History
The long, strange, and frequently misremembered story of a plant — from a 1619 law that ordered colonists to grow it, to the tonic on your great-great-grandparent’s medicine shelf. And the part worth bookmarking: the cannabis “facts” everyone repeats online, fact-checked and set straight. Short reads, every claim sourced.
A companion to our scroll-through timeline.
For most of American history, cannabis wasn’t contraband — it was rope, medicine, and a Victorian curiosity.
In 1619, the first General Assembly of Virginia at Jamestown ordered every householder to plant hemp — for the sailcloth and rigging that powered an age of sail. Massachusetts (1631) and Connecticut (1632) soon passed their own “grow-it” mandates. America’s first cannabis law was a command to plant it; its most famous modern one was built to stamp it out.
From the 1850s until 1941, cannabis was listed in the U.S. Pharmacopeia and sold over the counter — no prescription — by Parke-Davis, Eli Lilly, and Squibb, usually as an alcohol-based tincture for migraine, insomnia, and pain. It was quietly removed in 1941, at Harry Anslinger’s urging.
In 1857, American writer Fitz Hugh Ludlow published “The Hasheesh Eater,” a vivid cautionary memoir that helped spark a craze — mail-order “Hasheesh Candy,” and well-dressed gentlemen puffing Turkish hash pipes at the 1876 Philadelphia Centennial. (The lurid “hundreds of hashish parlors in New York” line traces to a single 1883 magazine story — enjoy it as period color, not a census.)
The Pure Food and Drug Act of 1906 didn’t ban cannabis — it required patent medicines to disclose “dangerous” ingredients. So for the first time, ordinary shoppers saw “cannabis” listed right beside alcohol, opium, and cocaine on the label of their cough syrup and sleep tonic, still sold without a prescription.
Prohibition didn’t arrive on the science. It arrived on fear, politics, and a carefully chosen word.
Cannabis had been in American medicine for decades — as “cannabis.” The smokable, recreational form arrived with Mexican immigrants after the 1910 revolution, and prohibition crusaders pointedly switched to the foreign-sounding “marihuana” to tie the drug to immigrants and stoke fear. Same plant, two names — one chosen to frighten.
Harry Anslinger ran the Federal Bureau of Narcotics for 32 years. To pass the 1937 Marihuana Tax Act he made openly racist claims and cited lurid “Gore File” crimes that researchers later showed were fabricated or misattributed (the case he leaned on hardest involved documented mental illness, not cannabis). The 1936 scare film later known as “Reefer Madness” fed the same panic.
Skeptical of the 1937 law, New York Mayor Fiorello La Guardia asked the New York Academy of Medicine to actually study marijuana. The 1944 LaGuardia Report concluded it was not the addictive, violence-inducing, gateway menace the government described. Anslinger denounced it as “unscientific,” halted research, and had it rebutted.
In 1942, after Japan cut off Asian fiber, the same government that had just taxed cannabis into oblivion produced a USDA film, “Hemp for Victory,” urging patriotic farmers to grow hemp for Navy rope and parachute webbing. For decades officials denied the film existed — until a copy surfaced in the National Archives around 1989.
During the long prohibition, cannabis didn’t disappear — it went to the hills, the hollows, and the Southern woods, kept alive by growers who risked everything.
In the late 1960s and ’70s, countercultural settlers moved into the rugged hills of Northern California — Humboldt, Mendocino, and Trinity counties, the “Emerald Triangle” — onto cheap land left behind by collapsing timber and fishing towns. They grew cannabis first for themselves, then as a cottage industry, perfecting “sinsemilla” (Spanish for “without seed”): unpollinated female flowers far stronger than the seedy imported “brick weed” of the day. By 1979, a California state senator told the New York Times marijuana was among the biggest crops in his district.
You weren’t imagining it. Through the 1980s the rural South and Appalachia — Kentucky, Tennessee, north Georgia — became major outdoor-growing country, with plots tucked into national forests in some of the poorest counties in America, an economy that picked up where moonshine left off. Georgia was in the thick of it: in 1983 the state’s strike force pulled up more than 660,000 marijuana plants “the old-fashioned way, by hand,” and a federal paraquat-spraying flight over the Chattahoochee National Forest drew protests and a court order. Kentucky’s legendary “Cornbread Mafia” — 70-plus growers across ten states, bound by a total code of silence — was broken up in 1989 with 182 tons.
The government fought back from the air. The DEA’s Domestic Cannabis Eradication program (from 1979) put National Guard helicopters over fields nationwide; California’s CAMP raids (from 1983) coined the very name “Emerald Triangle” and triggered lawsuits over low-flying choppers and roadblocks. The crackdown had an unintended consequence: it pushed growers off the hillsides and, by the 1990s, indoors — to the hydroponic grow rooms that would define the next era.
Prohibition could have erased cannabis’s diversity. Instead, a handful of obsessive growers preserved it — planting landrace seeds smuggled in from Afghanistan, Mexico, Thailand, and Colombia, and breeding stable strains like Skunk #1. As U.S. raids intensified in the late 1980s, breeders carried their seed stock to the Netherlands, where Dutch seed banks safeguarded much of the genetic library the legal industry is built on today.
