High School (2010)

The day after high-school senior Henry Burke (Matt Bush) smokes his very first joint, his principal (Michael Chiklis) institutes a mandatory drug test for all students. Since he'll lose his college scholarship if he fails the drug test, Henry forms a half-baked plan. He teams up with his stoner pal Breaux (Sean Marquette) to steal some prime weed from a drug dealer named Psycho Ed (Adrien Brody), and uses it to spike the brownies intended for the school's bake sale.
