Between 500 and 1800, cannabis lived two lives at once. As hashish, it moved through Muslim cities, Sufi lodges, and the Ethiopian highlands, while judges argued for centuries over whether it was a sin. As hemp, it became the rope, sail, and caulking of every navy, and kings ordered farmers to grow it. The popular tale of “hashish assassins” who killed for a drug is a myth, and it began as an insult.

This chapter follows both lives. They rarely met. A sailor on a hemp line and a Cairo poet praising “the green one” never compared notes. But they used one plant. For the story of the resin itself, from hand-rubbed charas to rosin, read our global history of hash. Here we follow where the plant went and what people said about it.

How did hashish enter the Muslim world?

Late, and with no verse to stop it. The Qur’an bans wine. It does not name cannabis. The physician Gabriel Nahas drew on the Arabic sources, mostly through Franz Rosenthal’s 1971 collection, in a 1982 review. Following Rosenthal, he says people first used hashish as an intoxicant in the late 800s, among religious sects on the eastern edge of the caliphate. They called it hashish, Arabic for “grass,” not the Hindu word bhang.

Late 800s, Eastern edge of the caliphate (Persia and Iraq)

Hashish surfaces as an intoxicant in the Muslim world

Citing Rosenthal, Nahas reports that hashish first appears as an intoxicant in the late 800s among Persian and Iraqi sects on the caliphate's eastern edge. The Qur'an bans wine but does not name cannabis.

The gap in the Qur’an mattered. Around the year 1000, the Fatimid caliph al-Hakim banned alcohol sales across Syria and Egypt, and he left cannabis alone. Many Muslims decided that a drug the Prophet never mentioned was not a sin.

Sufis, the mystical branch of Islam, enter the story in the 1100s. Arabic historians say one faction used hashish and carried it to Syria and Egypt. Nahas adds a warning: the great Sufi saints rejected drugs, and the hashish users were a deviant fringe. One legend credits a sheikh named Haydar, who lived in a mountain monastery around 1200. Walking in the midday heat, he found a plant that eased hunger and thirst and gave joy. Nahas calls the tale apocryphal. Even so, a Syrian poet wrote in 1292: “Give up wine and drink from the wine of Haydar.”

By the mid-1200s hashish was cheap and easy to hide. A Syrian poet wrote: “Tucked in a handkerchief it can be carried. No cup is needed if you wish to use it.” He added: “Hashish involves no sin. You are not punished.”

Rulers disagreed. Before 1250, the governor of Cairo ordered every cannabis plant in the Kafur garden uprooted. Police burned them in huge bonfires. A poet had written that the green plant of that garden “replaces in our hearts the effects of wine, old and generous.” Within a short time, farmers on the city’s outskirts were growing it again.

In 1266, the Mamluk sultan Baybars went further. Nahas says he banned both growing and using hashish. His men burned fields and closed taverns and brothels. Nahas thinks Baybars worried most about his soldiers, who were fighting the Mongols. A judge praised him: “The devil has no desire to stay with us! You have prevented him from obtaining both wine and hashish.” His successor taxed hashish and wine instead, then reversed course when use rose.

Did the Assassins really take hashish?

No. The story grew from an insult. The Nizari Ismailis, a branch of Shi’a Islam, founded a mountain-fortress state in Persia in 1090, and by the early 1100s their Syrian branch was meeting the Crusaders. Other Muslims called them hashishiyya. Farhad Daftary of the Institute of Ismaili Studies says the word was abuse, meaning “low-class rabble” or “people of lax morality.” It carried no claim about drugs. Nahas notes that Arabic texts used the word by 1125.

By 1125, Syria and Egypt (Arabic texts)

'Hashishiyya' is used as an insult for the Nizari Ismailis

Arabic texts used 'hashishiyya' for the Nizari Ismailis by 1125. Other Muslims meant abuse, 'low-class rabble,' with no claim about drugs. Crusaders later turned the insult into the word assassin.

Crusaders heard the insult in Syria and kept it. Their legends grew in stages from the time of the Syrian leader Rashid al-Din Sinan (1163 to 1193) through the 1200s. They explained the fighters’ courage with a drug. Daftary writes: “There is no evidence that suggests that hashish or any other drug was used in any systematic fashion to motivate the fida’is.” Hostile Muslim writers, he adds, “remain silent on this subject.”

Marco Polo gave the legend its famous shape. He added a secret “garden of paradise” where recruits supposedly received part of their training. Tradition says Polo dictated his book in a Genoese prison after his capture in 1296, according to the Library of Congress. Nahas points out that Polo names no drug at all. By the 1300s, Europeans and Crusader settlers accepted the tale as fact. The insult became the English word assassin.

Was hashish forbidden in Islam?

