Psychedelic mushrooms can do more than make you see the world in kaleidoscope. Research suggests they may have permanent, positive effects on the human brain.

In fact, a mind-altering compound found in some 200 species of mushroom is already being explored as a potential treatment for depression and anxiety. People who consume these mushrooms, after “trips” that can be a bit scary and unpleasant, report feeling more optimistic, less self-centered, and even happier for months after the fact.
