Did you know America's most beloved K-9 Scooby Doo and his faithful owner Shaggy partook in this ritual long before it was considered a trendy holiday!? Norville 'Shaggy' Rogers and his faithful Great Dane companion Scooby-Doo allegedly were pot heads! This was the premise for the cartoon show.
"The four teenage lead characters of Scooby-Doo were inspired by four of the main characters from the 1959-63 American television sitcom The Many Loves of Dobie Gillis, with Shaggy having been derived from the character Maynard G. Krebs, as played by Bob Denver. Maynard's beatnik-style goatee, general appearance, and use of the word "like" as a form of punctuation all found their way into the character of Shaggy, with the base personality of the character updated to make him a hippie rather than a beatnik" -Shaggy Rogers Wikipedia excerpt.

Google or Wikipedia the history and you will be amazed at what you find out! Disney and Pixar are still utilizing this strategy to the day. Though not with cannabis but relative other adult themed topics. What better way to get parents and kids involved in an animation all at once?
