At least at one time, there were messageboards kind of like this one, where people traded information on how to get recreational drugs to do . . . whatever they wanted them to do. I want to say one of them was called something like "Psychonauts," or that was a thing the users called themselves, or . . . something. When I did a Google search all I found was a video game series, so maybe I hallucinated all of that. :p But then, I hear we're not indexed by Google either, which is of course, just fine.
I guess nowadays places like that are on the dark web, which I don't even know how to use, lol. And $20,000 for a couple of vials of N?? Sweet jebus . . . assuming that's USD, that's maybe 18 months' worth of income for me. I guess that tells you the risk D must be running, and how many desperate folks REALLY want to get their hands on some N.
