The Statesville Police Department says in a statement that a Davis Regional Medical Center employee brought the baked goods to work Sunday evening.
The six people who ate the cookies were immediately treated in the emergency department. Police say testing showed all six had ingested THC, the main psychoactive component in marijuana.
The employee told police they didn't know the sweets contained pot. An investigation later revealed that a family member had made them using cannabis-infused oil and didn't intend for them to be for the hospital staff.
The employee isn't facing charges.
