Opium

• 1. Introduction

  ›

  Opium is the dried latex drawn from the seed capsules of a single plant, Papaver somniferum. It is also known by a poetic Latin name: Lachryma papaveris, the tears of the poppy. That image is strangely apt. To harvest the drug, a farmer scores the immature pod by hand, and the plant weeps a milky white fluid that dries to a sticky yellowish residue overnight. The method has not changed in any meaningful way since the Sumerians of Mesopotamia first cultivated the poppy around 3400 BCE and called it hul gil, the joy plant.

  Approximately 12 percent of opium is made up of morphine, the alkaloid at the heart of modern pain relief. From that single chemical, chemists have derived heroin, oxycodone, hydrocodone, and a long chain of synthetic successors. The latex also contains codeine and thebaine, alongside non-analgesic compounds like papaverine and noscapine. One plant, one dried residue, and the modern opioid crisis, two centuries of colonial conflict, the world pharmaceutical industry, and the poppy fields of Afghanistan all trace back to it.

  How did a medicinal crop from ancient Mesopotamia become the center of wars, empires, and a global drug trade? The answer moves through Minoan Crete, the courts of Chinese emperors, the counting houses of the British East India Company, and the poppy fields of Helmand Province.

• 2. The Ancient World

  ›

  At least 17 finds of Papaver somniferum have been reported in Neolithic settlements across Switzerland, Germany, and Spain. Among the most remarkable is the Cueva de los Murciélagos, or Bat Cave, in Spain, where large numbers of poppy seed capsules were placed at a burial site carbon-14 dated to 4200 BCE. That placement suggests a ritual significance almost as old as settled human culture.

  Tablets found at Nippur, a Sumerian spiritual center south of Baghdad, described collecting poppy juice in the morning for use in producing opium. The Assyrians continued the practice, calling the juice aratpa-pal, a word that may be the root of the Latin Papaver. By around 1300 BCE, the Egyptians were cultivating what they called opium thebaicum in famous poppy fields and trading it through Phoenician and Minoan merchants to Greece, Carthage, and Europe. On Cyprus by 1100 BCE, surgical-quality knives were in use for scoring the pods.

  A figurine from that same Minoan period, dated to around 1300 BCE, shows a goddess whose hairpins are shaped as poppy capsules, each bearing slits consistent with the scoring technique. Her expression, slightly parted lips and a distant gaze, led scholars to call her the goddess of ecstasy. The Greek gods Hypnos, Nyx, and Thanatos were all depicted wreathed in poppies. Statues of Apollo, Asclepius, Demeter, and Isis bore the same symbol, linking the flower permanently to sleep, night, and death.

  Ancient writers disagreed about how the drug should be used. Hippocrates saw opium as a natural remedy best used sparingly. Diagoras of Melos and Erasistratus argued addiction would harm brain and body and urged abstinence entirely. The third-century BCE writer Theophrastus described the technique of obtaining sap by crushing the plant; the older method of incising the pod had been lost by his era and was not relearned until 40 CE, when Scribonius Largus, physician to the Emperor Claudius, wrote out the process again.

• 3. Islamic Medicine and Transmission

  ›

  Between 400 and 1200 CE, Arab traders carried opium into China, and by 700 CE into India. The movement of the drug tracked the expansion of Islamic civilization and trade, and within that civilization opium found some of its most systematic medical thinkers.

  Muhammad ibn Zakariya al-Razi, known in the West as Rhazes, lived from 845 to 930 CE and ran a laboratory and school in Baghdad. He had studied and criticized Galen, and he used opium as an anesthetic. In his home medical manual Fi ma-la-yahdara al-tabib, meaning roughly In the Absence of a Doctor, he recommended opium for the treatment of melancholy, a text aimed at ordinary citizens who lacked access to a physician.

  The Andalusian surgeon Abu al-Qasim al-Zahrawi, known as Abulcasis, lived from 936 to 1013 CE and relied on opium and mandrake together as surgical anesthetics. His treatise al-Tasrif shaped medical thinking well into the 16th century. Most influential of all was the Canon of Medicine by the Persian physician Avicenna. He listed opium's clinical effects with unusual precision: analgesia, hypnosis, cough suppression, gastrointestinal action, respiratory depression, and sexual dysfunction. He described multiple methods of delivery and recommended doses, and he noted its potential as a poison. The Canon was translated into Latin in 1175 and remained authoritative into the 19th century.

