Our Mission — Primary-Source Cannabis History

HistoryOfCannabis.org exists to replace mythology with documents. We follow the primary sources — congressional hearings, court records, archival collections — wherever they lead.

Why This Site Exists

Cannabis history has been told badly, from both sides, for most of the last century.

Prohibitionists built a propaganda apparatus on racial panic, fabricated crime stories, and sensational exploitation films — then sold it as public health. Harry Anslinger's Bureau of Narcotics planted newspaper stories, maintained a "Gore File" of racially framed atrocity narratives, and pushed a tax act through Congress in under two hours of hearings. The documentary record of this apparatus is extensive, housed at Pennsylvania State University and the National Archives, and is damning on its own terms.

Cannabis advocates, led by Jack Herer's influential 1985 book The Emperor Wears No Clothes, responded with an industrial conspiracy theory — Hearst, DuPont, Mellon, and Anslinger colluding to suppress hemp to protect timber and synthetic-fiber interests. Herer's instincts about institutional incentives were sharper than his evidence. The conspiracy has real components and fatal chronological problems. The Popular Mechanics article he built on appeared six months after the Tax Act was signed. Hearst was a buyer of newsprint, not a seller. The founding-father-smoked-it claims are false. The Gutenberg hemp-paper claim is false.

Both mythologies have crowded out the actual history — a history that is recoverable from primary sources and, in many cases, freely available online.

Our Method

Every factual claim on this site is traced to a specific primary source: a congressional hearing transcript, a court decision, a scientific paper, an archival collection, a presidential recording, or a government document. Where we rely on secondary sources — the scholarship of Bonnie and Whitebread, Musto, McWilliams, Campos, Fisher, and others — we name them and distinguish their interpretations from the underlying documents.

Where popular claims conflict with the documentary record, we follow the documents. Where evidence is uncertain, we say so. Where frequently cited quotations cannot be verified in primary sources, we flag them explicitly. We correct prohibitionist propaganda and activist mythology with equal rigor.
