/8 Lastly, a critical finding across these two studies is related to psychedelic risks: The frequency of HPPD-type visual aftereffects at the 4-week endpoint was more than doubled in adolescents, with 50% (30 of N=60 who answered this question), reporting at least one symptom.

Had a fantastic time connecting and presenting my work with David B. Yaden, Brandon, and Michiel van Elk at #ICPR2024! Excited to improve our measurement & understanding of #psychedelics’ subjective effects. Huge thanks to OPEN Foundation for the chance to present at this amazing conference.

Nate Phillips Luiz Pessoa Josh Miller Donald Lynam Good cites in this thread re: brain structure. Studies on task-related activation also suggest null results - see Hyatt et al (2020) and Weiss et al (2021) Brandon in Personality Neuroscience. Lots of problems with this task methodology though (e.g., biorxiv.org/content/10.110…)

There are so many ethical questions facing the growing field of psychedelics. Thank you, HOPE, for bringing us together for a set of vital (and vitalizing) discussions of these topics! Johns Hopkins Psychedelic Research Center Johns Hopkins Berman Institute of Bioethics

Excellent review and consideration of questionnaires in psychedelic research. Bravo David B. Yaden Brandon Sean Goldy and Roland! I want to amplify a few nuggets, including:

👇🏻 Finally! Thanks to David Yaden and collegues for this! 👏🏻👏🏻👏🏻 This is also a relevant paper for psychologists of religion the CSR gang. Congratulations on the paper!

Valuable new laboratory data from n > 200 showing effects of pre-administration mood and personality on acute subjective effects.

New article: Quantitative summary of adverse events in psychedelic studies. We find a favorable safety profile, but with major caveats. Serious adverse events were rare but did occur (esp. in those w/ disorders). We call for improvements to adverse event recording and reporting.
