Hemp for Victory?
I figure this video will stimulate some potentially useful discussion. It features portions of an interesting WWII-era production, titled Hemp for Victory, made by the U.S. government to encourage U.S. farmers into the cultivation of hemp to fill the escalating demand for industrial fibre during the war. This was not too long after the U.S. had introduced, during the height of the Great Depression, the 1937 Marihuana tax, which had had the opposite effect. (It goes to show the power that government policies can wield in rapidly influencing social priorities.)
