Hub at Oxford for Psychedelic Ethics

Psychedelic ethics for bench, bedside and bill.

HOPE is an interdisciplinary research group working on the ethics of psychedelics in research, in the clinic, and in law and policy: we bring scientists, clinicians, and lawmakers together to develop practical, consensus-driven guidance for ethically-informed practice as psychedelics move into medicine and society.

About

Evidence-informed ethics for ethically-informed practice.

HOPE — the Hub at Oxford for Psychedelic Ethics — is an interdisciplinary research group working on the ethics, law, and social policy of psychedelics. Established at Oxford in 2023 and now hosted at Johns Hopkins, it brings together researchers, policymakers, and practitioners to develop ethical frameworks for the responsible integration of psychedelics into medicine and society. What began as a 2023 gathering at Oxford has since grown into an international collaboration spanning Oxford, Johns Hopkins, and partner institutions, whose researchers have helped set the global agenda for the field.

Our work addresses questions including informed consent in clinical trials, integration practices, research oversight, therapeutic boundaries, and policy development across medical and non-medical contexts. We favour collaborative, consensus-driven scholarship that translates ethical analysis into practical guidance, expressed through our published work, our convenings, and contributions such as our response to a Congressional Request for Information on psychedelic medicine.
