When did humans first use cannabis?

Archaeological evidence confirms psychoactive cannabis use by at least 500 BCE. In 2019, researchers led by Meng Ren and Nicole Boivin identified THC breakdown products on wooden braziers from the Jirzankal Cemetery in the eastern Pamirs, dated to roughly 500 BCE (Science Advances, 2019). Industrial hemp use — fiber, textiles, cordage — dates back roughly 7,000 years in Neolithic China. The popular claim of cannabis use in 2737 BCE, attributed to the mythical Emperor Shennong, is legendary, not historical; the Shennong Bencaojing was compiled in the 1st–2nd century CE.

Was the Declaration of Independence written on hemp paper?

No. The signed engrossed Declaration of Independence is on parchment (animal skin), not paper of any kind. Thomas Jefferson's rough draft is on Dutch paper, most likely made of flax-linen rags. Early American rag paper sometimes included hemp fiber, but the founding documents themselves were not written on hemp paper. These myths circulate widely in hemp advocacy; they are not history.

Why was cannabis made illegal in the United States?

The scholarly consensus — Bonnie and Whitebread (1974), Musto (1973), Campos (2012), McWilliams (1990), Fisher (2021) — locates prohibition's causes in racialized moral panic (anti-Mexican, anti-Black, anti-Filipino); bureaucratic empire-building by the Federal Bureau of Narcotics after Prohibition's 1933 repeal; genuine if misguided public-health concerns; and Protestant moral-reform networks. The Hearst-DuPont-Mellon conspiracy theory has real components but collapses under chronological scrutiny.

Did Harry Anslinger really say "Reefer makes darkies think they're as good as white men"?

This quote has not been verified in any primary document. Penn State University Libraries, custodian of the Anslinger Papers, stated in a 2023 reference update that they cannot verify the quote in their holdings. The underlying racism is real and documented — a December 1934 FBN memo uses explicitly racist language, and Anslinger's congressional testimony and published articles consistently linked cannabis to Black and Hispanic Americans — but the most viral specific quotations are either apocryphal or latter-day paraphrases.

What was the Marihuana Tax Act of 1937?

The Marihuana Tax Act (Pub. L. 75-238) imposed a prohibitive $100/ounce tax on unauthorized cannabis transactions, effectively banning the drug. Hearings ran approximately two hours across five days in April–May 1937. The AMA opposed the bill — Dr. William Woodward testified that no evidence supported the claims. The House passed it after a floor debate of approximately 92 seconds. It was signed by FDR on August 2, 1937, and struck down by the Supreme Court in Leary v. United States (1969).

Was Reefer Madness official government propaganda?

No. Reefer Madness (1936) was produced as a cautionary drama and recut by exploitation producer Dwain Esper for the roadshow circuit. Wayne Hall's 2026 Addiction analysis documents that Esper approached Anslinger for endorsement in May 1938 — after the Tax Act had passed — and Anslinger refused and attempted to suppress the film as too sensational. It became iconic anti-prohibition satire after NORML founder Keith Stroup found a Library of Congress print in the early 1970s.

Why this site exists

Cannabis history has been told badly, from both sides. Prohibitionists built a propaganda apparatus on racial panic, bureaucratic ambition, and fabricated crime stories — and sold it as public health. Cannabis advocates, led by Jack Herer's influential but flawed The Emperor Wears No Clothes, responded with an industrial conspiracy theory that has real components but collapses under chronological scrutiny.

Both versions have crowded out the actual history. That history — recoverable from congressional hearings, court records, scientific papers, and archival collections — is more damning than Herer's conspiracy and more complex than either side prefers.

This site follows the primary sources. Where popular claims conflict with the documentary record, we follow the documents. Where evidence is uncertain, we say so. We correct prohibitionist propaganda and activist mythology with equal rigor.

What the evidence supports — the racial panic that drove prohibition, the bureaucratic empire-building, the 92-second House debate, the Nixon tapes, the Ehrlichman confession, the ACLU arrest data.
