Someone in the notes brought up "Fear and Loathing in Las Vegas", and they're right that that is a bit of an interesting complication, and so I think it's probably worth adding an explanation for people who are confused.
The book "Fear and Loathing in Las Vegas" (and the movie that was based off of it) mentions "adrenochrome" in the context of recreational drug use – which, to be clear, is not a thing the adrenochrome has ever been used for, or even could be used for. This is like if a book or movie talked about "snorting hydrocortisone at the club".
What seems to have happened, as best I understand it, is: "Fear and Loathing in Las Vegas" was written by Hunter S. Thompson, who did absolutely spend time in deeply creepy far right social circles, including social circles with legit white supremacists and neo-Nazis, because he was a journalist, and was writing about the dark side of various counter cultural movements of the late 1960s and 70s, many of which absolutely had a white supremacist fringe. He seems to have confused the "adrenochrome" that he was occasionally hearing about with one of the irl stimulant drugs that was actually being used by these groups (probably dextroamphetamine), and thought that "adrenochrome" was just another street name for an irl recreational drug.
If you encounter someone talking about "adrenochrome" as though it is a street name for a recreational stimulant that has basically the same effects as dextroamphetamine, they are probably thinking of the drug as it is portrayed in "Fear and Loathing in Las Vegas", and they are not necessarily a neo-Nazi.
IF, on the other hand, you encounter someone talking about adrenochrome in a context which implies that it has anything to do with remaining young, or that it's extracted from the blood of kidnapped children, or that it's used only by "the Elites", or anything else even remotely in that direction, that's 100% neo-Nazi shit, or, best case, sometimes it's neo-Nazi shit that has been filtered through Qanon.
Please don't fall into the trap of "this one movie used the term adrenochrome to refer to a different recreational drug, so idk, maybe this person who wrote about Hillary Clinton taking adrenochrome is thinking of that." In my experience, the vast majority of uses of this term are using it in the neo-Nazi / white supremacist sense, not in the "idk I think it's a street name for an upper, maybe?" sense. "Maybe they're just thinking of 'Fear and Loathing in Las Vegas'" is the adrenochrome equivalent of "maybe they're tagging this post 88 because it's a Chinese lucky number". It's possible, but it's rare, and context clues and common sense should pretty easily sort out the two uses from each other.
