All three students were hospitalized but have since been released.
"I can't confirm if they knew it or not," Cheeseman told WVEC. "I would like to air (err) on the side of caution and say they did not know."
The Perquimans County Sheriff's Office has charged the student accused of bringing the edible to school with drug possession and selling and delivering drugs.
The other students could face a 10-day suspension, 365-day suspension, expulsion, or other consequences.
