In How Marijuana Became Illegal Bud Fairy writes:
During the same period, Du Pont was developing cellophane, nylon, and dacron from from fossil fuels. Du Pont held the patents on many synthetics and became a leader in the development of paint, rayon, synthetic rubber, plastics, chemicals, photographic film, insecticides and agricultural chemicals.
From the Du Pont 1937 Annual Report we find a clue to what started to happen next: "The revenue raising power of government may be converted into an instrument for forcing acceptance of sudden new ideas of industrial and social reoganization".
Ok, enter William Randolph Hearst. Hearst's company was a major consumer of the cheap tree-pulp paper that had replaced hemp paper in the late 19th century. The Hearst Corporation was also a major logging company, and produced Du Pont's chemical-drenched tree pulp paper, which yellowed and fell apart after a short time.
In Why is marijuana illegal? Pete Guither writes:
Hearst and Anslinger were then supported by Dupont chemical company and various pharmaceutical companies in the effort to outlaw cannabis. Dupont had patented nylon, and wanted hemp removed as competition. The pharmaceutical companies could neither identify nor standardize cannabis dosages, and besides, with cannabis, folks could grow their own medicine and not have to purchase it from large companies.
This all set the stage for…
The Marijuana Tax Act of 1937.
Is that an accurate description of the poltical realities of the time? Did the Marijuana Tax Act of 1937 pass because if lobbying by Dupont and Hearst for their commerical interests as paper producers?
