The story of how psilocybin mushrooms came to the attention of the modern world is, in large part, the story of one man and one trip to Oaxaca. In June 1955, R. Gordon Wasson, an amateur ethnobotanist and a vice president at the bank J. P. Morgan, became the first outsider to participate in a Mazatec mushroom ceremony. What happened that night, and what followed, set the modern history of psilocybin in motion.
The story is more complicated than the heroic-discovery framing it usually gets. It involves real ethnographic work, a famous magazine article that altered the trajectory of an indigenous tradition, and consequences for the people whose ceremony Wasson documented that he did not foresee. It is worth telling with all three of those things in view, because the flattering version leaves out the part that matters most.
Before Wasson, what the West knew
By the middle of the twentieth century, almost nothing about Mesoamerican mushroom use was widely known in the West. Sixteenth-century Spanish chroniclers had recorded the existence of teonanacatl, often translated as the flesh of the gods, mushrooms used by the Aztecs in religious contexts. The Spanish suppressed the practice as part of a broader campaign of religious persecution. By the time anthropologists in the early twentieth century took an interest, most assumed the tradition had been lost entirely.
A series of botanical and anthropological reports starting in the 1930s suggested otherwise. Robert Weitlaner, an Austrian-Mexican engineer with ethnographic interests, witnessed mushroom use in Oaxaca in 1936. The Harvard botanist Richard Evans Schultes traveled to the region in 1938 and identified some of the species being used. But these reports stayed largely within specialist circles and never reached a broad audience. The knowledge existed. It just had not escaped the academy, and the wider world had no idea.
The Wassons' project
Robert Gordon Wasson and his wife Valentina, a pediatrician of Russian origin, had developed a deep interest in the cultural history of mushrooms, which they called ethnomycology. The interest was driven partly by Valentina's observation that Russians and other Slavic peoples seemed to have a markedly different relationship with mushrooms than English-speakers did. Where the English-speaking world tended toward what the Wassons called mycophobia, a suspicion and distaste, Slavic cultures had a long and affectionate engagement with fungi.
The Wassons spent years investigating this cultural divide, and in the process became aware of the Mesoamerican reports. They began traveling to Oaxaca in the early 1950s, trying to make contact with people who might still practice the old ceremonies. This was not a casual jaunt. It was the culmination of a genuine, sustained scholarly obsession, which is part of what makes the eventual consequences so complicated to judge.
The velada with Maria Sabina
In June 1955, Wasson and his colleague Allan Richardson were in the Mazatec town of Huautla de Jimenez, in the Sierra Mazateca of Oaxaca. Through local contacts they were introduced to Maria Sabina, a curandera, a traditional healer, who held all-night healing ceremonies called veladas in which she and the participants consumed mushrooms.
On the night of June 29 to 30, 1955, Sabina conducted a velada in which she allowed Wasson and Richardson to take the mushrooms alongside her. The ceremony took place in her home, in the dark, carried by her chants and prayers. Wasson later described the experience as among the most profound of his life. He believed he was the first outsider, at least in modern times, to have taken part in such a ceremony as a full participant rather than a passive observer.
Whether first is the right word is debatable, since other Westerners had certainly observed Mesoamerican mushroom use before, and the question of who participated as opposed to merely watched depends on how you define the criteria. What is not debatable is what Wasson did next, which is the hinge on which the whole story turns.
"Seeking the Magic Mushroom"
In May 1957, Life magazine published Wasson's first-person account of the Huautla velada under the title "Seeking the Magic Mushroom." Illustrated with Richardson's photographs, it ran across seventeen pages and reached a mass American audience. By the standards of mid-century journalism it was an extraordinary piece of writing, vivid, respectful in tone, and focused on the spiritual dimensions of the experience. For most readers it was the first they had ever heard that such a thing existed.
The article also did something Sabina and her community had not anticipated. It made Huautla a destination. Within months, foreigners began arriving in the village in search of the mushrooms. The trickle became a flood through the 1960s as the counterculture expanded. Bob Dylan, John Lennon, and Mick Jagger were all rumored to have visited, and while many of the rumors were probably untrue, the presence of large numbers of seekers was entirely real. A single magazine article had rerouted the future of a town.
For Sabina and the Mazatec community, the consequences were profound and largely negative. The ceremony she practiced was not designed for tourists. It was a healing tradition embedded in a specific cultural and religious context. The arrival of outsiders in large numbers, often with little understanding or respect, disrupted the practice and exposed Sabina herself to social and economic pressure. She was eventually arrested by Mexican authorities, her house was burned by some in her own community who blamed her for the disruption, and she lived her later years in poverty. She told later visitors that after the foreigners came, the mushrooms had lost their power.
Wasson's legacy
Wasson continued his ethnomycological work for decades, publishing extensively on the cultural history of psychoactive mushrooms and other plants. He was instrumental in connecting Western researchers to the chemistry and pharmacology of the substance, including Albert Hofmann, who synthesized psilocybin from samples Wasson provided. In a real sense, the entire research field that followed has a thread running back to his expedition.
His scholarly contributions were substantial. His ethnomycological method, treating cultural attitudes toward fungi as a serious object of study, was genuinely influential, and his introduction of psilocybin to Western science enabled an entire field of research. But his role in the disruption of the very tradition he documented is also part of his legacy, and one he came to regret. He acknowledged in later writings that he had not anticipated the consequences of the Life article, and that he wished he had handled some aspects of the disclosure differently. The regret was real, which is to his credit, and it did not undo the damage, which is the hard part.
What this history asks of us
The Wasson story is an early case of a question the modern psychedelic field is still wrestling with. How do you engage with traditions that originated outside the West without distorting or destroying them in the process? The honest assessment is that Wasson's project, well-intentioned, carefully executed, and undeniably scholarly, nevertheless contributed to the disruption of an indigenous practice. The intentions and the outcomes did not line up, and pretending otherwise would be a disservice to everyone in the story.
Reading the Wasson record now, it is possible to admire his work and his sincerity while also recognizing the limits of his foresight. Both things can be true at once, and holding them together is the only honest way to tell it. The lessons of that history remain pointed for anyone working at the intersection of indigenous knowledge and outside research interest today, where the same temptations, to extract, to publish, to share what was never yours to share, are very much alive. The banker meant well. The town paid for it. That gap is the whole lesson.
