Overview

• A JAMA Network Open paper published September 11 analyzed 12 gummies and a chocolate purchased from Portland gas stations and convenience stores.
• Testing by a state-licensed laboratory and follow-up analyses found no psilocybin in any product.
• Seven items contained undeclared substances including caffeine and THC, indicating widespread mislabeling.
• Analysts identified the synthetic psychedelics mipracetin and 4-hydroxy-diethyltryptamine, compounds with little to no human safety data.
• Two gummies contained psilocin that researchers say likely came from a laboratory source, reinforcing calls for better analytical methods, clear labeling rules, and coordinated surveillance following prior CDC reports of severe illnesses linked to retail edibles.
