Mystical-type experiences occasioned by psilocybin mediate the attribution of personal meaning and spiritual significance 14 months later
In a Johns Hopkins study, 36 volunteers who had never taken hallucinogens were given high doses of psilocybin. They were told to “focus explicitly on the phenomenology of the drug experience rather than perform tasks”. 14 months after the trip, 67% of participants rated it as one of the top five most spiritually significant experiences of their lives, and six people said it was the single most spiritually significant experience. 64% said the experience increased their well-being and life satisfaction.
