I'm sure it's nothing like a panacea, but I've lost count of the times in which getting some context behind a report of a bad experience shows recklessness or just plain old bad decisions.
It also works the other way around, people even talk about how years of therapy didn't help but psilocybin did, and few seem to consider that maybe it was a combination of both? Perhaps all of that therapy that "didn't help" set the stage for something else.
General problem with anecdata I guess.
