Psilocybin mushrooms feel like a modern discovery, but humans have been eating them ceremonially for thousands of years. The story runs from prehistoric rock art through Aztec temples, a 1957 magazine article, a moral panic, and finally today's scientific renaissance.
Ancient roots
Rock art in the Sahara dated to ~7,000–9,000 years ago appears to depict mushroom-headed figures. In Mesoamerica the evidence is unambiguous: the Aztecs called psilocybin mushrooms teonanácatl — "flesh of the gods" — and used them in religious ceremony for centuries before Spanish colonizers suppressed the practice and drove it underground, where it survived quietly for 400 years.
1957: the West finds out
Amateur mycologist R. Gordon Wasson traveled to Oaxaca and participated in a ceremony led by Mazatec curandera María Sabina. His account, published in Life magazine as "Seeking the Magic Mushroom," introduced millions of Americans to psilocybin. Swiss chemist Albert Hofmann — of LSD fame — isolated and synthesized psilocybin from Wasson's samples the following year.
Boom, ban, and backlash
Through the 1960s, psilocybin research flourished (including the famous Harvard experiments) and recreational use spread. The backlash landed in 1970: the U.S. Controlled Substances Act classified psilocybin as Schedule I, freezing legitimate research for three decades.
The renaissance
Since the 2000s, institutions like Johns Hopkins and NYU have restarted rigorous psilocybin research, with promising results for depression, end-of-life anxiety and addiction. Oregon and Colorado have legalized supervised use; cities across California have deprioritized enforcement. María Sabina's "little saints" are finally getting their scientific due.
