MKUltra

Origin of the project During the early 1940s, Nazi scientists working in the concentration camps of Auschwitz and Dachau during World War II conducted interrogation experiments on human subjects. Substances such as barbiturates, morphine derivatives, and hallucinogens such as mescaline were employed in experiments conducted on Polish, Russian, Ukrainian, Jewish, and other prisoners of war. American historian Stephen Kinzer said that the CIA project was a continuation of these earlier Nazi experiments, as evidenced by MKUltra's use of mescaline on unwitting subjects, replicating previous Nazi experiments conducted at Dachau. Numerous Nazi scientists would be employed by the United States government after the war as part of Operation Paperclip, with some figures such as Kurt Blome becoming involved in MKUltra. American interest in drug-related interrogation experiments began in 1943, when the Office of Strategic Services began developing a "truth drug" that would produce "uninhibited truthfulness" in an interrogated person. In 1947, the United States Navy initiated Project CHATTER, an interrogation program which saw the first testing of LSD on human subjects. In 1950, the Central Intelligence Agency under the direction of General Walter Bedell Smith initiated a series of interrogation projects involving human subjects, beginning with the launch of Project Bluebird, officially renamed Project Artichoke on August 20, 1951. Directed and overseen by Brigadier General Paul F. Gaynor, the objective of Artichoke was to determine whether an individual could be made to involuntarily perform an act of attempted assassination. Morphine, mescaline and LSD were all administered to unknowing CIA agents in an attempt to produce amnesia in the subjects. In addition, Project Artichoke aimed to employ certain viruses such as dengue fever as potential incapacitating agents. Aims and leadership approved of an MKUltra sub-project on LSD in this June 9, 1953, letter. The project was headed by Sidney Gottlieb but began on the order of CIA director Allen Dulles on April 13, 1953. Its aim was to develop mind-controlling drugs for use against the Soviet bloc in response to alleged Soviet, Chinese, and North Korean use of mind control techniques on U.S. prisoners of war during the Korean War. The CIA wanted to use similar methods on their own captives, and was interested in manipulating foreign leaders with such techniques, devising several schemes to drug Fidel Castro. It often conducted experiments without the subjects' knowledge or consent. In some cases, academic researchers were funded through grants from CIA front organizations but were unaware that the CIA was using their work for these purposes. The project attempted to produce a perfect truth serum for interrogating suspected Soviet spies during the Cold War and to explore other possibilities of mind control. Subproject 54 was the Navy's top-secret "Perfect Concussion" program, which was supposed to use sub-aural frequency blasts to erase memory; the program was never carried out. Most MKUltra records were destroyed in 1973 by order of CIA director Richard Helms, so it has been difficult for investigators to gain a complete understanding of the more than 150 funded research subprojects sponsored by MKUltra and related CIA programs. The project began during a period of what English journalist Rupert Cornwell described as "paranoia" at the CIA, when the U.S. had lost its nuclear monopoly and fear of communism was at its height. CIA counter-intelligence chief James Jesus Angleton believed that a mole had penetrated the organization at the highest levels. Some historians assert that one goal of MKUltra and related CIA projects was to create a Manchurian Candidate–style subject. American historian Alfred W. McCoy has claimed that the CIA attempted to focus media attention on these sorts of "ridiculous" programs so that the public would not look at the research's primary goal, which was effective methods of interrogation. Other related projects In 1964, MKSEARCH was the name given to the continuation of the MKULTRA program. The MKSEARCH program was divided into two projects dubbed MKOFTEN and MKCHICKWIT. Funding for MKSEARCH commenced in 1965, and ended in 1971. The CIA was interested in bird migration patterns for chemical and biological warfare (CBW) research; subproject 139 designated "Bird Disease Studies" at Pennsylvania State University. MKOFTEN was to deal with testing and toxicological transmissivity and behavioral effects of drugs in animals and, ultimately, humans. MKCHICKWIT was concerned with acquiring information on new drug developments in Europe and Asia, and with acquiring samples. This subproject aimed to explore innovative techniques for manipulating and controlling human behavior, particularly through the methods of "psychic driving" and "depatterning". Psychic driving involved subjecting patients to continuous playback of recorded messages, often with themes of self-improvement or identity reinforcement, while they were under the influence of powerful psychoactive substances such as LSD or barbiturates. ==Experiments on Americans==

