At the beginning of the movie, two kids are playing a prank on a third by dropping him in the pool, and they film it on camera. A little later, the assistant dean is watching it on some "youtube similar site", but the point of view is the movie camera, not the kids' camera, who presumably uploaded the movie.

Henry's black-eye changes shades inconsistently throughout the film.

The effect of cannabis in humans is poorly represented. Cannabis when ingested should take at least 30 minutes (usually more) for the effects to be felt, however in the movie characters often seem to feel the effects right after ingesting. The effects themselves are also exaggerated or wrong. Cannabis don't usually cause people to behave so weirdly. If characters felt more relaxed and sleepy instead, it would have been much more realistic.
