There is a worldwide shortage of LSD, according to researchers from the University of Michigan. Fifty years ago, lysergic acid diethylamide could be found in every high school and college campus across America, but scientists claim that is no longer the case, with a recent survey indicating a decline in teenage trip enthusiasts.

This lack of acid use, however, is not due to fears over the drug’s side effects, but merely fewer chemists are manufacturing the drug. ‘It looks to me like lack of availability has played a major role in the decline of this drug,’ Lloyd Johnston, part of the University of Michigan research team, told io9.

There is speculation that the overall decrease in acid production stems from the arrest William L Pickard, a chemist and Buddhist priest who had such a LSD stockpile at the time he was arrested that it immediately brought its availability across the planet to a near screeching halt.

As for the amateur chemist, fewer of these people are manufacturing LSD these days because certain vital ingredients, like ergot alkaloid, are nearly impossible to get one’s hands on unless they have affiliation with some eastern European nations.

EDITOR’S NOTE: Initially, this story incorrectly identified David Nichols as a major LSD manufacturer and claimed that he was arrested. Neither were true and we apologize for the error.
