Up in Smoke

⁣An unemployed pot-smoking slacker and amateur drummer,
Anthony Stoner (Tommy Chong) ditches his strict parents and hits the
road, eventually meeting kindred spirit Pedro de Pacas (Cheech Marin).
While the drug-ingesting duo is soon arrested for possession of
marijuana, Anthony and Pedro get released on
a technicality, allowing them to continue their many misadventures and
ultimately compete in a rock band contest, where they perform the
raucous tune "Earache My Eye."
