In 1963, as part of a military experiment, British soldiers were given a hit of LSD and then sent out onto the field.
Needless to say, what happened next is absolutely hilarious. As it turns out, when soldiers are high on LSD they have absolutely no desire for war or violence.
Fifty minutes after taking the drug, radio communication had become difficult, if not impossible. But the men are still capable of sustained physical effort; however, constructive action was still attempted by those retaining a sense of responsibility despite their physical symptoms. But one hour and ten minutes after taking the drug, with one man climbing a tree to feed the birds, the troop commander gave up, admitting that he could no longer control himself or his men. He himself then relapsed into laughter.
