Basically an excuse for Cheech and Chong to get into a series of marijuana adventures, "Up in Smoke" is a hoot from beginning to end. Pedro De Pacas (Cheech Marin) and Anthony "Man" Stoner (Tommy Chong) are a pair of slackers who wonder So Cal and Mexico looking for some weed, while the narcs look for any excuse to arrest them. There are some scenes that will probably make your eyes pop out, just due to the surprise factor. You just watch this sort of movie and think "The '70s...those were the good old days." Also, it was interesting seeing Strother Martin and Edie Adams as Chong's character's parents. Seeing as to how they were part of my grandparents' generation, I wouldn't expect to see them in a marijuana movie.
