SRI’s Secret Psychedelic Experience Program

SRI’s Secret Psychedelic Experience Program was the concealed continuation of Al M Hubbard and Willis Harman’s effort to bring LSD experiences to influential people, even after the drug had become illegal. In 1968, Hubbard returned from semiretirement to the Stanford Research Institute as a part-time special investigative agent, ostensibly tasked with monitoring drug use in the student movement. The role’s official rationale was political surveillance; testimony about the work points instead to private sessions. That split between public assignment and hidden function made the program a striking instance of psychedelic research persisting under a government-facing cover story.

Return to SRI

By 1966, the International Foundation for Advanced Study had closed, and Harman had moved to SRI, a prestigious think tank affiliated with Stanford University that held contracts from several branches of the federal government, including the military. He directed the institute’s Educational Policy Research Center, whose mandate was to consider the future of education. LSD was illegal by then, but it remained in use among engineers and academics around Stanford. In 1968, Harman called Hubbard out of semiretirement and brought him into this institutional setting.

The circumstances differed sharply from Hubbard’s earlier work. He was now broke, and the openly organized foundation that had once connected psychedelic researchers was gone. Yet Harman’s renewed invitation suggests that the network and its aims had not simply disappeared with the organization. The work was being relocated into a setting with federal contracts and an educational-policy remit, where psychedelic activity could be described in terms of research into social change rather than openly presented as a continuation of clinical practice.

The investigative cover

Harman hired Hubbard part-time as a special investigative agent, ostensibly to keep tabs on drug use in the student movement. Harman’s employment letter described concern that some New Left student drug use might be a deliberate weapon aimed at political change, and proposed that Hubbard could access relevant information not ordinarily available. The wording gave the appointment a plausible intelligence-gathering purpose: Hubbard would assess the significance of drug use as it affected long-range educational policy.

The account does not establish whether Hubbard actually investigated illegal drug use on campus for SRI or another organization. It does, however, make clear that the stated assignment should not be mistaken for a full description of his work. The letter’s official framing sits beside evidence of a different, continuing objective, and the contrast is central to the episode: surveillance supplied an explanation for Hubbard’s presence, while the psychedelic project operated behind it.

Hubbard also used his extensive government connections to help keep SRI contracts flowing. The role was therefore not merely a cover for sessions; his contacts served the institute’s institutional interests as well. He returned to work in his familiar khaki security-guard uniform, with a gold badge, sidearm, and belt studded with bullets. The visible equipment made the appointment look like security work, reinforcing the impression created by his title and the employment letter.

The work behind the title

Harman’s stated mission with Hubbard was to provide LSD experiences to political and intellectual leaders around the world. According to Harman’s later account, and to a former SRI employee who confirmed it, Hubbard’s actual job was not security work: he ran special sessions. The evidence thus distinguishes the nominal assignment from the practical function without resolving every detail of how the sessions were arranged or who attended them. The secrecy is part of the record, not a license to fill in what it leaves unknown.

The program carried forward an approach that had already placed spiritual and cultural aims alongside medical research. In 1955, Hubbard had established the Commission for the Study of Creative Imagination and recruited researchers and other public figures to a network intended to take psychedelic work beyond medicine’s focus on illness. By 1957, he was saying that his regard for science as an end in itself was diminishing and that what he wanted lay beyond empirical manipulation. The later SRI mission to reach political and intellectual leaders belongs to that broader ambition: LSD was not only a possible therapeutic instrument, but a means of affecting people thought capable of shaping culture and institutions.

The program’s setting also sharpened the tension between official science and the experience it sought to produce. Psychedelic therapy already challenged psychiatric conventions because it relied on a high-dose session and on the combined influence of the drug, the therapist, and the surrounding conditions. At SRI, the contradiction took an institutional form: an ostensibly investigative position housed sessions whose purpose was to provide psychedelic experiences. The disguise did not erase the project’s continuity; it changed the terms under which that continuity could operate.

Documentary traces and significance

Peter Schwartz, an engineer who joined Harman at SRI in 1973, later recalled taking over Hubbard’s office when Hubbard was more or less retired. Above the desk hung a large photograph of Richard Nixon, inscribed to Hubbard in recognition of his years of service. Letters addressed to A. M. Hubbard had arrived from around the world; Schwartz remembered one from George Bush, then head of the Republican National Committee and later CIA director. These traces do not by themselves document the content of the sessions, but they convey the reach of Hubbard’s contacts and the institutional world surrounding his work.

Schwartz’s recollection also gives the secret program a small, concrete afterimage. One day, a round man with a gray crew cut arrived in a security-guard uniform, carrying a .38, to collect his mail. The figure matched the public-facing role, while the accounts of Harman and the former employee point to the concealed one. The mismatch is not incidental color: it captures how Hubbard’s security persona could coexist with a psychedelic mission that had become harder to acknowledge openly.

The episode shows that the end of legal psychedelic research did not immediately end the work or the networks behind it. Instead, at least some activity continued quietly, supported by personal ties and placed beneath an official rationale that made it appear to serve another purpose. The available evidence leaves the program’s full scope uncertain, but it establishes the essential reversal: at SRI, the man hired to investigate drug use was remembered by colleagues not as a security agent, but as the person who ran the sessions.