Jurists split, and the split lasted centuries. Most Muslim scholars read the ban on wine as a ban on anything that clouds the mind. Nahas says three of the four Sunni schools of law called hashish an intoxicant. The Hanafi school used a narrower definition.

Two thinkers show the range. The Maliki jurist al-Qarafi (died 1285) argued that hashish is mufsid, “corrupting,” but not an intoxicant like wine. In his view, users faced discretionary penalties, not the fixed punishment for drinking wine. Ibn Taymiyya (died 1328) took the hardest line. He said the analogy to wine is total, so hashish carries the same ban whether or not a dose intoxicates. He also blamed the Mongol invasions for its spread, a claim Nahas finds weak, since use came before the Mongols.

Al-Qarafi calls hashish corrupting, not intoxicating

The Maliki jurist al-Qarafi argued that hashish is mufsid, corrupting, but not an intoxicant like wine. Other jurists disagreed, so the law stayed unsettled for centuries.

The jurists won the argument and lost the street. Nahas writes that the belief that the Prophet banned only alcohol “became ingrained among the people.” Crackdowns came and went. Nahas lists Cairo bans or seizures in 1324 and 1394. Popular lists also credit an emir called Sheikouni with a famous purge in 1378. Nahas, citing the chronicler al-Maqrizi, dates it to 1376, and we have not read the chronicle ourselves. Treat the exact year and the details as unconfirmed.

Where were people smoking cannabis?

In Africa, earlier than most histories admit, though the dates are shaky. Medieval Arabic sources mostly describe hashish as something people ate. Nahas describes tobacco and hashish smoked together in the water pipe once tobacco reached the Ottoman world, around 1600.

Ethiopia tells a different story. In 1971, a Boston University student named J. C. Dombrowski dug in two Ethiopian caves and found eleven pipe bowls or fragments. One looked like a stone drinking cup until his team saw burn marks inside and a tiny hole in the base. It was a bowl for a water pipe. The chemist Nikolaas van der Merwe tested residue from two bowls from Lalibela Cave. This is a cave in Begemder Province (site approximate), not the rock-hewn churches of Lalibela town. Thin-layer chromatography found compounds from cannabis. Smoking heat turns short-lived cannabis compounds into long-lived ones, which chemists can still detect centuries later. Charcoal from the bottom of the same level gave a radiocarbon date of 1320, plus or minus 80 years.

Here is the catch. The date belongs to the level, not to the pipes, and most pipes lay above the charcoal. The historian John Edward Philips reviewed the African pipe finds in 1983. He called Lalibela the “earliest good evidence of cannabis smoking in Africa,” yet he warned there was “no direct correlation between the date and the pipes, and the connexion is conjectural.” Read our history of the bong for the water-pipe side of this find.

The geographer Chris Duvall argues that cannabis reached Africa from South Asia about 1,000 years ago and spread fast. He says African smoking cultures, which already existed, turned the plant into a fast-acting drug that was easy to dose. A reviewer adds that Duvall suggests the water pipe first developed in eastern and southern Africa. The written record south of the Sahara stays thin.

Southern Africa shows how careful you must be with a word. The Dutch founded Cape Town in 1652. In Jan van Riebeeck’s journal, the Khoikhoi use “the valuable herb dacha.” South Africans now call cannabis dagga. Yet the historian Simon Pooley writes that the plant was “most likely Wild dagga, Leonotis leonurus, not cannabis.” A word that looks like cannabis can name a different plant.

In India, a Portuguese doctor wrote down what he saw. Garcia de Orta published his Colloquies on the Simples and Drugs of India at Goa on April 10, 1563. The eighth colloquy covers “Bangue.” He says people ate the seeds or pounded leaves, and made a confection called majum. He quotes Sultan Bahadur, who told Martim Afonso de Sousa that “when, at night, he wanted to go to Portugal, Brazil, Turkey, Arabia, or Persia, he only had to take a little Bangue.” In the 1913 English translation, Orta adds a polite step back: “I have not tried it, nor do I wish to do so.”

Why did every navy need hemp?

Because every ship ran on rope. Forget the drug for a moment and picture a sailing ship. Every sizable vessel needed lines and sailcloth that could take a storm, and hemp proved the best fit, says Colonial Williamsburg’s study of colonial hemp. One small vessel in the Virginia Navy, the brigantine Liberty, needed more than two miles of cordage. Even the seams used hemp. Merriam-Webster defines oakum as loosely twisted hemp or jute fiber, soaked in tar, “used in caulking seams and packing joints.”

A sail loft: heavy hemp canvas, stitched by hand. The word canvas comes from the Latin word for hemp.

