ANNAPOLIS, Md. (AP) -- A teenager who brought a pot brownie into class panicked when his teacher asked him for a piece of the treat, so he obliged and shared the baked good. Things went downhill from there, and now the 17-year-old is facing criminal charges. The student didn't tell the teacher that the brownie contained marijuana. After eating her piece, the teacher began feeling ill and acting disoriented, and she was brought to the nurse's office at Broadneck High School in Annapolis on Monday, police said. The teacher told police that the student had given her the brownie during third period and that she suspected it contained marijuana. The student was charged with juvenile counts of administering a dangerous substance, assault, and reckless endangerment. Police did not release his name, and they say he was released to a guardian.
