I mentioned in my other comment, but while I did say “this mold” in my initial inquiry, I was thinking more of the method of application than the particular substance.

Thanks for the answer, TIL! For what it’s worth, based on what I remember of the show, going the Walter White route is ill advised.

Ah, I looked it up and accepted “rye bread” without actually reading the name of the fungus, so you’re probably right about that part.

The broomstick myth that I’ve heard does indeed involve substance abuse to achieve an altered state of mind. The broomstick specific part was because apparently some women would put the substance on the end of a broomstick and apply it, shall we say, internally, thinking that this would achieve greater (or perhaps faster) effect. I don’t know whether entheogen was the material in question.

As initially mentioned, I make no claim that this is true, only that I read it a long time ago and never really questioned it.

edit: Forgot to thank you for the clearly knowledgeable response!

On typing this out, I’m suddenly concerned about this being offensive or blatantly false. I never applied critical thought to the story before, as I’m pretty sure I was told it as a relatively young, and more relevantly gullible, man.

Is it true that this mold played a role in the “witches ride broomsticks” stereotype?

edit: Removed redundant word.