The internet’s most-repeated cannabis “facts,” checked against museums, court records, and peer-reviewed history — and set straight. Every one is sourced.
The signed Declaration and Constitution are on parchment — treated animal skin — not paper of any kind. Even Jefferson’s working drafts were almost certainly linen-rag paper, not hemp. The hemp-paper claim traces to a 1985 activist book, not the historical record.
The popular tale — that DuPont, William Randolph Hearst, and Andrew Mellon plotted to outlaw hemp to protect nylon and paper — comes from a 1985 activist book, not historians. The decisive problem: the 1937 Act didn’t ban hemp. Fiber stayed legal, and U.S. acreage actually rose during WWII’s “Hemp for Victory.” The famous Popular Mechanics “Billion-Dollar Crop” article even appeared months after the Act passed. Historians attribute prohibition mainly to racialized fear of Mexican and Black Americans.
Virginia’s 1619 assembly did tell householders to “make trial” of hemp — but only those who already had seed, alongside flax and aniseed, with no stated penalty. In reality colonists preferred tobacco, so governments spent a century offering bounties to coax reluctant farmers. A 1682 law let hemp cover up to a quarter of a person’s debts — narrow, not “legal tender,” and nobody was jailed for refusing.
No original “Betsy Ross flag” survives — the attribution rests on an 1870 family speech — so there’s no fabric to even test. Early American flags were standardly wool bunting, with linen, cotton, and silk for finer ones. “The first flag was hemp” isn’t supported.
The original 1873 Levi’s riveted “waist overalls” were cotton — brown cotton duck and indigo-dyed denim. The Smithsonian holds an actual pair of the early brown-duck cotton trousers. The hemp version is a documented urban legend.
The “25,000 uses” figure comes from a single 1938 Popular Mechanics article — promotional optimism, not a documented inventory — and the “50,000” version is later inflation. Hemp is genuinely versatile (fiber, food, oil, building materials), but the round numbers are marketing, not data.
Ford did unveil a real plastic-bodied car in 1941 — but it was a soybean car on a steel frame, not hemp, and it was not hemp-fueled. The famous “an axe couldn’t dent it” demo is theatrical; on the first real strike the panel actually cracked.
There’s real truth here — the word spread with Mexican migration, and prohibitionists exploited its foreignness. But they didn’t invent it: “marihuana” was a genuine Mexican word for the plant, and even the “madness and violence” fears came north from Mexican discourse. They leveraged the foreign sound; they didn’t manufacture it.
The 1936 film (originally “Tell Your Children”) was financed by a church group, then bought and re-cut by an exploitation-film producer — not made by the government or Anslinger’s narcotics bureau. It reflected the era’s hysteria but only became famous as a 1970s cult comedy.
The idea that the Hebrew “kaneh bosm” in the holy anointing oil means cannabis is a real but minority hypothesis (first proposed in 1936). Most Hebrew-Bible scholars read the term as calamus, or sweet cane. Genuinely interesting and unsettled — not established fact.
He genuinely grew hemp at Mount Vernon, and a famous 1765 diary note frets he “began to separate the male from the female hemp… rather too late.” But that’s ordinary fiber farming — removing males to strengthen the stalks for rope — not a confession. There’s no evidence any founder smoked cannabis as a drug, and the viral Jefferson “smoking hemp on my veranda” quote is confirmed fake.
There’s no direct evidence Victoria’s physician prescribed her cannabis for period pain, and he joined her medical household when she was about 59. What is true: that physician, Sir John Russell Reynolds, publicly called cannabis “one of the most valuable medicines we possess.”
A 1971 Defense Department report found about half of troops had tried marijuana in Vietnam — that part is documented. But the claim that returning veterans drove domestic cultivation is folklore. Historians credit the back-to-the-land counterculture and the cutoff of Mexican imports; the veteran story lives mostly in strain-shop lore.
For every myth, there’s a fact that sounds made up — but isn’t.
Herodotus (c. 440 BCE) described Scythians throwing cannabis on hot stones inside sealed tents and “howling with joy.” In 2019, archaeologists found 2,500-year-old braziers in western China with charred stones bearing chemical traces of THC — the earliest hard evidence of people smoking cannabis to get high.
Canvas descends, via the Latin cannabaceus (“made of hemp”), straight from cannabis — because canvas was literally hemp cloth, used for ships’ sails and rope. Same root, different spelling.
Around 1971–72, students at Stanford’s AI Lab used their ARPANET account to arrange a small marijuana sale to counterparts at MIT — documented by tech journalist John Markoff. No money moved electronically, so it’s the first online deal, not the first online payment.
In 1988 the DEA’s own chief administrative law judge, Francis Young, ruled that “marijuana, in its natural form, is one of the safest therapeutically active substances known to man,” and recommended rescheduling. The DEA administrator overruled him, and cannabis stayed Schedule I.
The 0.3% THC threshold that legally separates “hemp” from “marijuana” comes from a 1976 botany paper by Ernest Small, who called it an admittedly arbitrary guide — not a measure of what gets you high. It was later written into the 2018 Farm Bill, and now defines a multibillion-dollar industry.