CIA documents suggest that they investigated "chemical, biological, and radiological" methods of mind control as part of MKUltra. They spent an estimated $10 million or more, roughly $87.5 million adjusted for inflation. During a hearing by the Senate Health Subcommittee, a testimony by the deputy director of the CIA stated that over 30 institutions and universities were involved in the experimentation program of testing drugs on unknowing citizens "at all social levels, high and low, native Americans and foreign." Several of these tests involved the issuing of LSD to unaware subjects in social situations. Files discovered in 1977 containing 700 pages of new information showed that experiments had continued until Gottlieb ordered the program halted on July 10, 1972. LSD In 1938, LSD was isolated by Albert Hofmann at the Sandoz Laboratories in Basel, Switzerland. The early directors of MKUltra became aware of the existence of LSD and sought to use it for "mind-control". In the early 1950s, MKUltra director Sidney Gottlieb arranged for the CIA to buy the entire supply of LSD for $240,000, which in 2024, would be $4,227,079. This LSD supply gave Gottlieb the ability to fulfill his experiment by spreading LSD to prisons, hospitals, institutions, clinics, and foundations in order to see how citizens would react to the drug without knowing exactly what was happening to them. Early CIA efforts focused on LSD-25, which later came to dominate many of MKUltra's programs. The CIA wanted to know if they could make Soviet spies defect against their will and whether the Soviets could do the same to the CIA's own operatives. Documents obtained from the CIA by John D. Marks under Freedom of Information in 1976 showed that, in 1953, the CIA considered purchasing 10 kilograms of LSD, enough for 100 million doses. The proposed purchase aimed to stop other countries from controlling the supply. The documents showed that the CIA purchased some quantities of LSD from Sandoz Laboratories in Switzerland. Once Project MKUltra started, in April 1953, experiments included administering LSD to mental patients, prisoners, drug addicts, and prostitutes – "people who could not fight back", as one agency officer put it. In one case, they administered LSD to a mental patient in Kentucky for 174 days. Military personnel who received the mind-altering drugs were also threatened with court-martial if they told anyone about the experiments. LSD and other drugs were often administered without the subject's knowledge or informed consent, a violation of the Nuremberg Code the U.S. had agreed to follow after World War II. Many veterans who were subjected to experimentation later sought legal and monetary reparations. In other experiments where people were given LSD without their knowledge, they were interrogated under bright lights with doctors in the background taking notes. They told subjects they would extend their "trips" if they refused to reveal their secrets. The people subjected to these interrogations were CIA employees, U.S. military personnel, and agents suspected of working for the Soviet Bloc during the Cold War. Long-term debilitation and several deaths resulted from this. At the invitation of Stanford psychology graduate student Vik Lovell, an acquaintance of Allen Ginsberg, Ken Kesey volunteered to take part in what turned out to be a CIA-financed study under the aegis of MKUltra, at the Menlo Park Veterans' Hospital where he worked as a night aide. The project studied the effects of hallucinogens and other psychoactive drugs, particularly LSD, psilocybin, mescaline, cocaine, AMT, and DMT on people. The Office of Security used LSD in interrogations, but Sidney Gottlieb, the chemist who directed MKUltra, had other ideas: he thought it could be used in covert operations. Since its effects were temporary, he believed it could be given to high-ranking officials and in this way affect the course of important meetings, speeches, etc. Since he realized there was a difference in testing the drug in a laboratory and using it in clandestine operations, he initiated a series of experiments where LSD was given to people in "normal" settings without warning. At first, everyone in Technical Services tried it; a typical experiment involved two people in a room where they observed each other for hours and took notes. As the experimentation progressed, a point arrived where outsiders were drugged with no explanation whatsoever and surprise acid trips became something of an occupational hazard among CIA operatives. Adverse reactions often occurred, such as an operative who received the drug in his morning coffee, became psychotic and ran across Washington, D.C., seeing a monster in every car passing him. The experiments continued even after