Yes—with an important qualification. A 1977 Senate hearing documents CIA-linked, unwitting drug tests in safehouses in San Francisco and New York, including drugs administered in food or drink. A CIA-hosted excerpt from historian John Marks describes prostitutes luring men to a San Francisco apartment. The Senate record calls the sites safehouses, not brothels, and the evidence does not show that every visitor—or every person connected to MKULTRA—was given LSD.
What did the CIA do in the safehouses?
The Senate Select Committee’s 1977 hearing describes undercover officers associated with the Bureau of Narcotics selecting prospective subjects, administering drugs through food or drink at a safehouse, and watching the subjects from an adjoining room. The committee’s account places safehouse testing in both San Francisco and New York. It does not establish that every test took place in the same way or involved LSD.
The committee was explicit about the lack of safeguards in the tests it describes: “Prior consent was obviously not obtained from any of the subjects. There was also, obviously, no medical prescreening.” The statement appears in the hearing appendix’s account of unwitting testing.
Why are they called “brothels”?
The word comes from a later narrative account, not the Senate committee’s terminology. In an excerpt from The Search for the Manchurian Candidate hosted by the CIA’s Center for the Study of Intelligence, John Marks describes prostitutes enticing men to a San Francisco apartment where the drug testing took place. That supports the vivid shorthand in the headline, but “safehouse” is the term used in the official hearing record.

The CIA-hosted excerpt also reproduces the 1963 Inspector General’s assessment that “Possible sickness and attendant economic loss are inherent contingent effects of the testing.” The sentence is presented in Marks’s account as language from the Inspector General’s report; the excerpt is not the original report.
What was Operation Midnight Climax?
Operation Midnight Climax is the name commonly associated with the CIA’s San Francisco safehouse activity: undercover approaches, covert drug administration, and observation of unwitting people. The hearing’s account is useful for establishing the broader safehouse testing and its methods; Marks’s excerpt supplies the specific detail about prostitutes drawing men to an apartment. Those sources should not be conflated into a claim that every safehouse or test operated identically.
How did the safehouse tests relate to MKULTRA?
The safehouse testing was part of a much wider CIA program, not a measure of its total scale. In its 1977 account of recovered records, the Senate committee discusses 149 MKULTRA subprojects and names 80 institutions where work was carried out or with which associated researchers were affiliated. Neither figure counts safehouses, people dosed, or victims of Operation Midnight Climax.
MKULTRA covered a broader range of work than the unwitting U.S. safehouse tests. Treating the two as interchangeable obscures both the scale of the larger program and the narrower scope of the specific activity described in the hearing.
Rank #3
When did the unwitting U.S. testing end?
The hearing’s appendix says an Inspector General staff member learned of the project during a 1963 review. The unwitting U.S. testing was then suspended, and the surreptitious-administration activity described in the appendix was terminated in 1963.
That date does not mark the end of MKULTRA as a whole. The committee separately reports that the broader program’s funding and activities declined over later budget years before MKULTRA was terminated in the late 1960s.