Rope needs farms, so governments gave orders. In 1533, Parliament passed An Act concerning sowing of Flax and Hemp, which told farmers to sow flax and hemp. A standard history says Tudor law also required a quarter acre of flax or hemp for every sixty acres of other crops. Colonial Williamsburg says the rising English navy was the main reason farmers, and later colonists, had to set land aside for hemp. One historian estimates that the fleet that faced the Spanish Armada in 1588 used the hemp of 10,000 acres. That figure is an estimate, not a count.

Spain made the same move. In June 1545, the Crown first ordered its subjects to sow cannabis in the New World, writes the historian Isaac Campos, who cites the Indies law code. Spaniards called the plant cáñamo. Its fibers made “clothing, rope, and the broad and sturdy sails that powered the greatest sea-borne empire the world had ever known.”

Britain could not grow enough. By the 1600s, Russia, Latvia, and other Baltic lands were the major hemp producers, and Britain bought from them. In wartime, the English struggled to buy enough, says Mount Vernon’s history of the crop. Colonial Williamsburg adds that Russian hemp beat the rest in both quantity and quality.

Europe’s other cannabis story is a myth. A claim that circulates online says Pope Innocent VIII declared cannabis an “unholy sacrament” in 1484. The bull is real. Summis desiderantes affectibus, dated December 5, 1484, targets witchcraft in parts of upper Germany. Its full text, in the Fordham sourcebook, names no plant. The closest it comes is a complaint that witches ruin “the grapes of vines, and the fruits of trees.”

Why did American colonies grow hemp?

For the same reason England did: ropes and sails. On August 2 to 4, 1619, Virginia’s first General Assembly met and passed its first laws. They told colonists to plant mulberry trees and vines. On hemp, the text reads: “For hemp also, both English and Indian, and for English flax and aniseeds, we do require and enjoin all householders of this colony, that have any of those seeds, to make trial thereof the next season.” That is a trial order for people who held seed, not a farm quota. Colonial Williamsburg notes that “Indian hemp” is also the name of a native plant, Apocynum cannabinum, which is not cannabis, so the phrase is unclear. A 1632 law went further: “every planter as soone as he may, provide seede of flaxe and hempe and sowe the same.” Virginians were later allowed to pay taxes in hemp. By the mid-1700s, Virginia had 12,000 acres of hemp against 45,000 of tobacco.

The founders grew hemp too. Mount Vernon says Washington’s diaries and farm reports put hemp on all five of his farms. It made rope, thread, canvas, and repairs for the big fishing seines. In the 1760s he weighed hemp as a cash crop to replace tobacco, then chose wheat. At Poplar Forest in 1811, Jefferson ordered that “an acre of the best ground” be kept “for a permanent hemp patch.”

Ask who did the work. Monticello’s records say enslaved laborers grew hemp at Monticello and Poplar Forest. The 1815 farm book lists three hemp spinners in the Monticello textile shop: Aggy, Nanny, and Isabel. Jefferson complained that breaking hemp by hand was “so slow, so laborious, and so much complained of by our laborers.” He then rigged a hemp break to his sawmill and later to a threshing machine.

None of this was about getting high. Colonial Williamsburg says no 18th-century American source mentions using hemp that way. Dense planting makes tall plants with few flowers. Even Washington’s famous hemp complaint was a farm complaint.

One last myth belongs here. Some sites claim the Declaration of Independence was written on hemp paper. Monticello’s answer: “As far as we know, this is not true.” The signed copy is on parchment, which is animal skin. Jefferson’s rough draft is on paper that Library of Congress conservators think was probably Dutch, and Dutch makers more often used flax or linen rags.

How did cannabis cross the Atlantic?

With people who did not choose the voyage. Portuguese ships carried enslaved Africans, some of them from Angola, across the Atlantic to Brazil. Duvall shows that people on those ships took their knowledge of smoking cannabis with them. A reviewer of his book notes that Portuguese slavers allowed use “to support the strength and condition of slaves.”

In Brazil the plant got names that record where it came from. One was fumo de Angola, “Angola smoke.” Others were fumo de negro and pito do pango. The Brazilian scholars Barros and Peres call the first name proof that the habit came from Africa with the enslaved. The names tied the plant to Black and enslaved people, and the law followed. In 1830, the city council of Rio de Janeiro banned the sale and use of pito do pango. As later authors quote the rule, the seller paid a fine, while slaves and other users got three days in jail. A 2026 study dates Brazil’s criminalization of cannabis to that year and ties it to policing aimed at racialized people.

By 1800, cannabis had two reputations. Rope makers and kings valued it as a crop that built empires. Cairo’s jurists and poets argued about it as a drug. Both stories were about to collide. In 1798, a French army landed in Egypt, and the modern West met hashish at close range. Chapter 5, The Medicine Cabinet, picks up there.