Frank Olson, an army chemist who had never taken LSD, was covertly dosed by his CIA supervisor and nine days later plunged to his death from the window of a 13th-story New York City hotel room, supposedly as a result of deep depression induced by the drug. According to Stephen Kinzer, Olson had approached his superiors some time earlier, doubting the morality of the project, and asked to resign from the CIA. Some subjects' participation was consensual, and in these cases they appeared to be singled out for even more extreme experiments. In one case, seven drug-addicted African-American participants at the National Institute of Mental Health Addiction Research Center in Kentucky were given LSD for 77 consecutive days. MKUltra's researchers later dismissed LSD as too unpredictable in its results. They gave up on the notion that LSD was "the secret that was going to unlock the universe", but it still had a place in the cloak-and-dagger arsenal. However, by 1962, the CIA and the army developed a series of super-hallucinogens such as the highly touted BZ, which was thought to hold greater promise as a mind control weapon. This resulted in the withdrawal of support by many academics and private researchers, and LSD research became less of a priority altogether. The barbiturates were released into the person first, and as soon as the person began to fall asleep, the amphetamines were released. Other experiments involved heroin, morphine, temazepam (used under code name MKSEARCH), mescaline, psilocybin, scopolamine, alcohol and sodium pentothal. A 1955 MKUltra document details research objectives to identify drugs that could be used as cognitive enhancers, disease mimetics, euphoriants “without letdown,” and agents to diminish ambition, among other uses. Hypnosis Declassified MKUltra documents indicate they studied hypnosis in the early 1950s. Experimental goals included creating "hypnotically induced anxieties", "hypnotically increasing ability to learn and recall complex written matter", studying hypnosis and polygraph examinations, "hypnotically increasing ability to observe and recall complex arrangements of physical objects", and studying "relationship of personality to susceptibility to hypnosis". They conducted experiments with drug-induced hypnosis and with anterograde and retrograde amnesia while under the influence of such drugs. ==Experiments on Canadians==

The CIA exported experiments to Canada when they recruited Scottish psychiatrist Donald Ewen Cameron, creator of the "psychic driving" concept, which the CIA found interesting. Cameron had been hoping to correct schizophrenia by erasing existing memories and reprogramming the psyche. He commuted from Albany, New York to Montreal every week to work at the Allan Memorial Institute of McGill University, and was paid $69,000 from 1957 to 1964 (US$766,936 in 2024, adjusted for inflation) to carry out MKUltra experiments there. The Montreal experiments research funds were sent to Cameron by a CIA front organization, the Society for the Investigation of Human Ecology, and as shown in internal CIA documents, Cameron did not know the money came from the CIA. In addition to LSD, Cameron also experimented with various paralytic drugs as well as electroconvulsive therapy at thirty to forty times the normal power. His "driving" experiments consisted of putting subjects into drug-induced comas for weeks at a time (up to three months in one case) while playing tape loops of noise or simple repetitive statements. His experiments were often carried out on patients who entered the institute for common problems such as anxiety disorders and postpartum depression, many of whom suffered permanent effects from his actions. During this era, Cameron became known worldwide as the first chairman of the World Psychiatric Association as well as president of both the American Psychiatric Association and the Canadian Psychiatric Association. Cameron was also a member of the Nuremberg medical tribunal in 1946–1947. Although Sargant acted as a consultant for MI5, no evidence has emerged that his work with deep sleep treatment at St Thomas' hospital had any links with intelligence services. In the 1980s, several of Cameron's former patients sued the CIA for damages, which the Canadian news program The Fifth Estate documented. Their experiences and lawsuit were adapted in the 1998 television miniseries The Sleep Room. Naomi Klein argues in her book The Shock Doctrine that Cameron's research and his contribution to the MKUltra project was not about mind control and brainwashing, but about designing "a scientifically based system for extracting information from 'resistant sources'. In other words, torture." Alfred W. McCoy writes, "Stripped of its bizarre excesses, Dr. Cameron's experiments, building upon Donald O. Hebb's earlier breakthrough, laid the scientific foundation for the CIA's two-stage psychological torture method", ==Secret detention camps==

