Central Intelligence Agency
How to Change Your MindThe Central Intelligence Agency’s most consequential role in the book’s history of psychedelics is its covert MK-Ultra program, an effort to turn LSD and related compounds into instruments of control. Beginning in 1953, the program explored mind manipulation, interrogation, biological warfare, and political disruption. Its ambition to control what a drug might make people do stood in stark contrast to researchers and guides who treated the psychedelic experience as something to be carefully supported, not weaponized. The contrast is not merely a disagreement over technique: it marks a struggle over whether these substances belong to military intelligence, psychiatric medicine, or a spiritual practice beyond either institution’s easy control.
MK-Ultra and the Search for Control
MK-Ultra’s objectives ranged widely. The Central Intelligence Agency considered whether LSD could act as a nonlethal weapon if introduced into an adversary’s water supply, serve as a truth serum or interrogation aid, enable mind control, or embarrass unfriendly foreign leaders by making them behave foolishly in public. At different points, the research program involved forty-four universities and colleges. The varied settings did not change the underlying question: whether covert administration of a psychedelic could reliably alter an individual’s behavior for the agency’s purposes.
The program’s ambitions were not matched by demonstrated success. The proposed schemes did not pan out, at least as far as the available record shows. The book places this work within a psychotomimetic model, which understood psychedelic effects chiefly through their resemblance to mental illness. That framework persisted in the agency’s research even as other investigators explored different interpretations and uses. Where therapeutic researchers increasingly emphasized the participant’s expectations and surroundings, MK-Ultra treated the drug as a possible lever for producing a desired effect on another person.
Secret Dosing and Human Consequences
The Central Intelligence Agency dosed its own employees as well as civilians who had not agreed to take LSD. A notorious case involved Frank Olson, an Army biological-warfare specialist whom the agency later admitted it had secretly dosed in 1953. A few days afterward, Olson supposedly fell or jumped to his death from the thirteenth floor of the Statler Hotel in New York. The account remains contested: some believed he had been pushed, and that the agency’s admission about the LSD was a cover for a more serious crime. The episode therefore stands both as evidence of nonconsensual experimentation and as an unresolved question about the limits of what the agency disclosed.
The program’s secrecy also damaged the historical record. In 1973, most of MK-Ultra’s documents were destroyed on the orders of Central Intelligence Agency director Richard Helms. The public learned of the program during the 1975 Church Committee hearings on the agency; further hearings followed in 1977. Because so many records had disappeared, the later investigations could reveal the program’s reach and aims without fully restoring what had happened in every experiment. The archival gap is part of the story: secrecy did not end when the experiments stopped, but continued to shape what could be known about them.
Hubbard, Researchers, and a Possible Connection
The agency’s research intersected with the wider North American psychedelic network through people who moved among research groups, treatment centers, and sources of LSD. By the late 1950s, Al Hubbard was supplying Sandoz LSD and therapeutic advice to researchers across the continent, including Humphry Osmond and Abram Hoffer in Weyburn and investigators in Los Angeles. He also established links with research centers that included Menlo Park. The breadth of his network prompted a question the book leaves unsettled: whether Hubbard was only circulating information and clinical knowledge, or also collecting material for the Central Intelligence Agency.
There is no definitive answer in the account. Some people who knew Hubbard considered a connection plausible; others pointed out that he criticized the agency’s use of LSD as a weapon. His access to researchers and drug supplies might make him look like a potential intermediary, but access is not proof of espionage. The unresolved possibility illuminates the mistrust surrounding psychedelic research at the time: the same network that carried therapeutic methods and LSD between investigators could also invite suspicion that knowledge was being gathered for covert purposes.
The relationship between agency research and psychedelic culture was not limited to speculation about intermediaries. James Moore, who introduced himself to R. Gordon Wasson as a pharmaceutical-company chemist, was in fact a Central Intelligence Agency agent seeking psilocybin for MK-Ultra. On another strand of the story, Ken Kesey took part in an agency-funded LSD experiment and then, with the Merry Pranksters, organized Acid Tests attended by thousands of young people in the Bay Area. In the book’s account, the agency had turned on the wrong person: an experiment intended as part of secret research became entangled with a public cultural movement whose scale and direction could not be contained by the original purpose.
The Agency’s Model and the Therapeutic Divide
The Central Intelligence Agency’s drug research belongs to a broader conflict over how psychedelics should be understood and used. In the mid-1950s, Al Hubbard, Humphry Osmond, and Aldous Huxley advanced a therapeutic model built around a high-dose experience and its surrounding conditions. That approach challenged psychiatric convention by treating the session as potentially transformative, rather than as a drug-induced imitation of illness or simply an adjunct to talk therapy. The agency’s interest in mind control and covert manipulation lay at the opposite pole: it sought to make the drug useful to an operator, while therapeutic practice sought to create conditions in which a participant might undergo a meaningful experience.
The difference also exposes a difficulty in separating pharmacology from context. In later clinical research, participants and guides could often tell whether psilocybin or a placebo had been administered, complicating efforts to blind a trial. Researchers also had to reckon with the influence of expectations, guides, and surroundings. The agency’s objectives assumed that a compound might be isolated as an instrument of control; the therapeutic account insists that its effects cannot be cleanly separated from the experience built around it. The two approaches therefore reveal opposing claims about what a psychedelic is: a covert tool for altering behavior, or a drug whose effects depend in consequential ways on the human setting in which it is taken.
Legacy and Limits of the Record
MK-Ultra’s legacy in the book is not a successful technology of control. Its intended schemes failed, its experiments included involuntary dosing, and the destruction of records left the extent and circumstances of its work only partially recoverable. Yet the program mattered beyond its own stated aims. Kesey’s participation preceded his organization of the Acid Tests, giving the account a sharp reversal: research designed to explore control helped place LSD in a setting of collective cultural experimentation instead.
The Central Intelligence Agency consequently occupies two connected but distinct places in this history. It was an institution that pursued psychedelic drugs for covert military and political ends, and its secrecy and human experimentation became a source of enduring uncertainty. It was also an unintended participant in a larger story in which substances moved across institutional boundaries and acquired meanings the agency could not dictate. The surviving account does not resolve every question about who knew what, or what every experiment produced. It does make clear that the agency’s attempt to master the drug’s effects became part of a history defined by contested control, incomplete evidence, and uses that escaped its original design.
