It is unknown to what extent the agency's recommendations were used or for how long, but according to the same Senate report, the list drawn up by DIA included the use of "drugs such as sodium pentothal and demerol", humiliating treatment using female interrogators and sleep deprivation. Becker claimed that he recommended the use of drugs due to rumors that another intelligence agency, name of which was redacted in the Senate report, had successfully used them in the past. According to the analysis of the Office of Defense Inspector General, the DIA's cited justification for the use of drugs was to " detainee to cooperative state" and that mind-altering substances were not used.
