The Harvard Psilocybin Controversy and Leary and Alpert’s Departure

The Harvard Psilocybin Controversy and Leary and Alpert’s Departure marked the point at which a dispute over research rules became a public scandal with consequences far beyond Harvard. An investigation by undergraduate reporter Andrew Weil exposed Richard Alpert’s provision of drugs to students, while press coverage made Timothy Leary a national figure. The university conflict ended their academic work there, but also helped move psychedelic research into a more contested and less institutional world.

Research Under Pressure

The controversy grew from an existing dispute over how psilocybin research was being conducted and who could take part. Harvard restricted access to the drugs to graduate students, and faculty members worried that participation was dividing the department into an insider group and those who did not participate. Richard Alpert defended the project as part of a tradition of inquiry into mystical experience; Leary accepted some restrictions. For a time, participants believed the matter had been settled.

The next morning, an undergraduate reporter for the Crimson, Robert Ellis Smith, published the dispute on the newspaper’s front page. A Boston Herald story followed with a more sensational, and less accurate, headline suggesting that 350 students had taken pills. The reporting transformed a faculty disagreement into a public controversy. Leary’s willingness to provide reporters with provocative remarks helped make him especially visible, while Harvard’s decision to place its supply of Sandoz psilocybin under Health Services control gave the conflict a concrete institutional focus.

The wider research network helps explain what was at stake. In the late 1950s, Al Hubbard had carried clinical experience and LSD supplies among researchers and treatment centers across North America, including work with Humphry Osmond and Abram Hoffer in Weyburn and sessions with researchers in Los Angeles. He later guided psychedelic journeys and trained others in Menlo Park, where Myron Stolaroff, Don Allen, and Willis Harman explored LSD’s possible value for healthy people as well as patients. This work depended on personal connections and the movement of knowledge between settings; Harvard’s attempt to regulate participation was therefore part of a broader argument over who could conduct research and under what conditions.

Weil’s Investigation

By spring 1963, Leary was already skipping classes and saying that he intended to leave Harvard when his contract ended. Alpert, by contrast, had a new appointment in the School of Education and planned to remain. The investigation that changed those plans began with Weil’s own interest in psychedelics. He had read Aldous Huxley’s The Doors of Perception in high school and approached Leary hoping to join the project. After Leary explained the graduate-student restriction, he told Weil where he might order mescaline by mail. Weil did so using university stationery and helped form an undergraduate mescaline group.

Weil later became troubled by reports that Alpert had given drugs to other undergraduates. Wanting to investigate, he developed leads on students who were said to have received them in violation of university rules. The story was difficult to publish directly: the students would not speak on the record, and the Crimson’s lawyers warned against printing potentially defamatory allegations about professors. They advised Weil to give the information to the university and report what the administration did. For that account, however, the newspaper needed a student willing to acknowledge receiving drugs.

Weil went to New York City to meet Harry Winston, the prominent jeweler and father of student Ronnie Winston. He offered to leave the son’s name out of the article if Ronnie admitted the allegation. Ronnie then confessed to the dean that he had received drugs from Alpert, describing the experience as educational. His statement supplied the public confirmation that Weil’s investigation had been unable to obtain from the other students.

Departure and Public Consequences

The resulting story brought the dispute to national attention. Alpert and Leary appear to have been the only Harvard professors fired in the twentieth century, although their formal circumstances differed: Harvard stopped paying Leary several months before his contract expired, while Alpert lost his position despite his plans to stay. Weil’s reporting also brought him a major assignment from Look magazine, extending the story’s reach. In describing the undergraduate mescaline group, however, he did not disclose that he had helped found it himself.

By the end of the year, Leary and Alpert had concluded that the drugs were too controversial to research within a university. They announced that they would continue under the International Federation for Internal Freedom, outside Harvard. They also protested what they saw as mounting restrictions on experimental research, connecting the controversy to the federal government’s growing authority over experimental drugs after the thalidomide tragedy. Their departure was therefore not simply a change of employer: it publicly dramatized a widening break between psychedelic research and the institutions expected to supervise it.

The dispute also had a personal aftermath. Weil later said he had felt badly about his reporting and sought to make amends to Leary and Alpert. Leary accepted his apology. Alpert, who later became Ram Dass, did not speak with Weil for years. After Alpert suffered a stroke in 1997, Weil traveled to Hawaii to seek forgiveness; Alpert eventually relented and came to regard his dismissal as a blessing, since it had set him on the path to becoming Ram Dass. Their later reconciliation recast the event without undoing its immediate consequences: the scandal ended their Harvard careers, but Alpert understood that departure as the beginning of a different life.

From Campus Dispute to Wider Conflict

The departures came amid a worsening public climate for psychedelic research. Reports of LSD use outside clinical settings, emergency-room visits, and acute psychological crises fed alarm among psychiatrists and in the media. In 1965, Bellevue Hospital admitted sixty-five people for what it classified as LSD-induced psychoses. Some people experienced serious psychotic breaks, while doctors unfamiliar with psychedelics sometimes mistook panic reactions for psychosis. Meanwhile, reports of risk circulated alongside selectively publicized or later-discredited claims, making balanced distinctions between supervised research and uncontrolled use harder to maintain.

That distinction was central to the controversy’s lasting significance. Leary and Alpert’s departure did not alone bring research to a halt, but their public conflict made it more difficult to defend the work as a bounded university activity separable from wider drug use. In April 1966, Sandoz withdrew LSD-25 from circulation, and in October the Food and Drug Administration ordered researchers across the United States to stop their work. The closures followed a wider collapse of psychedelic science; one program, at the Maryland Psychiatric Research Center at Spring Grove, continued. The sequence reveals how media attention, institutional discipline, public alarm, and federal controls converged, rather than reducing the shutdown to a single story or decision.

The departure also had a less immediate legacy. Later underground guides often traced their professional lineages back through Leary, alongside Stanislav Grof, Al Hubbard, and Leo Zeff. Research that resumed decades later drew in part on experience accumulated outside universities, and there was some movement between underground practitioners and academic teams. The Harvard conflict thus stands both as a rupture in formal research and as one of the events that pushed psychedelic practice into less visible channels, where its methods and knowledge continued to circulate.
