PhD student in Bioethics & Health Policy at @JohnsHopkinsSPH @bermaninstitute | psychedelic ethics 🌱, research ethics

Working on getting a bibliography of sorts for psychedelic ethics/philosophy papers together - sharing in case it comes in useful for anyone else! Ongoing project & please feel free to let me know if I've missed something 🌿 katcheung.com/psychedelic-et…

Meeting with scientists, clinicians, and bioethicists at @JHUBloombergCtr to discuss practical ethical guidelines for clinical applications of psychedelics. Meeting led by @eddietalksdrugs & @Katherine_Chg with @briandavidearp and I glad to see @psychedelethics doing applied work

We are thrilled to share a major milestone for the Johns Hopkins Center for Psychedelic and Consciousness Research: @CeydaSayali, PhD, has received an R01 award from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) — the first R01 awarded to an investigator at our Center. The study will test a novel treatment approach for alcohol use disorder (AUD) combining psilocybin with personalized repetitive transcranial magnetic stimulation (rTMS). This is the first study to investigate this combination for AUD, with rTMS targets individualized using fMRI to identify each participant’s brain circuitry involved in regulating alcohol craving. Using fMRI and TMS-EEG, the study will also examine how this combined intervention changes the neural mechanisms underlying craving, cognitive control, and treatment response. By integrating psychedelic pharmacology, personalized brain stimulation, and multimodal neuroscience, this work aims to advance both treatment development and our understanding of how brain-based interventions can reduce problematic alcohol use. Congratulations to Dr. Sayalı and the research team on this important achievement and exciting new direction for the Center.

The first completely on-site preclinical animal study from @JHPsychedelics. An immensely valuable collaboration with Division of Behavioral Biology. So grateful that I got to lead it and work with what can only be called the dream team! Unroll the tweet below for deets 📜
New paper led by @PraachiTiwari, a former postdoc in @TheYadenLab, now faculty at Div of Behavioral Bio & @JHPsychedelics (also w/ @CassieMoorePhD, Brian Jenkins, Elise Weerts, me). We examined how psilocybin affects a broader range of spontaneous behaviors in rats than HTR...

New paper – Validating and Creating a Short-Form of the Persisting Effects Questionnaire: A Measure of Positive and Negative Outcomes from Psychedelic Experiences The Persisting Effects Questionnaire (PEQ) is a measure of self-reported positive and negative effects from psychedelic experiences. While commonly used, the PEQ has never been formally validated, and is time-intensive and complex for both participants and researchers. Using a multi-study approach, CPCR researchers created and validated the Persisting Effects Questionnaire – Short Form (PEQ-SF), a scale that is more easily understood and reduces burden for study teams and participants.

Representing @TheYadenLab at @JHPsychedelics & @psychedelethics at @FDA. Postdoc Eddie Jacobs @eddietalksdrugs spoke to how the evidence on psychedelic treatments comes from clinical trials, so those safeguards should be used for initial roll-out, to be adjusted based on data…

Psychedelic treatments are getting leaner as they approach licensing. Our (@IanRou of @PsyPANglobal, @HattiWells, and @drrosalindwatts) new Perspective in @TheCJPsych argues this gives us (more) reason to pay attention to patients’ social/relational environments🧵

Great article in Scientific American on the Hopkins Post Psychedelic Difficulties Clinic!
As psychedelic therapies expand, new clinics treat uncommon long-term harms spklr.io/6019ERHoz

Congratulations to Dr. @PraachiTiwari on her promotion to faculty at the Johns Hopkins University School of Medicine! Dr. Tiwari joins the Division of Behavioral Biology and the Center for Psychedelic and Consciousness Research, where she will conduct both preclinical neuroscience and clinical studies to explore translational research on psychedelics.

We are seeking healthy individuals to take part in a Johns Hopkins research study. The study will look at the effects of psilocybin, a psychedelic drug, with pindolol (a medication that blocks a serotonin receptor). The study aims to understand the mechanisms in the brain responsible for the changes in perception induced by psilocybin. Participation will involve two dosing sessions at the Johns Hopkins Bayview campus. Contact us at psilblock@jh.edu for more information or apply at jhmi.co1.qualtrics.com/jfe/f… Postdoc Contact Information: Zarmeen Zahid, Ph.D., zzahid2@jh.edu Principal Investigator: Sandeep Nayak, M.D. Protocol: IRB00478908

Oregon’s current psilocybin services program offers an important early case study for other regions looking to facilitate access to psychedelics. In a recent paper, CPCR researchers analyzed the first full year of data from the Oregon Health Authority, examining how Oregon’s policy has balanced safety and access to psychedelics outside of clinical settings.

The first full year of data collected under SB 303 from Oregon's psilocybin services was recently published. With @CaleighPropes & @ExistWell, we examine this data to give a preliminary picture as to how safety and access are being balanced in Oregon’s psilocybin services.

3) The lack of comprehensive data on the full range of safety issues that may be occurring prohibits a complete assessment of the safety of psilocybin services in service center contexts.

Looking forward, systematic collection of adverse event and outcome data will be essential!

Atlantic article discussing current & novel psychedelics, emphasizing parameters like expectancies, context, compound, dose, and beyond. There is SO MUCH scientific work to do in this area to improve on preliminary work & explore altering variables that have not yet been tested!
For thousands of years, humans have searched nature for mind-altering substances through a process of trial and (sometimes fatal) error, @andersen reports—but scientists are now trying to create lab-made, customizable psychedelics: theatlantic.com/health/2026/…
