according to a study by Johns Hopkins researchers;
"People who had mystic experiences while taking the mushrooms were more likely to show increases in a personality trait dubbed “openness,” which is related to creativity, artistic appreciation and curiosity, according to the study in the Journal of Psychopharmacology. The change was still in place a year later, suggesting a long-term effect.
“The remarkable piece is that psilocybin can facilitate experiences that change how people perceive themselves and their environment,” said Roland Griffiths, a study author and professor of psychiatry and behavioral science at Johns Hopkins University of Medicine in Baltimore. “That’s unprecedented.”
Magic mushrooms, also known as “shrooms,” are hallucinogens native to tropical and subtropical regions of South America, Mexico and the U.S. The fungi were favored by former Harvard psychologist Timothy Leary, who founded the Harvard Psilocybin Project, and explored by ‘60s writer and anthropologist Carlos Castaneda. They are typically eaten but can also be dried and smoked or made into a tea.
Openness is one of five major personality factors known to be constant throughout multiple cultures, heritable in families and largely unvarying throughout a person’s lifetime. The other four factors, extroversion, neuroticism, agreeableness and conscientiousness, were unchanged by being dosed with the hallucinogenic mushrooms, the study found. This is the first finding of a short-term intervention providing a long-term personality change, researchers said. "