  The five-volume De Materia Medica by Dioscorides, which described opium extensively, stayed in continuous use from the 1st to the 16th century, with Arabic translators editing and improving the text. By the 14th century, the Ottoman physician Serafeddin Sabuncuoglu was prescribing opium for migraine headaches, sciatica, and other painful ailments, part of an unbroken thread of medical use stretching back to Nippur.

• 4. Paracelsus and Western Revival

  ›

  Paracelsus reintroduced opium to Western medicine in 1527, arriving in the European intellectual world with a dramatic flair. He claimed to have returned from wanderings in Arabia carrying a famous sword, inside whose pommel he kept what he called Stones of Immortality, compounded from opium thebaicum, citrus juice, and quintessence of gold. The claim was widely viewed as dubious even by his contemporaries.

  His personal name, Philippus Aureolus Theophrastus Bombastus von Hohenheim, was less famous than the pseudonym he chose: Paracelsus, meaning the equal or better of the Roman medical writer Aulus Cornelius Celsus. Three weeks after being appointed professor at the University of Basel, he burned the Canon of Medicine in a public bonfire, though he was burning a text that described the same opium-based medicine he was promoting. During his lifetime he was regarded as an adventurer who challenged the theories and mercenary motives of his colleagues with dangerous chemical therapies. That combativeness marked a genuine turning point in Western medical thinking.

  Laudanum, originally a 16th-century term for a widely admired medicine associated with a specific physician, became standardized as tincture of opium, a solution of opium in ethanol. Thomas Sydenham, the 17th-century physician called the father of English medicine or the English Hippocrates, recommended laudanum in the 1660s for pain, sleeplessness, and diarrhea. He is attributed the remark that among all remedies God has given man to relieve his sufferings, none is so universal and so efficacious as opium. By the 18th century, laudanum was readily available across England. Medical textbooks of the period recommended its use even by people in good health, to optimize the internal equilibrium of the human body.

• 5. China, the Opium Wars, and Prohibition

  ›

  The earliest clear Chinese record of recreational opium use comes from Xu Boling, who wrote in 1483 that opium was mainly used to aid masculinity, strengthen sperm, and regain vigor. He also described an expedition ordered by the Ming dynasty Chenghua Emperor that same year to procure opium for a price equal to that of gold. A century later, Li Shizhen included standard medical uses in his Compendium of Materia Medica of 1578, while noting that lay people used the drug for the art of sex.

  Opium smoking arrived in China partly on the heels of tobacco, and the Ming emperor's brief ban on tobacco smoking may have encouraged smokers to add opium to their pipes. Tobacco mixed with opium was called madak, and by 1712 the German physician Engelbert Kaempfer observed that no commodity across the Indies was retailed with greater profit than opium, which its users could not do without. When the Qing emperor banned madak in 1729 while initially exempting pure opium as a potentially medicinal product, the smoking of pure opium rose sharply. By 1861, even a small village without a rice store would have a shop where opium was sold.

  China's positive trade balance with Britain created pressure on British silver stocks. British merchants turned to opium, produced in India under the strict monopoly of the British East India Company, as a high-value commodity. Bengal opium commanded twice the price of domestic Chinese product. Smuggling rose from 200 chests per year under the Yongzheng Emperor to 30,000 under the Daoguang Emperor. Between 1814 and 1850, the trade sucked out 11 percent of China's money supply.

  In 1838, the Chinese Commissioner Lin Zexu destroyed approximately 2,660,000 pounds of opium in Guangzhou. Queen Victoria, unwilling to replace the cheap opium with costly silver, began the First Opium War in 1840. Britain won Hong Kong and a series of trade concessions under what became known as the Unequal Treaties. The future British Prime Minister William Ewart Gladstone, whose sister Helen had suffered from opium's effects, called the war more unjust in its origin, more calculated in its progress to cover the country with permanent disgrace, and said in May 1840 that he felt in dread of the judgments of God upon England for national iniquity towards China. His opposition to both Opium Wars was fierce and consistent.

