"Psilocybin Trends in States That Decriminalized Use" jamanetwork.com/journals/jama/…

New findings from a pilot randomized trial of psilocybin for smoking cessation are now published in @JAMANetworkOpen. This is one of the largest controlled trials of psilocybin for substance use disorder, with promising results! Full paper linked below.

@Josh__Hardman @ExistWell @sdpnayak @JHPsychedelics It was great to see you today!

Great to visit @ExistWell, @sdpnayak, et al. at @JHPsychedelics in Baltimore today.

Our (@zarmeen_z Jared Hinkle @sdpnayak @ExistWell) State of the Art Review on psychedelic medicine is now out in @bmj_latest. A few thoughts on why we wrote it the way we did. 🧵

Do the people in the room for psychedelic sessions change the psychedelic experience? In this analysis across multiple studies, the answer depends on whether the study is on a clinical or healthy population. Analysis led by @SeanPGoldy & @sdpnayak

‼️New paper‼️ Does your psychedelic facilitator shape your experience? This is a key question considering that the psychedelic experience can predict treatment outcomes. We analyzed the largest dataset of its kind, featuring 20yrs+ of psilocybin trials from @JHPsychedelics

The term "PSYCHEDELICS" can cover a broad set of substances, which people define differently. Risks vary by substance, so worth specifying which one(s) you mean whenever you use the term. New article led by Jared Hinkle (MD/PhD), w/ @willjwchoi (med student and researcher) & me:

New pilot study from Johns Hopkins finds psilocybin-assisted treatment was associated with significant and sustained benefits in post-treatment Lyme disease, including improved mood, fatigue, sleep, pain, and quality of life for up to 6 months. More research is needed to confirm. Read more below👇

Please consider taking this if you qualify and spreading widely!

Have you had separate experiences with psychedelics and cannabis (i.e., a time when you experienced psychedelics and a separate time when you experienced cannabis)? If so, take our survey! Your responses help us understand these compounds better, so that we can continue to expand the science of psychedelics and knowledge about their risks and benefits. tinyurl.com/psyches-cannab…

Debate continues over when psychological support crosses into psychotherapy in psychedelic trials—and much of it reflects unclear definitions rather than true disagreement. Clarifying and operationalizing these constructs is essential if we want to measure when they occur and rigorously test their roles in safety and efficacy.
