In new research that will almost certainly create controversy, scientists working with the hallucinogen psilocybin -- the active ingredient found in "magic mushrooms" -- have found that a single dose of the drug prompted an enduring but positive personality change in almost 60 percent of patients.
Specifically, tests involving a small group of patients in a strictly controlled and monitored clinical setting revealed that, more often than not, one round of psilocybin exposure successfully boosted an individual's sense of "openness." What's more, the apparent shift in what is deemed to be a key aspect of personality did not dissipate after exposure, lasting at least a year and sometimes longer.
