Severe health outcomes tied to mushroom-based psychoactive microdosing products

January 16, 2025

In June 2024, researchers identified a cluster of cases of severe adverse health effects, including neurologic and cardiac signs and symptoms, after ingestion of Diamond Shruumz–brand chocolate bars in Arizona. These products are labeled to include psychoactive mushroom extracts. The investigation prompted a nationwide product recall and public health response with detection of 180 cases in 34 states.

Edible products marketed as containing mushroom-based psychoactive substances could provoke life-threatening illness. CDC urges the public to stop consuming Diamond Shruumz–brand products and exercise caution when consuming other products reported to contain mushroom-based psychoactive substances.
