Also, I don’t why y’all are acting like folks who use things like mdma and ketamine in a medical/therapeutic context haven’t also used them recreationally. It’s different, because the environment, intention, and often the dosage are all different. You taking drugs at a party is not the same, and using absolutist language to say otherwise when there’s actual medical research that contradicts you is an odd choice.
I think questions like this are underappreciated.
I propose that the potential underlying mechanisms of why people behave the way they do are described here, at least in part:

https://en.wikipedia.org/wiki/Thinking,_Fast_and_Slow
I think it's useful to observe how people, particularly intelligent people, interact with these ideas, and the inherent uncertainty involved.
Are people curious about how nature plays out, or are they tied in some way to nature being a particular way? Are they willing to discuss these ideas, and defend their beliefs, or is there something subconsciously repulsive about certain beliefs that renders them unable to discuss it rationally, but instead forces them to revert to defensive techniques like appeal to authority or popular tribal axioms.
Is uncertainty acceptable?
Otherwise, the big advantage of getting a nurse to do it is that they are in a position to treat you if one of the rare but potentially fatal side effects pops up.
