Investigators have found THC in a food sample that was taken from a Georgia middle school where more than two dozen students were taken to the hospital after eating snacks and candy last week, the Atlanta Journal-Constitution reported. THC is the psychoactive component in marijuana.

What's the story?

On Valentine's Day, 28 students at Sandtown Middle School in Atlanta were treated at various hospitals after they reported feeling "nauseated or disoriented."

The Georgia Bureau of Investigation released lab results of 46 food items that it received on Tuesday from Fulton County Schools Police Department.

"Test results of one of the items that has the appearance of cereal has revealed the presence of THC," the GBI said in a statement released Thursday.

What did the police report say?

The Fulton County school police report stated that the children had eaten heart-shaped lollipops, Rice Krispy treats and other snacks on the day of the incident, according to the Journal-Constitution.

Some of the children reported hallucinations, disorientation and watery red eyes, according to the police report obtained by the newspaper. Others were "frantically crying on and off."

"They couldn't tell me where they were at the time nor could they explain what had happened to them," the police report said.

By Monday, all of the sickened students had been released from the hospital, according to the Journal-Constitution.

Where did the THC-laced treats come from?

It is not yet clear who brought the treats to school but investigators believe the drug-laced edibles were brought to school by a student or students.

Authorities want to know whether or not those who brought the snacks to school knew they contained THC.

"We will investigate this thoroughly and will see this through to the fullest extent possible," Shannon Flounnory, executive director of the district's safety and security division, said in a statement Thursday.
