Reframing Psychedelic Regulation: Tools, not Treatments

In this new article, we propose to regulate psychedelics as psychotherapeutic treatment tools rather than as treatments in their own right.

The use of anesthetics as treatment tools in surgery is a useful analogy.

Also - inviting all the other experts from naturalistic studies is very challenging and requires more time, so we hope this would be next step. This requires to bring together also the voices of psychonauts, retreat providers, curanderos, neo-shamans, DJs, and so on - and hence a much larger study

Indeed, while I am a fan of naturalistic studies, this was a strategic decision to narrow it to clinical studies. The reason is that we wanted to emphasise the importance of context in psychiatry - where it is the least clear. Opening it up to a wider search would have diluted the main goal.

Psychedelics, Wheat, and Rhizomes How do psychedelics spread, and how do they affect human societies?

Many thanks to @leorroseman.bsky.social for his musings on psychedelics diffusion during our b2b (boat-to-boat) call.

It sparked some thoughts, below (post includes a link to Leor’s excellent ICPR talk):

A perspective piece of mine of paradigmatic tension between biological psychiatry and psychedelic therapy, as reflected in the FDA regulatory process (yes, it takes that long to publish in academic journals, even a small opinion piece).

My academic work moves into art. It's a huge honour to perform with Ripples Collective - a group of Palestinian and Israeli activists and artists. The performance is called Collective Liberation Ritual, and carries the audience through a process from grief to solidarity and empowerment. More to come
