Psilocybin is a naturally occurring compound found in over 200 species of mushroom and is currently regulated as a Schedule I drug with "no currently accepted medical use and a high potential for abuse" pursuant to the federal Controlled Substances Act (CSA). Notwithstanding that classification and description, a growing body of scientific and medical studies and trials indicates that psilocybin-assisted therapies provide benefits to those suffering from various health conditions. In fact, the U.S. Food and Drug Administration (FDA) itself has twice designated psilocybin as a "breakthrough therapy," meaning clinical evidence indicates that psilocybin therapy demonstrates substantial improvement over other available therapies for both major depressive disorder and treatment-resistant depression.
