In recent years, psychedelics such as psilocybin have also shown considerable promise as therapeutic agents when combined with talk therapy, for example, in the treatment of major depression or substance use diso…Read more

    A prominent critique of cognitive or athletic enhancement claims that certain performance‐improving drugs or technologies may ‘cheapen’ resulting achievements. Considerably less attention has been paid to the impact of enhancement on the value of moral achievements. Would the use of moral enhancement (bio)technologies, rather than (solely) ‘traditional’ means of moral development like schooling and socialization, cheapen the ‘achievement’ of morally improving oneself? We argue that, to the exten…Read more

    Distinctive But Not Exceptional: The Risks of Psychedelic Ethical Exceptionalism
    with Brian D. Earp, Kyle Patch, and David B. Yaden
    American Journal of Bioethics 25 (1): 16-28. 2025.
    When used clinically, psychedelics may appear unusual or even unique when compared to more familiar or long-standing medical interventions, prompting some to suggest that the ethical issues raised may likewise be exceptional. If that is correct, then perhaps psychedelics should be treated differently from other medical substances: for example, by being subjected to different ethical or evidentiary standards. Alternatively, it may be that psychedelics have more in common with various existing med…Read more

    Psychedelic Treatment with Psilocybin: Addressing Medical Malpractice Risk and Physicians’ Concerns
    with Maxwell Brodie, Sue-Ling Chang, Pierre Deschamps, Jean-Sébastien Fallu, Houman Farzin, Johanne Hébert, Jean-François Stephan, Michel Dorval, Yann Joly, and for the P3A Study Group
    Journal of Law, Medicine and Ethics 53 (2): 256-264. 2025.
    Psychedelic treatment with psilocybin is receiving increased attention following clinical trials showing it may help treat end-of-life anxiety, depression, and several other conditions. Despite this, physicians may be reluctant to prescribe psilocybin and carry out psilocybin treatment because of the stigma surrounding psychedelics and the potential for medical malpractice liability. This paper explores whether psilocybin treatment gives rise to a risk of medical malpractice liability for physic…Read more

Hannikainen, Mette Leonard Høeg, Sean Clancy, Khaleel Rajwani, Emma C. Gordon, Giovanni Spitale, Neil Levy, Keisha Ray, Yuria Celidwen, Ilina Singh, Julian Savulescu, David Bryce Yaden, and Brian D. Earp
    Philosophical Psychology 38 (7): 3340-3383. 2025.
    The current revival of interest in classic psychedelics and other psychoactives such as ketamine and MDMA, coupled with changes to their regulatory status in many jurisdictions, necessitates rigorous ethical guidelines both within and beyond clinical and scientific contexts. This paper examines crucial ethical, philosophical, and policy considerations needed to ensure psychedelic use across various settings remains equitable, beneficial, consensual, and safe, with appropriate accountability mech…Read more

    Enhanced independence: De-biasing processes in psychedelic research and beyond
    with Rebecca Ehrenkranz and David B. Yaden
    Research Ethics 22 (1): 57-80. 2026.
    Randomized controlled trials (RCTs) are considered the gold standard for demonstrating the efficacy of a treatment or intervention; however, the RCT study design alone is insufficient to prevent all forms of bias. In this paper, we review conflicts of interest and other biases that pose challenges to the methodological rigor of psychedelic RCTs, and explore recommended bias mitigation measures. We focus on biases of special relevance to psychedelic RCTs and methods of mitigating bias that we bel…Read more
