  • Evaluate the evidence for the DuPont/Hearst connection
  • Connect the 1937 legislation to current scheduling debates

Outline

Part 1: The Primary Sources: Popular Mechanics February 1938. Mechanical Engineering 1938. USDA Hemp for Victory (1942). 1937 Congressional testimony, full record.

Part 2: The Three Arguments: Industrial/economic: hemp as competition for petrochemical synthetics. Racial: Anslinger's documented racial targeting. Scientific: the fraudulent studies and what they actually showed.

Part 3: What the Documents Prove vs. What Advocates Claim: The Herer problem: strong evidence, sometimes overstated inference. How to use the material responsibly.

Part 4: The Current Landscape: From Marihuana Tax Act to CSA. The Denver 2019 vote. What decriminalization vs. legalization means. The neurodiversity argument.
