Wars were fought for land, for succession, and for a woman who was said to have launched a thousand ships toward Troy. Opium fought its own war twice, in 1839 and again in 1856, but not the kind the name suggests.
Britain fought the war for the right to continue selling opium to China, after the Qing government attempted to ban it and began burning British stockpiles in the port of Canton. China lost both wars, and lost control of its opium market for the next century.Afghanistan has just tried to fight the same battle, but in reverse. In April 2022, Mullah Haibatullah Akhundzada announced a religious decree banning the cultivation of opium poppies across the country. It is not a foreign power that is forcefully introducing the drug, but the government in power trying to push it out of an economy that has been dependent on it for decades.
After the decree was issued, opium poppy cultivation declined by 95 percent by 2023, from 233,000 hectares in 2022 to nearly 10,800 hectares, according to the annual opium survey conducted by the United Nations Office on Drugs and Crime. Afghanistan produced between 80 and 90 percent of the world’s opium before the ban, and it is estimated that 95 percent of the heroin sold in Europe.This collapse in agriculture has been widely reported. What has been largely unreported is that it has not produced anything resembling a corresponding collapse in heroin availability.
To understand why, we need to look at how the ban was actually designed.The most detailed account of this comes from a May 2025 technical report commissioned by the European Union Drugs Agency (EUDA), written by David Mansfield, a researcher who has tracked Afghanistan’s drug economy longer than almost anyone else, and who works with the satellite imagery company Alsis.
Ban timing
The Taliban announced the ban roughly two weeks before the poppy harvest in 2022, giving farmers a two-month “grace period” to bring in the crop that had already been planted the previous fall.
The result was that 2022 would be the third largest opium crop ever, even with the announcement of the ban.
Key events in the Afghan opium ban
Then opium prices rose sharply: from about $60 to $75 per kilogram before the Taliban took over the country to roughly $1,000 to $1,035 per kilogram by December 2023, according to Mansfield’s field pricing data, nearly fifteen times as much.Since the ban was announced before the harvest rather than immediately after, and because opium was easy to store and did not spoil, farmers with land and the ability to hold stocks had every incentive to withhold their crops rather than sell them.
They anticipated the price rise that followed, and prepared to take advantage of it.The Taliban imposed its first opium ban in 2000-2001, which was announced three months into that year’s harvest, when opium was selling for about $30 a kilogram and most farmers had no surplus to suppress. This previous ban caused real, almost immediate shock to the show. This did not happen.
Where is the missing heroin?
Based on satellite maps of land sizes and productivity in former desert regions of southern and southwestern Afghanistan, reports suggest that farmers there alone may have opium stocks of more than 13,700 tons between 2019 and 2022.
Add to this reasonable retention by farmers in traditional surface irrigated areas, and the total potential stock rises to about 16,550 tons.This is the largest and best-documented estimate of Afghan opium stocks to date, and is significantly higher than UNODC’s assumption that most of each year’s crop is sold within twelve months.This is one of the main reasons why the open opium and heroin trade continues within Afghanistan, why seizures of opiates on Afghanistan’s borders with Pakistan, Iran and Tajikistan continue largely unabated, and why there is no evidence of a heroin shortage in Europe until late 2025.Almost all media coverage of the ban treats it as a single national policy with a single outcome. The data doesn’t support that. In the northeastern province of Badakhshan, a former Northern Alliance stronghold where Taliban authority was always relatively weak, poppy cultivation continued throughout two years of the ban.When regional authorities attempted a more aggressive eradication campaign in the spring of 2024, it sparked armed resistance from local communities.
Authorities subsequently scaled back law enforcement and delayed crop destruction until after harvest, rather than risk wider unrest in a province they did not fully control.
The real danger is not deficiency
The most important mechanism for consumers outside Afghanistan is not drying up supplies. This is what happens to the producer as the opium becomes more expensive to convert.Profitability in the sale of opium now depends on using stock purchased before prices rise, improving conversion efficiency, or – increasingly – adulterating the final product.
Opium adulteration
This adulteration is now well documented in regional markets: heroin sold in southwestern Afghanistan is marketed under names such as “Indian” (higher purity) and “Iranian” (lower purity, selling for a third to half the price), and heroin hydrochloride in Badakhshan is sold openly in graded batches of 40, 60 or 80 percent purity. Dealers are reportedly ordering specific mixtures of caffeine, paracetamol and unknown powders – called local MasalaOr “spice” – to collect cheap products.Heroin destined for European markets has been reported to be unadulterated and relatively high in purity, with European buyers paying a premium for it. But the EUDA report points to early signs of declining heroin purity in Europe through 2024, and clearly states that continuous monitoring of purity there is essential, because the same economic pressure that drives adulteration in regional markets applies, in principle, to the export product as well.If this pressure eventually reaches heroin bound for Europe, the precedent for the first Taliban ban is not encouraging. After prohibition in 2000-2001 led to a real heroin shortage, fentanyl almost completely replaced heroin in Estonia within about a year, and Estonia continued to have the highest per capita death rate from overdose in Europe for more than a decade thereafter.
