Do we know that a clinical setting is advantageous or even neutral for these types of treatments?

Ravers/psychedelic community: “it’s the drugs, music, and community, man!”

Clinicians for 50 years while people are suffering immensely: “no.”

Clinicians after 50 years: “okay, we’ll give you the drugs in our clean room.”

Maybe clinical settings are fine, and surely the way to find out is by doing rigorous science, but it’s very possible still that the medical community is wrong on this and thousands of years of communal drug/dance/music rituals were “more right.”
