Quite honestly, I don't see how even fans of this film can give it a '10' rating. It's funny in parts, but personally, I found the movie a chore to get through. There's not much of a story going on, and it's principal appeal seems to be in catering to the stoner crowd that gets it's kicks in the kind of moronic behavior exhibited by Cheech Marin and Tommy Chong. Veteran character actors like Stacy Keach,Tom Skerritt and Strother Martin lower their personal standards to appear in this flick and not necessarily for the good, as they all present caricatures of the type of characters they're supposed to represent. For me, this couldn't be over and done with quick enough, but if you're a Cheech and Chong fan, have at it. Who am I to deny a meaningless hour and a half in your life?

Two stoners unknowingly smuggle a van -- made entirely of marijuana -- from Mexico to Los Angeles, with incompetent Sgt. Stedenko on their trail.Although Cheech and Chong made several films together, they will probably always be best remembered for this one, their first. There are so many moments that have since become a part of pop culture. The use of War's "Low Rider", the smoking of the Labrador... when watching it for the first time you might feel like you have seen it before.Those into drug culture may appreciate the film more, but being a stoner is certainly not required to laugh at the antics of these two luckless losers.

This is a great movie, I always watch it when I'm sad and it's turns my frown upside down. I really like it what Cheech and Chong live in their own world where everything is alright and almost everyone is happy and everything turns out okay. Cheech and Chong are funny they remind me of my neighbors, I wish Cheech and Chong lived next door so they could come over smoke a bowl and watch their movies with me. I liked that this movie took place in Los Angeles, because all movies are being in other countries. I think that Cheech and Chong Movies are good because they show the good that Latin people can be. People complain about this and other Cheech and Chong movies, but I think that they are extremely entertaining, if you watch a movie based on anything else you are missing the point.

Cheech and Chong movies will honestly never get old. This is the original movie that started it all and it is honestly the funniest of all they're films. This movie is entirely what the comedy of Cheech and Chong always was. This movie is the only movie in which Cheech and Chong do not play themselves as the titles characters, but still this movie is a laugh riot. A definite classic for all comedy genre fans to see. It may seem old school and not all teen sex related like todays comedies, but this is really what comedy is all about. This movie really hit it big and is still enjoyed today. Now that Cheech and Chong have reunited are we in for Up in Smoke 2 soon? Hopefully so.10/10