In areas under American control in the early 1950s in Europe and East Asia, mostly Japan, West Germany and the Philippines, the CIA created secret detention centers (black sites) so that the U.S. could avoid criminal prosecution. The CIA captured people suspected of being enemy agents and other people it deemed "expendable" to undergo various types of torture and human experimentation. The prisoners were interrogated while being administered psychoactive drugs, electroshocked and subjected to extremes of temperature, sensory isolation and the like to develop a better understanding of how to destroy and to control human minds. ==Project Bluebird==

In October 1950, during the Korean War, North Korean POWs under U.S. custody were reportedly subjected to experiments under Project Bluebird, a precursor to MK-ULTRA. According to declassified documents released by the National Security Archive in 2024-2025, these experiments involved the use of various drugs and advanced interrogation techniques, with the stated aim of "controlling an individual to the point where he will do our bidding against his will and even against such fundamental laws of nature as self-preservation". ==Revelation==

In 1973, amid a government-wide panic caused by the Watergate scandal, CIA Director Richard Helms ordered all MKUltra files destroyed. Pursuant to this order, most CIA documents regarding the project were destroyed, making a full investigation of MKUltra impossible. A cache of some 20,000 documents survived Helms's purge, as they had been incorrectly stored in a financial records building and were discovered following a FOIA request in 1977. These documents were fully investigated during the Senate Hearings of 1977. That report prompted investigations by the United States Congress, in the form of the Church Committee, and by a commission known as the Rockefeller Commission that looked into the illegal domestic activities of the CIA, the FBI and intelligence-related agencies of the military. In the summer of 1975, congressional Church Committee reports and the presidential Rockefeller Commission report revealed to the public for the first time that the CIA and the Department of Defense had conducted experiments on both unwitting and cognizant human subjects as part of an extensive program to find out how to influence and control human behavior through the use of psychoactive drugs such as LSD and mescaline and other chemical, biological, and psychological means. They also revealed that at least one subject, Frank Olson, had died after administration of LSD. Much of what the Church Committee and the Rockefeller Commission learned about MKUltra was contained in a report, prepared by the Inspector General's office in 1963, that had survived the destruction of records ordered in 1973. However, it contained little detail. Sidney Gottlieb, who had retired from the CIA two years previously and had headed MKUltra, was interviewed by the committee but claimed to have very little recollection of the activities of MKUltra. that had survived the 1973 destruction orders because they had been incorrectly stored at a records center not usually used for such documents. In Canada, the issue took much longer to surface, becoming widely known in 1984 on a CBC news show, The Fifth Estate. It was learned that not only had the CIA funded Cameron's efforts, but also that the Canadian government was aware of this, and had later provided another $500,000 in funding to continue the experiments. This revelation largely derailed efforts by the victims to sue the CIA as their U.S. counterparts had, and the Canadian government eventually settled out of court for $100,000 to each of the 127 victims. Cameron died on September 8, 1967, after suffering a heart attack while he and his son were mountain climbing. None of Cameron's personal records of his involvement with MKUltra survived because his family destroyed them after his death. A 1986 report found that Canadian government officials were not fully aware of Cameron's experiments. 1994 U.S. General Accounting Office report The U.S. General Accounting Office issued a report on September 28, 1994, which stated that between 1940 and 1974, the Department of Defense and other national security agencies tested hazardous substances and radiation on hundreds of thousands of human subjects. Based on this report and other sources, the Senate Committee on Veterans' Affairs concluded: CIA vs Sims In CIA v. Sims (1985), the U.S. Supreme Court endorsed the mosaic effect to justify broad judicial deference under FOIA Exemption 3, allowing the CIA to withhold seemingly innocuous details about MKUltra on the grounds that aggregated disclosures could expose intelligence sources. This rationale has since granted the agency near-total immunity from FOIA, and has been broadly applied by lower courts. == Death of Frank Olson ==

