Cheech & Chong are a Canadian comedy duo founded in Vancouver and consisting of Cheech Marin and Tommy Chong. The duo found commercial and cultural success in the 1970s and 1980s with their stand-up routines, studio recordings, and feature films, which were based on the hippie and free love era, and especially drug and counterculture movements, most notably their love for cannabis.
