LSD

The zoologist at University of Tubingen in Germany gave a bunch of spiders some LSD.

And there it was before my eyes—a real trip in those brain-buzzing LSD colors.

At the time they made LSD illegal in 1970—and by extension other psychedelics—MDMA was not included.

LSD, an illicit drug with a serious stigma, was once the darling of the psychotherapy world.

But with LSD, because it was countercultural, and because it was used as an experimental drug, it was not marketed properly.

It is common to have a bad psychological reaction to LSD, mescaline, and psilocybin.

Lysergic acid (LSD), mescaline, and psilocybin cause illusions and hallucinations.