Several known deaths have been associated with Project MKUltra, most notably that of Frank Olson. By 1951, Olson was a United States Army biochemist and biological weapons researcher. In 1953, a few days before his death, Frank Olson quit his position as acting chief of the Special Operations Division at Detrick, Maryland (later Fort Detrick) because of a severe moral crisis concerning the nature of his biological weapons research. Among Olson's concerns were: • the development of assassination materials used by the CIA • the CIA's use of biological warfare materials in covert operations • experimentation with biological weapons in populated areas • collaboration with former Nazi scientists under Operation Paperclip • LSD mind control research • the use of psychoactive drugs during "terminal" interrogations under a program code-named Project Artichoke In November 1953, Olson was given LSD without his knowledge or consent as part of a CIA experiment, and died after falling from a 13th-story window a week later. A CIA doctor assigned to monitor Olson claimed to have been asleep in another bed in a New York City hotel room when Olson fell to his death. In 1953, Olson's death was described as a suicide that had occurred during a severe psychotic episode. The CIA's own internal investigation concluded that the head of MKUltra, CIA chemist Sidney Gottlieb, had conducted the LSD experiment with Olson's prior knowledge, although neither Olson nor the other men taking part in the experiment were informed as to the exact nature of the drug until some 20 minutes after its ingestion. The report further suggested that Gottlieb was nonetheless due a reprimand, as he had failed to take into account Olson's already-diagnosed suicidal tendencies, which might have been exacerbated by the LSD. In 1994, Olson's body was exhumed and cranial injuries indicated that Olson had been knocked unconscious before he exited the window. This means the forensic evidence conflicted with the former official version of events by the CIA. The medical examiner termed Olson's death a "homicide". Since 2001 (or earlier), the Olson family disputes the official version of events. They maintain that Frank Olson was murdered because, especially in the aftermath of his LSD experience, he had become a security risk who might divulge state secrets associated with highly classified CIA programs, about many of which he had direct personal knowledge. A 2010 book alleged: • that the 1951 Pont-Saint-Esprit mass poisoning was part of MKDELTA • that Olson was involved in that event • that he was eventually murdered by the CIA On November 28, 2012, the Olson family filed suit against the U.S. federal government for the wrongful death of Frank Olson. In 2013 (July) the case was dismissed, due in part to the 1976 settlement between the family and government. In the decision dismissing the suit, U.S. District Judge James Boasberg wrote, While the court must limit its analysis to the four corners of the complaint, the skeptical reader may wish to know that the public record supports many of the allegations [in the family's suit], farfetched as they may sound. ==Legal issues involving informed consent==

The revelations about the CIA and the Army prompted a number of subjects or their survivors to file lawsuits against the federal government for conducting experiments without informed consent. Although the government aggressively, and sometimes successfully, sought to avoid legal liability, several plaintiffs did receive compensation through court order, out-of-court settlement, or acts of Congress. Frank Olson's family received $750,000 by a special act of Congress, and both President Ford and CIA director William Colby met with Olson's family to apologize publicly. Previously, the CIA and the Army had actively and successfully sought to withhold incriminating information, even as they secretly provided compensation to the families. One subject of army drug experimentation, James Stanley, an army sergeant, brought an important, albeit unsuccessful, suit. The government argued that Stanley was barred from suing under the Feres doctrine. In 1987, the Supreme Court affirmed this defense in a 5–4 decision that dismissed Stanley's case: United States v. Stanley. The majority argued that "a test for liability that depends on the extent to which particular suits would call into question military discipline and decision making would itself require judicial inquiry into, and hence intrusion upon, military matters." In dissent, Justice William Brennan argued that the need to preserve military discipline should not protect the government from liability and punishment for serious violations of constitutional rights: Justice Sandra Day O'Connor, writing a separate dissent, stated: In another lawsuit, Wayne Ritchie, a former United States Marshal, after hearing about the project's existence in 1990, alleged the CIA laced his food or drink with LSD at a 1957 Christmas party, which resulted in his attempting to commit a robbery at a bar and his subsequent arrest. While the government admitted it was, at that time, drugging people without their consent and that Ritchie's behavior was typical of someone on LSD, U.S. District Judge Marilyn Hall Patel found Ritchie could not prove he was one of MKUltra's victims or that LSD caused his robbery attempt, and dismissed the case in 2005. ==Notable people==

