You are in Chapter 3: Smoke and Spirit: Cannabis in the Ancient World.
Professor High, a small time traveller in a long coat, watches cute fruit nomads crawl into a felt-covered tent heaped with hot stones on a windy steppe at dusk, while a wooden brazier smokes in the foreground.

The strongest early evidence that people used cannabis for its effects, not only for rope and food, dates from about 800 to 500 BCE. It comes from graves and shrines in western China, the Pamir Mountains, and Judah. The Siberian finds are weaker. The famous older stories do not survive a check. No emperor wrote a cannabis medicine book in 2737 BCE. No verse in Exodus names the plant for sure. The mummy tests that claimed cannabis in Egypt are in doubt.

This chapter covers 2000 BCE to 500 CE. Earlier chapters followed the plant as a crop: seeds, fiber, and cord (Chapter 2 tells that story). Around the 800s BCE, the record changes. Seeds sit beside burned stones. Chemists find THC breakdown products in charred wood. A Greek writer describes a steam bath that sounds like a party.

Three kinds of evidence carry the chapter. Plant remains show that cannabis was present. Chemical residues show that someone burned or ate it. Texts show what people said about it. No single kind proves a high, and a text can be wrong. So every placard below carries a confidence meter, and the myth cards say plainly what fails.

Who buried cannabis with the dead in western China?

Start with a tomb near Turpan, in Xinjiang. Excavators at the Yanghai Tombs found a man they call a shaman, judging by the ritual objects in his grave. Near his head and feet lay a leather basket and a wooden bowl filled with cannabis shoots, leaves, and seeds (Ren et al. 2019). Climate and burial conditions kept the plants in superb shape (Russo et al. 2008).

A team led by Hong-En Jiang dated the cache by radiocarbon and confirmed that the plant was cannabis. They assumed the plant served ritual or medical needs (Jiang et al. 2006). Two years later, Ethan Russo and colleagues ran chemical and DNA tests. They found THC, its breakdown product CBN, and the gene for the enzyme that makes THC. They called it the oldest documentation of cannabis as a pharmacologically active agent (Russo et al. 2008).

The two papers disagree on the tomb’s age. Jiang’s team says 2,500 years. Russo’s team says 2,700 years. Both numbers land between the 7th and 5th centuries BCE, so this chapter says “roughly 700 to 500 BCE.”

A man buried at Yanghai lay beside a basket and bowl of cannabis shoots, leaves, and seeds. Tests found THC and its breakdown product CBN. The authors judge the plant ritual or medical; the grave does not show how it was used.

The Yanghai cache as the excavators describe it: a leather basket and a wooden bowl of cannabis beside the dead man's head and feet.

The bowl matters. It shows wear from long use as a mortar, which suggests someone ground the cannabis before use. Nothing in the tomb shows that anyone burned or smoked it, so the plant may have been eaten or drunk (Ren et al. 2019). The grave proves that cannabis mattered to this man. It does not say how. In the same Turpan area, a grave at the Jiayi Cemetery held a burial shroud made of 13 dried cannabis plants. Ren’s team says new finds of ritual cannabis use in western China are well documented. The Jiayi shroud is one of them.

Now climb into the Pamir Mountains. At the Jirzankal Cemetery, mourners raised round mounds ringed with stones and laid long strips of black and white pebbles across the ground. In eight tombs, archaeologists found ten wooden braziers, each holding stones with clear burn marks. Three braziers were carved from juniper, a wood that gives off a sharp, turpentine-like perfume when it burns. The site was in use 2,400 to 2,600 years ago.

Meng Ren and colleagues scraped the charred crust from the braziers and ran gas chromatography–mass spectrometry. All but one of the inner surfaces carried the chemical signature of cannabinol (CBN). Heat, light, and air turn THC into CBN. The outer walls, used as a control, held no cannabinoids. The braziers also showed no sign of CBD, the non-intoxicating cannabinoid that wild plants usually carry beside THC. The team argues that the burned plants held more THC than typical wild cannabis. They suggest mourners laid cannabis on hot stones in the braziers, and that the smoke belonged to the burial rite itself (Ren et al. 2019).

Cannabis burned in wooden braziers at funerals

Ten wooden braziers from eight tombs held burned stones. Chemists found cannabinol, a THC breakdown product, on all but one inner surface and none outside. The team reads this as ritual cannabis smoking with high-THC plants.

One limit stays in place. No seeds, leaves, or flowers remained in any brazier. The plant is gone; only its chemistry survives. The step from “CBN” to “high-THC plants” is the authors’ inference, and one study is all we have so far.

What did Herodotus see on the steppe?

In the 5th century BCE, the Greek writer Herodotus wrote about the Scythians, horse nomads of the Eurasian steppe. He describes what they did after a burial. They cleansed themselves under a tent of mats stretched over three poles. Here is his account of the hemp, in A. D. Godley’s 1920 translation (Histories 4.75, Perseus Digital Library):

The Scythians then take the seed of this hemp and, crawling in under the mats, throw it on the red-hot stones, where it smoulders and sends forth such fumes that no Greek vapor-bath could surpass it. The Scythians howl in their joy at the vapor-bath.

