Searching online to see if mushrooms sprouting in his yard were the hallucinogenic variety, he had come across a pioneering medical trial at Imperial College London. Listening to music and surrounded by candles and flowers in the decorated clinical room, Michael anxiously waited for the drug to kick in. After 50 minutes, he saw bright lights leading into the distance and embarked on a five-hour journey into his own mind, where he would re-live a range of childhood memories and confront his grief.
For the next three months, his depressive symptoms waned. He felt upbeat and accepting, enjoying pastimes he had come to feel apathetic about, such as walking through the Yorkshire countryside and taking photographs of nature. I was supremely confident — more like I was when I was younger, before the depression started and got to its worst.
The trial, finished in , was the first modern study to target treatment-resistant depression with psilocybin , a psychedelic drug naturally occurring in around species of mushroom. To varying degrees, Michael and all 18 other participants saw their symptoms reduce a week after two treatments, including a high, 25mg dose. They had suffered from depression for an average of 18 years and all had tried other treatments.
The team has now treated about a third of the 60 patients and say that early results are promising for psilocybin. Psilocybin mushrooms have been part of religious rituals for thousands of years. In , Albert Hoffman, a Swiss chemist working for the pharmaceutical company Sandoz, isolated psilocybin from the mushroom. Fifteen years earlier, he had accidentally ingested LSD, left work feeling dizzy, and experienced its psychedelic effects when he got home.
During the s, Sandoz sold psilocybin and LSD for research in medical trials, but the substances were soon outlawed after they became associated with the 60s counterculture. The race to invent and patent faster ways to mass-produce pharmaceutical grade psilocybin is on.
The movement to decriminalize psychedelics, in contrast, is grounded in political critiques of the health care system, the pharmaceutical industry, and drug policy, and the ills of industrial modernity more broadly—settler colonialism, capitalist exploitation, ecological destruction, and so on.
Supporters stress the accessibility of foraged and homegrown psychedelics and their traditional consumption in precolonial cultures. And it is true, as naturally occurring organisms, these psilocybin production processes—i. Such rhetoric often mobilizes a familiar conflation of naturalness, indigeneity, and ecological redemption while attempting to align present-day consumption practices with premodern ones.
The actual history and culture of psilocybin mushrooms in the United States is one that departs from and complicates this popular discourse of naturalness, and contemporary techniques for growing mushrooms, now being taught widely in this wake of decriminalization, are products of that history. Since the s, driven by a desire to cultivate and forage psilocybin-active mushrooms, psychedelic enthusiasts developed a unique technoscientific practice, fostering several not-quite-wild, not-quite-domesticated species across the American landscape.
Their practices were shaped by ecological values and a collaborative multispecies ethos that promiscuously adapted modern lab techniques. The history and present of psilocybin mushrooms in North America is a model of Latourian nature-culture: it undermines the binary on which constructions of naturalness rely. It also provides an opening for popular iterations of the nature-culture concept and the co-creation of human and nonhuman life.
Psilocybin mushrooms were first cultivated indoors beginning in the mids.
