I am trying to gather all marijuana use, and dialogue of, in cartoons and animes dating back the past 20 years. Only one comes to mind for me, Samurai Champlou, the episode where the gate records keeper recounted a story of his first days at the job. Where an entire field was burned and how the gate was open for all that day, lost in a silvery purple haze. He said it was a revolution, but soon forgotten. I thought it was a near correct representation. Any others?
