Hemp And Iowa

In 1917, domestic production of industrial hemp totaled 41,200 acres in response to fiber shortages during WWI. Due to the Marijuana Tax Act of 1937, hemp production was essentially closed off across the Midwest until 1942. When Philippines fell to Japanese forces in 1942 in World War II, the Department of Agriculture and the US Army urged farmers to grow hemp fiber cultivars. Tax stamps for cultivation of fiber hemp began to be issued to farmers. Without any change in the Marijuana Tax Act, 400,000 acres (1,600 km2) were cultivated with hemp between 1942 and 1945. In 1943, Iowa grew nearly 48,000 acres of industrial hemp fiber cultivars. To this day, feral hemp (“ditch weed”) is descendant of these government-issued genetics. The last commercial hemp fields were planted in Wisconsin in 1957.
