World War II is the most widespread war in history, which involved a majority of the world’s countries from 1939 to 1945. The Second World War began when Hitler invaded Poland in 1939, driving Great Britain and France to declare war on Germany, which started the six years of conflict, taking more lives and destroying more property around the world than any other previous war. In order to continue fighting this long war, the military, navy, and air force required unlimited resources, which included cannabis.

Even during the most difficult time like the Second World War, cannabis was used all across the world. First, the United States government actually encouraged farmers to grow more hemp by producing the movie “Hemp for Victory” in 1942. The film shows the history of hemp, how the plant is grown, and how it is processed into rope, cloth, cordage, and other products necessary for the war. Hemp fiber was crucial to produce strong military equipment in Japan, where it was considered a war material, “During World War II, there was a saying among the military that without cannabis, the war couldn’t be waged.” The psychological effects of marijuana were also used during WWII as a sort of truth serum that would relax and distract prisoners enough to provide useful information, so the truth is that cannabis was utilized almost everywhere during World War II.
