In a John Hopkins study, a majority of people who took a single dose of psilocybin were more imaginative, sensitive, and tolerant towards others for months afterward. In other words, psilocybin needs to remain illegal because it’s a threat to society. Via MedPage Today:
Many individuals who took a single dose of psilocybin — the active ingredient in what the drug culture calls “magic mushrooms” — showed alterations in personality characteristics, largely for the better, that persisted for more than a year, a prospective scientific study showed.
Participant…tended to show increases in the personality dimension known as openness, according to Katherine A. MacLean, PhD, and colleagues at Johns Hopkins University. Openness is generally considered a positive characteristic and includes such traits as aesthetic appreciation and sensitivity, imagination, intellectual engagement, and awareness of feelings in themselves and others.
The findings were consistent with previous studies and anecdotal reports from psilocybin users, who have said the drug changed their interactions with the world long after the acute effects wore off, MacLean and colleagues said.
