Two University of Colorado students have been arrested for allegedly giving brownies laced with marijuana to their classmates and instructor without their knowledge.

FOX News Radio's Courtney Kealy reports:

According to Ryan Huff, a spokesman with the University of Colorado Police Department, two students and the class's professor were hospitalized and five other students became ill after eating the brownies.

(Huff) "This is no laughing matter, they may have viewed it as a prank."

Huff said 21-year-old Thomas Ricardo Cunningham and 19-year-old Mary Elizabeth Essa baked the brownies as part of 'bring food to class' day.

(Huff) "They had baked these brownies with THC, the active ingredient in marijuana and had served them to the class."

Both Cunningham and Essa were arrested Saturday and face felony charges.
