CAPE ELIZABETH, Maine (AP) _ Police in Cape Elizabeth, Maine, are investigating an incident in which a student brought marijuana-laced cookies to the high school, leading to the suspension of nine students.

Superintendent Meredith Nadeau said it's unclear if all the students who ate the cookies were aware that they contained marijuana. Some of them felt ill and went to the nurse's office.

The Portland Press Herald says the episode unfolded Dec. 7 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 distributed or sold drugs to be suspended for 10 days and face possible expulsion, an action that would require a hearing before the School Board. The names of the students are not being released.