Herodotus adds that hemp grows in Scythian country, “very like flax, except that the hemp is much thicker and taller,” and that the Thracians weave it into cloth that looks like linen (Histories 4.74). Classicist James Butrica notes that cannabis seems to have been largely unknown to Greeks in the 5th century BCE. Herodotus gives the earliest mention of it in Greek literature (Butrica 2002).

Herodotus describes the Scythian hemp vapor bath

Herodotus writes that Scythians threw hemp seed on red-hot stones under mats and howled with joy at the fumes. It is the earliest Greek mention of cannabis. The text names seed, which carries the least THC of any plant part.

Did the archaeology agree? In part, yes. In the late 1940s, Sergei Rudenko opened frozen burial mounds at Pazyryk, in the Altai Mountains. In barrow 2, his team found a small wooden tent frame, copper vessels holding burned stones and charred hemp seeds, and a leather pouch of cannabis seeds, coriander, and yellow sweet clover (Ren et al. 2019). Newer dating puts barrow 2 at 300 to 290 BCE, younger than Rudenko’s original dates (University of Washington Silk Road Seattle, on the Hermitage collection).

The match is close, but a puzzle remains. Seeds carry the least THC of any part of the plant, according to Ren and colleagues. The Jirzankal braziers held no seed at all. So what did the Scythians burn, and what did Herodotus hear about? Maybe they burned more than seed. Maybe a Greek writer got a detail wrong. The sources cannot settle it. Ren’s team also points out one difference: Herodotus puts the tent after the burial as a cleansing, while the Pamir smoke belonged to the burial itself.

On November 5, 2026, a new paper added a bold claim. Gino Caspari and colleagues report more than 1,000 cannabis seeds from the Tunnug 1 burial mound in the Uyuk Valley of Tuva, Siberia, dated to about 2,800 years ago. They also found compounds from the plant in human hair from the tomb. They call it the earliest direct evidence of cannabis use (Science, 2026).

Outside experts split. Volker Auwaerter, a forensic toxicologist at the University Medical Center Freiburg, calls the hair analysis “scientifically weak.” He says buried hair could pick up traces from cannabis lying beside it. Elisa Guerra Doce of the University of Valladolid says hair testing is not new in archaeology and has been used to identify drug use, and credits the authors for showing that cannabis was consumed, not only left as an offering (Associated Press). Treat Tunnug 1 as a promising lead, not a settled fact.

Did a shrine in Judah burn cannabis at Arad?

Move to the southern border of the kingdom of Judah, in today’s Israel. A fortress at Tel Arad held a small shrine. Yohanan Aharoni’s team uncovered it in the 1960s. At the door of its inner room lay two limestone altars, with a black crust on top. Tests in the late 1960s could not identify the crust (Science News, 2020).

In 2020, Eran Arie, Baruch Rosen, and Dvory Namdar tested the crust again with modern methods. The smaller altar, about 40 centimeters high, carried THC, CBD, and CBN. They found animal dung mixed in, which would let the cannabis burn at low heat. The larger altar, about 50 centimeters high, carried markers of frankincense and animal fat (Arie, Rosen, and Namdar 2020). The shrine dates to about 750 to 715 BCE (Taylor & Francis press release, reposted by ScienceDaily).

The authors suggest the cannabis was a deliberate psychoactive offering. Arie said it was the first time anyone had identified cannabis in the Ancient Near East. That is a suggestion about intent, not a measurement. Archaeobotanist Robert Spengler said it is unclear how people in the Middle East got potent plants, and that the discoveries “further complicate the early story of cannabis” (Science News, 2020). And the Arad find does not show that cannabis burned in Jerusalem’s Temple. It comes from one fortress shrine.

Texts from the same centuries are harder to read. Assyrian medical tablets list a plant called azallû. According to Scurlock and Andersen, azallû was cannabis, probably used as a medicine, apparently for depression (Crocq 2020, summarizing Scurlock and Andersen). In 1949, the Assyriologist R. Campbell Thompson had also judged that azallû meant hemp. He listed a second word, qunubu, under the same plant. It appears in a letter to the king’s mother from the late 8th or early 7th century BCE, beside myrrh, in connection with rites (Thompson 1949, full text). The mentions are short and hard to read.

A famous Bible puzzle sits near this find. Exodus 30:23 lists spices, including qěnēh bośem. The King James Version renders it “sweet calamus.” In 1936, the Polish anthropologist Sula Benet argued that the Hebrew words sound like “cannabis” and so name hemp (Russo 2007). The standard Hebrew lexicon of Brown, Driver, and Briggs reads the phrase as “calamus, aromatic reed” (BDB entry).

What do India and China record?

