I've come around to the idea of Psilocybin as a therapeutic treatment for PTSD, but only in the context of treatment being administered and monitored by a doctor. Not a fan of any other approach. Don't want it to become the next recreational drug like marijuana. But 'Becoming Cary Grant' did make me rethink my position on using low dose psychedelics as a therapeutic tool for severe mental illness. And I say this as a middle aged guy who has never taken any form of illegal drug in my life, and am so square even my pants say 'regular straight'.
