R.I.P. Scout26
LSD was tested extensively on troops of various militaries in the 60's and 70's, I'm not sure what the purpose was.
In United States v. Stanley 483 U.S. 669 (1987), the United States Supreme Court found that a serviceman could not file a tort action against the federal government, even though the government secretly administered doses of LSD to the serviceman as part of an experimental program, because his injuries were found by the lower court to be service-related.
