The U.S. Food and Drug Administration (FDA) is investigating a food poisoning outbreak involving seizures and other severe symptoms and has warned the public not to eat the suspected products; specifically, mushroom-based chocolates and candies that are marketed as a way to “microdose” (implying a drug-like effect), but also claim not to contain psychedelic substances.

As of June 13, 2024, FDA and the U.S. Centers for Disease Control and Prevention (CDC), in collaboration with America’s Poison Centers and state and local partners, have identified a total of 12 connected cases of illness, including ten hospitalizations, across eight states (Alabama, Arizona, Indiana, Kentucky, Missouri, Nevada, Pennsylvania, and South Carolina). Patients reported experiencing seizures, central nervous system depression (i.e., loss of consciousness, confusion, and sleepiness), agitation, abnormal heart rates, hyper- and hypotension, nausea, and vomiting. In some cases, intubation was required. The most recent onset of illness was June 9, 2024.
