Marijuana-laced cookies taken by a student to a Maine high school on a day ethics and values were being discussed have sickened some classmates. Nine students have been suspended, and police are investigating. Cape Elizabeth schools superintendent Meredith Nadeau says it’s unclear if all the students who ate the cookies were aware they contained marijuana. Some of them felt ill and went to the nurse’s office. The Portland Press Herald, reported Monday the episode unfolded Friday during a daylong event featuring speakers addressing the school district’s guiding values of “Community, Academics, Passion and Ethics.” School policy calls for a student who distributes or sells drugs to be suspended for 10 days and face possible expulsion, an action requiring a hearing before the School Board. The names of the students aren’t being released.
