A new study by researchers at John Hopkins has found evidence that just one strong dose of hallucinogenic mushrooms can alter a person's personality for a year or more.
People given psilocybin, the compound in "magic mushrooms" that causes hallucinations and feelings of transcendence, demonstrated a more "open" personality after their experience, an effect that persisted for at least 14 months. Openness is a psychological term referring to an appreciation for new experiences. People who are more open tend to have broad imaginations and value emotion, art and curiosity.
"This is one of the first studies to show that you actually can change adult personality," said MacLean, a postdoctoral researcher at The Johns Hopkins University School of Medicine. The root of the change seems to be not the drug itself, but the mystical experiences that psilocybin often triggers. These profound, transcendent feelings feel no less real to people for being chemically induced, she said. "Many years later, people are saying it was one of the most profound experiences of their life," MacLean said. "If you think about it in that context, it's not that surprising that it might be permanent."
But this is a strictly do-not-try-this-at-home experiment, MacLean cautioned. The participants in the study were under close supervision during their session with the drug. Psychological support and preparation helped keep bad trips to a minimum, but many participants still reported fear, anxiety and distress after taking psilocybin.
"I could see how in an unsupervised setting, if that sort of fear or anxiety set in, the classic bad trip, it could be pretty dangerous," MacLean said, adding that the risk of unsupervised usage outweighs any potential reward.
It's not yet clear whether unsupervised usage would even result in the same changes in openness as seen in the study, MacLean said. The study group was small (only 51 people), and was already more religious and more open than the general population.
Clearly there's a need for more research and definitely this is not endorsing free use of hallucinogenics, but it's interesting nonetheless.
