Since 1970 psychedelics — drugs like psilocybin, MDMA, LSD, and DMT — have been categorized as Schedule I drugs in the United States. By definition, that means they have no accepted medical use.
Before then, some researchers — like psychologist Timothy Leary — advocated for psychedelics. Then their studies came to a grinding halt.
For decades, that meant research on psychedelics was stagnated.
