Research: Yes, there’s magic in those mushrooms 

For years, Roland R. Griffiths had heard about the profound spiritual experiences of people who had ingested psilocybin, a hallucinogen that, if you came of age in the 1960s, you might recall as “magic mushrooms.” Anthropologists had described, sometimes rapturously, the effects of psilocybin, but Griffiths, a Johns Hopkins professor of psychiatry and behavioral biology, was skeptical. He knew of little rigorous clinical research in which psilocybin had been administered under appropriate laboratory conditions. After completing his own carefully constructed study of the drug, he is skeptical no more.
