LSD was first produced or discovered by a German Chemist in the mid 30's and sat on a shelf until the Yanks hoovered up the research papers at the end of WW11. In the mid 50's it was given to UCLA in California as a research project on behalf of the CIA and US Army to test if the drug would dis-able enemy troops. About 1962 the CIA canceled the contract. A part of the contract were test on troops in field exercises. I have seen film of similar results of US Troops who had taken LSD
Unfortunately or not, it your choice the research staff and students enjoyed the mind enhancing properties and continued to use the substance which then coincided with the rise of Flower Power etc at the same period. Thats the very brief history
