In 1962, Oklahoma based researchers Louis Jolyon West and Chester M. Pierce decided to find out what happens when you give an elephant a massive quantity of LSD. They decided to give this particular elephant around 1000 times the standard human dose, just to make sure.
I know you’re hoping that the next sentence I write goes like this “30 seconds after the dose was given the elephant burst in to uncontrollable fits of laughter and danced for an hour and a half. He then donned a wizard’s hat and headed down the snooker hall whistling an obscure Right Said Fred tune.”
But this is what actually happened: the elephant keeled over and died almost immediately. It turns out elephants are particularly sensitive to LSD. Nice one.
