Benjamin Franklin started one of America's first paper mills with cannabis. This allowed America to have a free colonial press without having to beg or justify paper and books from England.
The United States Census of 1850 counted 8,327 hemp "plantations" (minimum 2,000 acre farms) growing cannabis hemp for cloth, canvas and even the cordage used for baling cotton. (This figure does not include the tens of thousands of smaller farms growing cannabis, nor the hundreds of thousands—if not millions—of family hemp patches in America.)
In 1942, after the Japanese invasion of the Philippines cut off the supply of manila (Abaca) hemp, the U.S. government distributed 400,000 pounds of cannabis seeds to American farmers from Wisconsin to Kentucky, who produced 42,000 tons of hemp fiber annually for the war effort until 1946. In 1942–43 farmers were made to attend showings of the USDA film Hemp for Victory, sign that they had seen the film and read a hemp cultivation booklet. Farmers from 1942 through 1945 who agreed to grow hemp were waived from serving in the military, along with their sons; that's how vitally important hemp was to America during World War II.
The paintings of Rembrandt, Van Gogh, Gainsborough, etc., were primarily painted on hemp canvas, as were practically all canvas paintings.
