Wasson's article landed when things were ready for it. In the mid-20th century, scientists were already getting interested in psychoactive compounds. This was partly because mescaline had been isolated and synthesized from peyote decades earlier (Arthur Heffter isolated it in the late 1890s, and Ernst Späth synthesized it in 1919). After Wasson's trips, Albert Hofmann at Sandoz Pharmaceuticals in Switzerland isolated, identified (as psilocybin and psilocin), and synthesized the active compounds in Mexican mushrooms in the late 1950s. Having these pure, synthesized compounds meant that scientific research could happen in a standardized way, outside of traditional settings.
The first wave of Western psychedelic research (1950s-early 1960s) looked at a few different things. One early idea was to frame LSD and mescaline as "psychotomimetics"—drugs that caused temporary states mimicking psychosis, which might help us understand schizophrenia. For instance, researchers at Spring Grove State Hospital studied drug effects versus schizophrenic symptoms, though they quickly realized this model had limits. Some psychiatrists even took the drugs themselves, thinking they needed to understand what the patients were going through.
At the same time, research looked at the potential for therapy, focusing a lot on alcoholism. In Saskatchewan, Canada, psychiatrists Humphry Osmond and Abram Hoffer were pioneers in using high-dose LSD. Osmond suggested that creating a powerful, meaningful experience, maybe something like delirium tremens, could shock alcoholics into sobriety. Their studies reported pretty impressive 40-50% one-year sobriety rates. This work got a lot of attention; even Bill Wilson, co-founder of Alcoholics Anonymous, tried LSD and saw its potential. Other researchers explored psychedelics as additions to psychotherapy, believing they could lower defenses and help people process their emotions. Over a thousand scientific papers on LSD alone were published (1950-mid-1960s), covering various potential uses.
This scientific curiosity went hand-in-hand with philosophical and cultural movements. Aldous Huxley's 1954 book, The Doors of Perception, was huge. Based on his 1953 mescaline experience, which Humphry Osmond supervised, Huxley wrote compellingly about altered perception—colors and textures getting intense, the feeling of losing the self ("not-I"), time feeling endless, and a deep meaning in normal objects. Importantly, Huxley disagreed with the psychotomimetic model. He argued that mescaline temporarily disabled the brain's "reducing valve," letting you access a broader reality, or "Mind at Large." He connected his experience to mystical traditions, suggesting psychedelics could be tools for spiritual insight, artistic inspiration, and maybe even a less harmful way to escape the pressures of modern life. Osmond, corresponding with Huxley about the right words, coined "psychedelic" ("mind-manifesting"), purposely moving away from the pathological sounds of "psychotomimetic's."
The stage was set for psychedelics to move out of labs and into the general culture. Timothy Leary, a charismatic Harvard psychologist, read Wasson's LIFE article and tried psilocybin mushrooms in Mexico in 1960, which was a meaningful experience. Back at Harvard, he co-founded the Harvard Psilocybin Project with Richard Alpert (who later became Ram Dass). Their research first looked at therapeutic uses (like the Concord Prison Experiment to reduce re-offending) and religious experiences (the Marsh Chapel Experiment). They brought forward the influential "set and setting" idea—that your mindset and environment really shape your psychedelic experiences.

But, their methods started getting pretty controversial. Reports surfaced of researchers giving drugs to subjects, pressuring students to participate, administering substances to undergraduates against university rules, and generally lacking scientific care. The scandal that followed, which was covered by student newspapers, led to Leary and Alpert being fired from Harvard in 1963.

Free from school rules, Leary became a loud supporter of using psychedelics widely, urging people to "Turn on, tune in, drop out." His preaching and his relationship scandal at Harvard pushed LSD, especially, right into the heart of the 1960s counterculture. At the same time, author Ken Kesey (who first encountered LSD as a CIA-funded study volunteer) and his Merry Pranksters championed a more wild, populist approach. They traveled the US in their bus "Furthur," hosting "Acid Tests"—parties where LSD was given out for free (often high-quality Owsley Stanley acid) along with Grateful Dead music. This widespread, often unstructured use, linking psychedelics to anti-establishment rebellion and social upheaval, worried authorities and mainstream society.

The reaction was fast and decisive. A moral panic started, fueled by media stories about "bad trips," perceived dangers, and challenges to social norms. Starting in 1966, US states began banning LSD. In 1970, the US federal government passed the Controlled Substances Act (CSA), putting LSD, psilocybin, mescaline, and other psychedelics into Schedule I—the most restrictive group for drugs that have high potential for abuse and no accepted medical use. This was followed internationally by the 1971 UN Convention on Psychotropic Substances, which required similar global controls. These legal moves, driven mostly by the highly visible countercultural use rather than a careful look at earlier scientific research, effectively shut down proper psychedelic scientific study for decades. Lots of promising therapeutic avenues explored by Osmond and others were mostly abandoned, overshadowed by the cultural revolution and the resulting bans.
