Maybe not, but there are therapists who specialize in guided psychedelic trips who encourage exploration and fear facing. Seems like they'd know how to guide the discovery process.
We need scientific clinical trials conducted without any therapist intervention in order to understand what good these drugs do on their own. All the BS about talk-therapy being necessary for them to work is going to keep them out of the reach of most people. The reality is that psychedelics will quickly put psychiatrists out of business unless the public is convinced they can't take psychedelics safely without a shrink watching over them.
The reality is that they’re currently out of reach for most people, and the only shot at increasing adoption comes with legally sanctioned institutions to help deploy them safely.