In India, the earliest clue is a prayer. The Atharvaveda is a Sanskrit collection of hymns and spells, among the later Vedic books. Britannica dates the Vedic texts to roughly the 15th to the 5th century BCE and calls the Atharvaveda a later compilation, so the hymn sits somewhere inside that span (Britannica). In hymn 11.6, verse 15, in William Dwight Whitney’s translation, the speaker names five kinds of plants:

The five kingdoms of plants, having Soma as their chief, we address; the darbha, hemp, barley, sáha—let them free us from distress.

(Atharva-Veda Samhita, Book 11, Hymn 6, Wikisource transcription of Whitney’s translation.) The Sanskrit word is bhaṅga. Later Sanskrit uses bhaṅgā for hemp and for the drink commonly called bhang (Monier-Williams dictionary entry). The verse does not describe a high. It lists hemp among plants that protect.

China brings the most famous legend. Shennong, the “Divine Farmer,” is said to have taught people farming and herbal medicine. Legends place him among the Three Sovereigns, around 2852 to 2070 BCE. The earliest text that links him to herbs is the Huainanzi, a book of the Han dynasty (Public Domain Review). A herb book carries his name, the Shennong Bencao Jing. The original is said to have listed 365 medicinals, and the surviving versions list fewer. Entries for hemp (ma fen) and hemp seed are among them. The ma fen entry warns that taking much of it “may make one behold ghosts and frenetically run about,” in Yang Shouzhong’s English translation (full text).

But the book is not ancient in the way the legend says. The physician Tao Hongjing (452 to 536 CE) wrote that the old lore was first written down in the later Han, about 200 CE. The historian Paul Unschuld adds that no one can prove an original book with that title ever existed. The original is lost. Later editors tried to recreate it, and they included material from earlier books (both points from the translator’s foreword, same link).

A second Chinese story credits the surgeon Hua Tuo (140 to 208 CE) with mafeisan, a wine-based anesthetic. The character ma means hemp, and it also appears in words about numbness, so some writers guess that cannabis was an ingredient (Crocq 2020). But the histories that tell the tale do not list the ingredients, and no recipe survives (Zhao et al. 2018).

In 2026, a study in Antiquity tested iron scissors and tweezers from the tomb of Xia Quan, a Ming-era physician born in 1348. The residue held aconitine, a toxin from monkshood plants. The study did not report cannabis (Smithsonian Magazine). Some coverage set that find beside the Hua Tuo story. The two men lived more than 1,100 years apart.

What did the Greeks and Romans make of the plant?

Here the surprise is how little they say about getting high. James Butrica surveyed every surviving Greek and Latin mention of medical cannabis. Medical use is not attested before the first century CE. He found no secure evidence that Romans used cannabis as medicine. Butrica counts the comic poet Ephippus (4th century BCE) among the early mentions of eating the seed. His fragment lists hemp seeds among after-dinner delicacies. It names food and gives no effect (fr. 13 Kock, as quoted by Gainsford 2020; see also Butrica 2002).

The Greek physician Dioscorides, working in the first century CE, lists two plants called kannabis. The cultivated one has bad-smelling leaves, long hollow stalks, and a round seed, and it twists into very strong rope. Of the seeds he writes, “Eaten in quantities these quench conception.” The juice of the green plant, he says, helps earache (quoted from the Osbaldeston and Wood translation). Editors suggest several plants for his second, “wild” kind, and not all of them are cannabis (Dioscorides, De Materia Medica).

Pliny the Elder (23 to 79 CE) knew hemp mostly as a rope plant. He calls it “remarkably useful for making ropes” and praises the hemp of Alabanda for hunting nets (Natural History 19.56). In Book 20 he says the juice of the seed removes worms from the ear, “though at the cost of producing head-ache.” The translators note that this chapter mostly describes a different plant, the hemp marsh-mallow, with facts about true hemp mixed in (Natural History 20.97).

Only Galen, in the second century CE, hints at an effect on the mind. In On the Effects of Foods 1.34 (Kühn 6.550), he writes that some people toast the seed with sweets eaten after dinner. A large amount taken in a short space, he says, “overcomes the head, filling it with a warm and drug-like vapour” (English translation quoted by Gainsford 2020). Among the three famous writers, that is the closest anyone comes to describing a party snack with a catch.

Egypt gets a short entry here because so many websites claim it. Some modern writers read the Egyptian plant name shemshemet as cannabis. We found no Egyptological source that settles the reading, so this chapter leaves it off the timeline. The mummy claim is easier to test.

The claim: “Egyptian mummies were found with cannabis.”

A German team reported nicotine, cocaine, and hashish in mummy tissue in 1992 and 1993. Cocaine comes only from American coca. A 2008 review argues the Munich results may reflect contamination and urges caution with analytic methods.

What does the ancient evidence add up to?

Put the best finds side by side and the pattern is clear. The strongest evidence sits in graves and shrines from about 800 to 500 BCE. It is physical. Most written sources say less about getting high than the internet claims.

Remember what this evidence cannot do. A burned stone does not show who enjoyed it. A medical text does not show that the remedy worked. This chapter reports what people did, not what helped them. For every claim that fails the test, see the full myths page.