  Following China's defeat in the Second Opium War in 1858, domestic production expanded rapidly. By 1906, China produced 85 percent of the world's opium, roughly 35,000 tons, with an estimated 13.5 million people consuming 39,000 tons yearly. Protestant missionaries gathered medical evidence of harm at the 1890 Shanghai Missionary Conference and established the Permanent Committee for the Promotion of Anti-Opium Societies. Benjamin Broomhall of the China Inland Mission lobbied the British Parliament and formed the Christian Union for the Severance of the British Empire with the Opium Traffic in 1888. An official Chinese anti-opium initiative launched on the 20th of September 1906 aimed to eliminate the problem within ten years; smokers were required to register for gradually reduced rations. The program made progress but unraveled after the death of Yuan Shikai in 1916, with opium farming peaking again in 1930 when the League of Nations identified China as the primary source of illicit opium in East and Southeast Asia.

• 6. From Morphine to Modern Opioids

  ›

  Friedrich Wilhelm Adam Sertürner first isolated morphine from the opium poppy in 1804. He published his results in 1817, after thirteen years of research and a near-disastrous self-experiment he conducted along with three boys. His work established a principle that would reshape medicine: a patient could now be treated with a known dose, rather than the unreliable concentrations of raw plant material. As the Renaissance anatomist Gabriel Fallopius had lamented centuries earlier, if soporifics are weak they do not help; if they are strong they are exceedingly dangerous.

  Morphine sales began in 1827 through Heinrich Emanuel Merck of Darmstadt, and the profits helped him expand his family pharmacy into what became the Merck KGaA pharmaceutical company. By 1820, isolations of noscapine, strychnine, caffeine, and quinine had also been reported, all inspired by Sertürner's method. Codeine was isolated in 1832 by Pierre Jean Robiquet. General anesthesia using diethyl ether and chloroform arrived in 1846-1847 and rapidly displaced opiates for surgical procedures.

  Heroin was first synthesized in 1874 but attracted no notice until Felix Hoffmann at the Bayer pharmaceutical company in Elberfeld rediscovered it in 1897. From 1898 to 1910, Bayer marketed heroin as a non-addictive morphine substitute and cough medicine for children, on the reasoning that its lethal dose was thought to be a hundred times greater than its effective dose. By 1902, heroin sales made up 5 percent of the company's profits, and media coverage of what was being called heroinism had begun. Bayer introduced oxycodone, a thebaine derivative, in 1916, again promoted as a less addictive analgesic. Methadone followed in 1937, pethidine in 1939, and fentanyl in the late 1950s.

  Morphine nonetheless retained its position at the center of battlefield medicine. American combat medics still carry syrettes containing 16 milligrams of morphine each, and no drug has been found that can match the painkilling effect of opioids without also duplicating much of their addictive potential.

• 7. Afghanistan and the Modern Trade

  ›

  Afghanistan became the world's dominant opium producer over decades of conflict, climate, and political collapse. In late 2004, a U.S. government estimate placed 206,000 hectares under poppy cultivation in the country, representing 4.5 percent of its total cropland. That year's estimated production of 4,200 metric tons accounted for 76 percent of world supply and yielded 60 percent of Afghanistan's gross domestic product. For farmers, the crop could be up to ten times more profitable than wheat.

  Solar panels became an unexpected factor in the expansion. As Afghan farmers gained access to solar energy to power deeper wells, water availability increased and with it the poppy harvest, producing bumper crops year after year. Under the Taliban's first period of control, production was cut dramatically, dropping to 74 tons per year under a ban issued in 2000, a reduction of 94 percent. When American and British forces removed the Taliban and installed an interim government in 2001, the land under cultivation leaped back to 285 square miles, and Afghanistan quickly surpassed Burma as the world's largest opium producer. By 2006, the UN Office on Drugs and Crime estimated production had risen 59 percent, with 407,000 acres under cultivation and 6,100 tons produced, representing 82 percent of world supply.

  A November 2023 UN report documented a different turn. Poppy cultivation across Afghanistan had dropped by over 95 percent under Taliban campaigns, including a 99 percent reduction in Helmand Province alone, removing Afghanistan from its position as the world's largest producer. In 2023, Burma overtook Afghanistan, producing 1,080 metric tons according to the UN Southeast Asia Opium Survey. The legal production side of the trade runs through a different set of institutions: Mallinckrodt, Noramco, Abbott Laboratories, Purdue Pharma, and Cody Laboratories process legal imports in the United States, while GlaxoSmithKline, Johnson and Johnson, and MacFarlan Smith operate legal production in Tasmania, and the World Health Organization has estimated that global medical production would need to increase fivefold to meet total medical need worldwide.
