The US government has put serious money into this stuff, and the most they got out of it was "you can give somebody a mental illness by randomly drugging them."

I don't agree with your characterisation that they concluded "you can give somebody a mental illness by randomly drugging them"; they concluded "A statistically significant laboratory effect has been demonstrated in the sense that hits occur more often than chance."
