MKUltra
Project MKUltra was a human experimentation program carried out by the CIA with wide-ranging objectives, including study of the use of torture and the possibility of brainwashing. The program was carried out over several decades across multiple continents and involved the use of psychedelics, electronic shocks, sensory deprivation methods, and other methods of torture. The program was revealed by the Church Committee in 1975, and was ostensibly halted. However, most of the documents in CIA storage relating to MKUltra were destroyed.
Drugs
Project MKUltra mainly used LSD-25 and Mescaline for purposes of manipulating the subjects.[1]

Theodore Kaczynski is discussed to be one of the victims of MKUltra and exposed to inhumane stress situations as part of a experiment conducted by Henry A. Murray. <ref>https://www.thecrimson.com/article/2000/7/14/murray-center-seals-kaczynski-data-plondon-buried/</a>
