Recently, 36 people who had never taken hallucinogens before gave them a try. The pill they took launched a daylong psychedelic journey, sometimes fantastic, sometimes frightening. When it was over, a few who took the drug said it was the most meaningful experience of their lives, as momentous as the birth of a first child or the death of a parent. Others wished never to repeat. The drug they took was psilocybin, the hallucinogenic molecule found in "magic" mushrooms. This article deals with a study at the Johns Hopkins University Bayview Medical Center that explored the drug's ability to induce a mystical state. In this article, the author also discusses other studies on psilocybin, such as those from Timothy Leary, a psychologist at Harvard University and Dr. Charles S. Grob, a psychiatrist at Harbor-UCLA Medical Center.
