A psilocybin patient stating her post-treatment suicidal ideation was judged unrelated to psilocybin despite her claiming a link. I've seen up close too many efforts to "protect" psychedelic research. Psychedelics are very promising, but we need to be principled. The notion that psychedelics will save our species is very dangerous as it justifies any effort to protect this research no matter what principles are broken. Too much cult like thinking even among scientists.

I regret being interviewed for this article about psychedelics & Prince Harry w Daily Mail (& now copy cat articles also quote me). Many of my words were distorted or out of context. Biased & distasteful. dailymail.co.uk/health/article… I should have declined any story with this backdrop. I have no interest commenting on any family's internal issues. Distasteful. Made it clear I wasn't commenting on them specifically. I thought I could provide nuance & balance but that didn't happen.

When I warn against being a psychedelic science guru, I don’t mean sharing expertise w/ public e.g. Neil deGrasse Tyson as an astrophysics “guru." Rather I mean going beyond the basis of a mental health professional/scientist & teaching patients pseudo-religious explanations. Experts should inform the public. Professors should profess. But the temptation of the practitioner to distort psychedelic therapy into their own metaphysical or quasi-religious framework is going to pose major challenges for the future of this field.
