Cops Searching for Culprit Who Left Pot Brownies in Michigan Elementary Teachers’ Lounge [VIDEO]

Police in Oakland County are wondering if it was an adult or a student that slipped a plate of pot-laced brownies into the teachers' lounge at Spring Mills Elementary School in Highland Township.

One teacher was hospitalized, and two others were sickened after sampling the brownies, according to Detroit's WJBK-TV. Anyone who tampers with food and adds a narcotic can be charged with a felony.
