Did You Know?

The most famous--or notorious--of the psychedelic drugs is LSD, a compound that can be obtained from various mushrooms and other fungi but is usually created in the lab. The other well-known psychedelics are psilocybin (likewise obtained from fungi) and mescaline (obtained from peyote cactus). How psychedelics produce their effects is still fairly mysterious, partly because research ceased for almost 20 years because of their reputation, but scientists are determined to find the answers and much research is now under way. Psychedelics are now used to treat anxiety in patients with cancer, and are being tested in the treatment of such serious conditions as severe depression, alcoholism, and drug addiction.
