One of the most redeeming features of the movie is the endless parade of cameos. Many of the guest stars portray classic figures in the pantheon of potheads: Jon Stewart is the enhancement smoker, convinced that every activity is better while high; Snoop Dogg is the scavenger, the chronic mooch; Willie Nelson plays the “back in the day” smoker who spends his time recalling how in his day a dime bag actually cost a dime; Steven Baldwin is the MacGuyver smoker able to make smoking implements out of ordinary items; Janeane Garofalo is the artist who’s only creative when she smokes.
