Charles Ronald Hart Aschenauer, 16, of Paw Paw Road in Gulf, was arrested Wednesday by a school resource officer at Chatham Central High School.
Investigators said they looked at surveillance video after a teacher became nauseous and Aschenauer was seen putting something in a drink before the teacher drank it.
Aschenauer was charged with felonious distribution of certain prohibited foods. He was released on bond Wednesday.
Officials said the teacher will be okay.
Aschenauer is due in court April 25.
