Psychedelic drugs like psilocybin, or magic mushrooms, have been used throughout human history. But it’s only in the last few decades that researchers have been examining them as a potential tool for treating an array of mental health issues. Albert Garcia-Romeu, a Johns Hopkins behavioral pharmacology researcher, talks with Stephanie Desmon about his research with psilocybin, the promising outcomes, and how approval and proper regulation could lead to a whole class of psychedelic drugs used responsibly as treatment for mental health disorders.
