The only good thing in this movie are aliens the main characters are held captive by after they take a puff of the titular antagonist. Everything else is boring and forgettable. The characters are bland, the acting's hokey and being a B-movie the effects are bad. Not the worst as far as B-movies go but still pretty bad. The story's about an evil alien bong who crashes on earth and plans to enslave the world leaving a bunch of stoners to stop it. Realizing how dangerous their foe is they forcibly recruit the original Evil Bong from the first 2 movies.

As you can guess things get incredibly stupid from this point on. The actresses who play the aliens are entertaining to watch but even they get tiresome because they do very little to further the plot. they're pretty much fluffers used to slowly turn their victims into weed. If you like stoners or so bad it's good movies than this's for you. Otherwise you can pass this joint up because you won't get the hit you're looking for.
