It is not just the pharmaceutical cartel and Fraudulent Devious Ass-holes (FDA) that want this to stay out of the mainstream.

The decision of the United States Congress to pass the Marijuana Tax Act of 1937 was based on hearings, reports and in part on testimony derived from articles in newspapers owned by William Randolph Hearst, who had significant financial interests in the timber industry, which manufactured his newsprint.

DuPont played a huge role in the criminalization of cannabis. In 1938, DuPont patented the processes for creating plastics from coal and oil and a new process for creating paper from wood pulp. If hemp had been largely exploited, it would have likely been used to make paper and plastic (nylon), and would have decimated DuPont's profits as the method of collection only required simple farm machinery as opposed to logging, drilling or mining equipment.

Andrew Mellon of the Mellon Bank was DuPont's chief financial backer and was also the Secretary of the Treasury under the Hoover administration. Mellon appointed Harry J. Anslinger, who later became his nephew-in-law, as the head of the Bureau of Narcotics and Dangerous Drugs (FBNDD) and the Federal Bureau of Narcotics (FBN), where Anslinger stayed until 1962.

USDA Bulletin No. 404, reported that one acre of hemp, in annual rotation over a 20-year period, would produce as much pulp for paper as 4.1 acres (17,000 m2) of trees being cut down over the same 20-year period. This process would use only 1/4 to 1/7 as much polluting sulfur-based acid chemicals to break down the glue-like lignin that binds the fibers of the pulp, or even none at all using soda ash. The problem of dioxin contamination of rivers is avoided in the Hemp paper making process, which does not need to use chlorine bleach (as the wood pulp paper making process requires) but instead safely substitutes hydrogen peroxide in the bleaching process. ...

If the new (1916) Hemp pulp paper process were legal today, it would soon replace about 70% of all wood pulp paper, including computer printout paper, corrugated boxes and paper bags
