People who receive life-threatening cancer diagnoses and find themselves battling depression and anxiety might consider munching on magic mushrooms, and that's not coming from a snake oil salesman. Scientists at the Johns Hopkins University School of Medicine announced last week at the annual meeting of the American College of Neuropsychopharmacology that a single dose of the hallucinogenic ingredient, called psilocybin, appears to have a protective effect that lasts for an astonishing six months, per a press release. Found in some 200 mushroom species, psilocybin can give users hallucinations, nausea, and a distorted sense of time.