Documented experimenters Confirmed experimenters: • Harold Alexander Abramson • Donald Ewen Cameron • Sidney Gottlieb • Harris Isbell Alleged experimenters: • Jim Jones • Charlie Siragusa Documented subjects Confirmed subjects: • Allen Ginsberg first took LSD in an experiment on Stanford University's campus where he could listen to records of his choice (he chose a Gertrude Stein reading, a Tibetan mandala mantra, and Richard Wagner). He said the experience resulted in "a slight paranoia that hung on all my acid experiences through the mid-1960s until I learned from meditation how to disperse that." He became an outspoken advocate for psychedelics in the 1960s and, after hearing suspicions that the experiment was CIA-funded, wrote, "Am I, Allen Ginsberg, the product of one of the CIA's lamentable, ill-advised, or triumphantly successful experiments in mind control?" • Ken Kesey, author of ''One Flew Over the Cuckoo's Nest'', is said to have volunteered for MKUltra experiments involving LSD and other psychedelic drugs at the Veterans Administration Hospital in Menlo Park while he was a student at nearby Stanford University. Kesey's experiences while under the influence of LSD inspired him to promote the drug outside the context of the MKUltra experiments, which influenced the early development of hippie culture. • Harold Blauer was an American tennis player who died from injections of 3,4-Methylenedioxyamphetamine in the New York State Psychiatric Institute, which he had voluntarily checked into due to his depression following a divorce. • Robert Hunter was an American lyricist, singer-songwriter, translator, and poet, best known for his association with Jerry Garcia and the Grateful Dead. Along with Ken Kesey, Hunter was said to be an early volunteer MKUltra test subject at Stanford University. Stanford test subjects were paid to take LSD, psilocybin, and mescaline, then report on their experiences. These experiences were creatively formative for Hunter: Alleged subjects: • James "Whitey" Bulger, an organized crime boss, alleged he had been subjected to weekly injections of LSD and subsequent testing while in prison in Atlanta in 1957. • Ted Kaczynski, an American domestic terrorist known as the Unabomber, was said to be a subject of a voluntary psychological study alleged by some sources to have been a part of MKUltra. As a sophomore at Harvard, Kaczynski participated in a study described by author Alston Chase as a "purposely brutalizing psychological experiment", led by Harvard psychologist Henry Murray. In total, Kaczynski spent 200 hours as part of the study. • Sirhan Sirhan's attorney, Lawrence Teeter, believed that Sirhan was "operating under MKUltra mind control techniques" when he assassinated Robert F. Kennedy. • Charles Manson has been tied to MKUltra by author Tom O'Neil, beginning with his time in prison, when Manson took part in drug-induced psychological experiments run by the federal government. Such experiments hypothetically could have been continued through his ongoing connection to the Haight Ashbury Free Clinic in San Francisco once out of prison in 1967. ==In popular culture==

MKUltra plays a part in many conspiracy theories due to its nature and to the destruction of most records concerning it. This has also led to the idea that the human experiments performed by the CIA are ongoing in the present day. • The sixth and final volume of John Burdett's Bangkok detective novel series (2003-2015), The Bangkok Asset, features MKUltra as a major theme. The novel expands the impacts of the program to ultimately include the creation of super soldier-spies with "transhuman abilities". • The 2009 film The Killing Room is a thriller based on the real life MKUltra top secret government psychological program in which various volunteer test subjects are put in a tense situation. • The BYU television series Granite Flats (2013-2015) was based on the CIA's implementation of an MKUltra experiment on one of the series's characters, Lt. Frank Quincy (Scott Christopher), in an attempt to transform him into a conscienceless assassin. • Screenrant writer Kara Hedash wrote that plot points in the Netflix series Stranger Things (2016-2025) were inspired by MKUltra experiments. • Wormwood is a 2017 American six-part docudrama miniseries directed by Errol Morris and released on Netflix. The series is based on the life of the scientist Frank Olson and his involvement in Project MKUltra. • Will Wood's 2020 album The Normal Album features a song titled "BlackBoxWarrior – OKULTRA", which describes the experience of an MKUltra victim among other themes. ==See also==
