The title seems a bit misleading. I thought they were talking about LSD or psilocybin. But this is referring to an MDMA-based therapy which I feel is more of a stimulant, or at least is used as one more often than it's used as a psychedelic and it's an amphetamine.
It's astonishing. I had a hard time wrapping my head around this...he is quite literally being REWARDED for failure. I knew the world wasn't fair, but wow.
