jimbones Reviewed by jimbones on . HISTORY OF 4:20! I have this weed book and it says; 4:20 came from California high schools students during the Greatful Dead scene. It grew in popularity there and then moved through out the US and then on to being a national weed thing!! I quess the would be in like the early 60's Has anyone else heard something different?
