Project MKSEARCH

Central Intelligence Agency research program launched in 1965 as the operational successor to MK-Ultra, focusing on development and deployment of chemical and biological agents for intelligence operations. Unlike its predecessor's broad experimental scope, MKSEARCH concentrated on practical applications of mind-altering substances, incapacitating agents, and behavioral control techniques for field use by CIA operatives and allied intelligence services.

The program operated through a network of front organizations, university researchers, and pharmaceutical companies, conducting research on LSD, BZ (a potent hallucinogen), various drugs for interrogation enhancement, and techniques for covert administration of psychoactive substances. MKSEARCH also investigated methods for inducing amnesia, creating false memories, and developing untraceable assassination techniques using biological and chemical agents. Much of the research focused on practical operational applications rather than basic scientific inquiry.

MKSEARCH activities were terminated in 1972 following internal CIA reviews of ethics violations and security concerns about program exposure. The program's existence was revealed in 1977 when investigators discovered surviving documents that had escaped the systematic destruction of MK-Ultra records in 1973. Congressional investigations found that MKSEARCH had continued the most controversial aspects of its predecessor program, including human experimentation without informed consent and development of techniques for covert operations against both foreign targets and American citizens.
