Two middle school students in Cabarrus County have been charged with bringing THC edibles to school and selling them to other kids, according to the Concord Police Department. Police said they also found psilocybin mushrooms, more commonly know as magic mushrooms.

On Friday, school officials sent seven students at C.C. Griffin Middle School in Concord, North Carolina, to the hospital after they ate the THC Rice Krispy Treats, police said. THC is the active ingredient in marijuana.

The episode began midday Friday. At 12:33 p.m., Concord police got a call from the school "after several students at C.C. Griffin Middle School had negative reactions to ingesting an unknown substance," the department said. But it turns out the students all knew what they were eating, police said. 

"All the students who ate a piece of the rice krispy treat and who spoke with police admitted to knowing that they were eating a THC edible," according to a news release from the Concord Police Department. 

The seven students who got high on the edible were taken "for observation" to Atrium Health Cabarrus.

Police worked with school administrators to investigate the edibles.

"Investigators interviewed several students and learned that this was a planned activity. Two students shared with classmates that they had access to THC edibles, and in advance of Friday, some students made an agreement to buy some of those edibles," police said. 

The students brought them to school on Friday, and some students shared the edibles, according to police. Some students also told police that they ate psilocybin mushrooms at school too, police said. 

Police charged two juveniles: one with "two counts of possession with intent to deliver a Schedule VI drug, and a second "with one count of possession with intent to deliver a Schedule I drug."

The department said it would not release the names of the students because of their age. Police said they continue to investigate and hope to find the original source of the drugs.
