In a follow-up to research showing that psilocybin, a substance contained in "sacred mushrooms," produces substantial spiritual effects, a Johns Hopkins team reports that those beneficial effects appear to last more than a year.
Writing in the Journal of Psychopharmacology, the Johns Hopkins researchers note that most of the 36 volunteer subjects given psilocybin, under controlled conditions in a Hopkins study published in 2006, continued to say 14 months later that the experience increased their sense of well-being or life satisfaction. "Most of the volunteers looked back on their experience up to 14 months later and rated it as the most, or one of the five most, personally meaningful and spiritually significant of their lives," says lead investigator Roland Griffiths, Ph.D., a professor in the Johns Hopkins departments of Psychiatry and Behavioral Sciences and Neuroscience.
