LSD occurs naturally in the Ergot mushroom: > The ergot fungus contains a number of highly poisonous and psychoactive alkaloids, including lysergic acid (LSD), which was synthesized from the ergot fungus in 1938 by chemist, Albert Hoffmann [1]
What the author means is that it's synthetically made these days. Psilocybin can also be synthetically made these days.
psychedelics are the best hope humanity treating refractory mental illness. I know at least 5 people personally that have embarked on psychedelic voyages to treat their demons. Some of them are renowned psychiatrists.
