Ken Kesey ,Owsley Stanley and the Grateful Dead , theres bound to have been acid all over the place ,
maybe it was supposed to be a specially 'interactive' module
At least the guy seemed to have a notion of what was happening to him after the trip started ,
I suspect military and government always had a side interest in letting the students go mad on drugs and just be creative for its own sake . Of course heroin and coke soon turned the peace and love into old fashioned slavery again . Its kind of ironic that the dope coming out of war torn Southeast East Asia ended up used by the US government to put down a revolution at home .
heres a classic noodley bit from the dead , sometimes they used do this for hours and hours on end ,
