The classic work on this is "Acid Dreams: The Complete Social History of LSD: The CIA, the Sixties, and Beyond" by Lee & Shain. The Chapter "In the Beginning There Was Madness" covers the crazy era of MK-ULTRA (and the Frank Olson case, in which the CIA fed LSD to MKULTRA collaborators in the biological warfare program, where Olson worked - he then had a breakdown of some sort and wanted to quit the program and perhaps go public, so the CIA hit him in the head with a hammer and threw him out of a high-rise (probably, anyway) and called it a suicide for several decades).
