Cheech Marin and Thomas Chong prove to be irresistible anti-establishment figures in this consistently amusing dum-dum comedy.

| Original Score: 3/4 | Aug 30, 2021

Classic stoner comedy has drugs, language, sex.

| Original Score: 4/5 | Jul 17, 2019

a shaggy slice of slacker comedy, and while no one will mistake it for a particularly well-made movie, it is imminently likeable and repeatedly watchable

| Original Score: 3/4 | Apr 26, 2018

The funniest of all the Cheech and Chong movies, Up in Smoke provides a feast of gags for the sympathetically minded.

| Original Score: 3/5 | May 7, 2008

What's lacking in Up in Smoke is a cohesiveness in both humor and characterization.

This Cheech and Chong weed comedy was dismissed by most critics (and parents) but it was embraced by young viewers and launched the subgenre of "stoner" comedies way before Linklater made Slacker.

| Original Score: C+ | Apr 12, 2008

As far as comedic ingredients go, weed is not so much a surefire laugh-getter as it is a free-floating lubricant capable of setting off wicked complications.

| Original Score: 2.5/4 | Sep 5, 2007

Cheech & Chong had their act down pat by '78 and turned out to be a natural movie-comedy team.

| Original Score: B | Apr 9, 2007

As the most fun comes not from watching the movie but from recalling great lines later, it would seem that the audio success of C & C has not translated too well into visuals.

Up in Smoke is the world's most revered -- and most idiotic -- drug movie.

one joke stretched too far

Full Review | Original Score: 2/5 | Nov 8, 2004

A cult drug movie that lacks decent acting, script or direction.

| Jul 8, 2003

The duo wrote the genial script about the never-ending search for great pot, and a good supporting cast co-stars.
