I don't have a list
but first thing that comes to mind is MK Ultra.
I wasn't around back then, I'm guessing it was discussed before the files were released in 1975. I sure as hell would've talked about the government giving me acid and doing weird mind experiments on me if I were a participant
on the other end, If someone told me the CIA was secretly testing LSD on people and doing wild-shit experiments with it back then I might'a thought they were a loon and told them to tighten their tinfoil hat
interestingly enough, apparently, the CIA destroyed a lot of MK Ultra files as a result of a panic caused by watergate
