So... this clinic was not entirely unlike what you're proposing w/ DMT.
FWIW, the results were incredible. I was effectively "cured." But unfortunately my insurance changed, and it became no longer covered, and I couldn't afford the $2000 every six weeks for the treatment anymore. And it's not super convenient to take two hours off from work to go to the trip-sitter's to get the treatments.
I hope that they figure out what it is in psychadelics that make them effective at treating stuff like depression and PTSD and make it more accessible because it seems like there's so much potential there.
(Also: fuck Elon Musk for making Ketamine a punchline)
