The film received lukewarm reviews. The average was 52% positive on Rotten Tomatoes, and earned a score of 55 from Metacritic. After the film's premiere, the duo appeared on The Daily Show with Jon Stewart. Both expressed happiness over the film's good critical response, and claimed they were "shooting for cult film status".
Kevin Crust of the Los Angeles Times said "[The movie] might best be enjoyed in an enhanced state of consciousness, a herbal supplement, and we aren't talking ginko biloba." Stephen Rae of The Philadelphia Inquirer said that the frequent drug-use in the film gives "the term potty humor a new meaning."
Michael Phillips criticized the frequency of the drug-use by saying: "This may be the problem. Pot rarely helped anybody's comic timing." Stephen Holden of The New York Times suggested that the film could be viewed as a "jolly rock 'n' roll comedy", but he also described the progression of the film as being a "garish mess."
