Prior to the Marihuana Tax Act of 1937, which US companies were the main beneficiaries in the timber, cotton, and synthetic-fiber industries?

Before the Marihuana Tax Act of 1937, the main beneficiaries in the timber, cotton, and synthetic-fiber industries in the United States were large companies and corporations that dominated these industries. These companies were mainly based in the northeastern and southern regions of the country.

In the timber industry, companies such as Weyerhaeuser, Georgia-Pacific, and International Paper were among the largest producers of timber products.

In the cotton industry, companies such as J.P. Stevens, American Cotton Manufacturers, and the American Cottonseed Oil Company, were among the leading producers of cotton and cotton-based products.

In the synthetic-fiber industry, companies such as DuPont, Monsanto, and Union Carbide, were among the leading producers of synthetic fibers such as nylon and rayon.

These companies, along with others in these industries, had a significant influence on the economy and politics of the United States at the time and would have been negatively impacted by the growth of hemp as a competitor. They could have seen hemp as a threat to their profits and lobbied for its restriction and prohibition.

It's worth noting that the political and economic situation at the time, combined with the misinformation campaign led by the Federal Bureau of Narcotics, led to the restriction of cannabis, and it's not necessarily the case that these companies were the only or main reason for the restrictions.
