Today, April 20th, is an unofficial holiday for the cannabis cabal. Some celebrate privately, some join together to smoke en masse, but ceremonies usually culminate right around that magic minute, 4:20.

Weed and its culture have long been feted on TV. Among cable's generally damning portrayals of potheads, some shows persist a positive point of view on the drug, characterizing its effects as humorous and harmless. In honor of this historic day, here is a brief sampling of ganja's onscreen glory.