Nitazine: the real danger
The substance most often mentioned in this context is not fentanyl, but a lesser-known class called nitazine, and why it has been the focus of official warnings is worth identifying specifically.Nitazine was first synthesized in the 1950s by researchers at the Swiss pharmaceutical company CIBA, who were studying pain relievers containing benzimidazole. These compounds were shelved and never brought to market: some of their analogues proved so effective that Swiss toxicological tests of the time found that doses as low as 1 mg per kilogram of body weight could be lethal, and the margin between the effective dose and the lethal dose was judged too narrow for clinical use.That changed after 2019. China gradually tightened controls on fentanyl and its analogues between 2016 and 2019, and China’s underground chemists responded, according to Wall Street Journal reporting and EMA analysis, by mining old, unscheduled pharmaceutical research for viable alternatives — and they settled on nitazine specifically because the class was robust, easy to synthesize, and not yet subject to any specific ban.The United Nations Early Warning System tracked the findings: By early 2025, UNODC reported 26 different nitazine analogues identified in 30 countries spanning Europe, North America, Oceania, South America and Southeast Asia.
Nitazine effectiveness chart
Efficacy estimates vary by analog, but a comparative measure was published in a 2025 clinical review in the journal Missouri Medicine Taking heroin as a baseline, fentanyl and one of the common nitazines (metonitazine) are both approximately 50 times as potent as heroin, another (protonitazine) is about 100 times as potent, and the two most dangerous street forms — isotonitazine and itonitazine — are approximately 250 and 500 times as potent as heroin, respectively.This scale is what makes even a small, accidental dose dangerous when nitazine shows up in something the user thinks is a Xanax pill or a bag of cocaine.The UK’s National Crime Agency has linked at least 333 deaths to nitazine in 2024 alone, and more than 400 deaths in Britain between June 2023 and January 2025 – although the agency itself suggests that gaps in routine toxicology testing likely mean this figure is an undercount. A separate US surveillance system in Tennessee found that deaths linked to nitazine overdoses nearly quadrupled between 2020 and 2021 alone.The EU drug agency has tracked detections of nitazine in at least 21 member states since 2019, with reported deaths concentrated in the Baltic and Nordic countries, along with France, Germany, Ireland and the UK. In September 2024, the EUDA Administrator issued a formal call to EU member states to act, warning explicitly against complacency: without the clear high-mortality crisis that the United States has seen with fentanyl, governments have limited political incentive to prepare, even as the underlying risks grow.Two features of how nitazine reaches users are important for the “consumption” question specifically, rather than the supply question. First, unlike heroin, nitazine is often found as an undeclared contaminant in other drugs – there have been cases where the drug has been found in e-cigarettes and nasal sprays, meaning many of those affected did not know they were taking opioids at all.Second, because the dose required is so small, distribution can bypass the multi-layered trafficking networks that transport heroin and cocaine.
Analysis by the Global Transnational Organized Crime Initiative indicates that Chinese suppliers were found to be marketing nitazine directly to European buyers through online B2B platforms and encrypted messaging apps, with the product mailed in small parcels rather than transported via established smuggling routes.
This direct-to-consumer channel is structurally different from anything the Afghan opium trade relies on, which is one reason why analysts argue that even a complete dissolution of Afghanistan’s opium economy will not eliminate this particular risk.
the Trojan horse
The claim that opium cultivation in Afghanistan has declined by 95 percent is accurate and well-sourced. The claim that this represents a 95 percent collapse in the global supply of heroin is not supported by the same evidence.What the evidence supports is a shocking truth: the heroin trade is slowly turning toward adulteration as the economics of diversion cease to work. None of this is considered a deficiency. It’s a market that absorbs the shock by changing what it sells and to whom, while the key statistics everyone quotes only describe the first link in a much longer chain.The Greeks did not need to storm the walls of Troy. They just needed the city to let the horse in and assume the war was over. Much the same went for the Taliban embargo, an edict that from the outside looked like the end of Afghanistan’s opium economy, slipped through the doors of global attention while the actual supply chain, the stockpiles, and the slow drift toward adulteration remained quietly moving inside. The 95 percent statistic is just a wooden horse.
What’s still inside has yet to be counted.
