Before the Hippies of the 1960s discovered drugs and got high, there was the US Military high on the idea that drugs would let them control people's minds.
Here is a US military document entitled Experimentation Programs conducted by the Department of Defense That Had CIA Sponsorship or Participation and That Involved the Administration to Human Subjects of Drugs Intended for Mind-Control or Behavior-Modification Purposes prepared in 1977 by the General Counsel of the Department of Defense and released on May 6, 2010 after a Freedom of Information Act request.
Go read this document to find out how the hard-earned taxpayer dollars were spent on schemes to let the military "take control of your mind" and turn you into a zombie.
Sadly, this document doesn't cover the human tragedies created by these programs, i.e. the people killed, driven crazy, families wrecked, etc. You can get a taste of that by using Wikipedia to look up some of these programs and get some details: MKULTRA, MKDELTA, MKNAOMI.
