Nigeria’s Cough Syrup Crisis: The High That Would Not Die
In Nigeria, a bottle of cough syrup is never just a bottle of cough syrup. For more than a decade it has been a street drug, a family medicine, a black-market commodity, and, at its worst, a poison. The country is fighting two crises at once. One is the long, unfinished war against codeine and its replacements. The other is the quieter danger of contaminated and counterfeit syrups that can shut down a child’s kidneys. Together they explain why a product sold as relief keeps returning as a public-health emergency.
The first crisis became impossible to ignore in 2018. A BBC Africa Eye investigation, Sweet Sweet Codeine, showed how an ordinary cough suppressant had become a mass opioid. Young people mixed it with soda or alcohol and called it lean, purple, or gutter water. The Nigerian Senate estimated that about three million bottles were consumed every day in Kano and Jigawa alone. Codeine is an opiate. The body converts part of it into morphine. Taken in the volumes then common on the street, it produced euphoria, dependence, organ damage, and, in some cases, death.
NAFDAC moved fast. Over-the-counter sale, local manufacture, and importation of codeine-containing cough preparations were banned. Millions of bottles were recalled. Factories were shut. NDLEA units seized truckloads. For a moment it looked like a clean break. It was not.
The demand did not disappear. It went underground. Dealers stopped displaying bottles and sold from hidden stores or through night-time agents. Prices rose. In late August 2026, reporters in Zamfara, Jigawa, Kano, Lagos, and Kaduna found the same pattern: some shops still sold the banned syrup; others had pulled it from the shelf only to keep it in a back room. A bottle that once sold for a few hundred naira was going for ₦900 to ₦1,600. In Kano, a witness described two bottles changing hands for ₦14,000. Addicts who needed several bottles to get high could no longer afford the habit. Some switched to cannabis. Others simply paid more and bought in secret.
Enforcement numbers show why the trade survives. NDLEA still intercepts large consignments years after the ban: nearly 1,500 bottles from one Kano suspect in early 2026; more than 1.9 million bottles recovered from illegal Lagos warehouses in April; clandestine factories and port containers elsewhere. Officials admit the harder problem is stock already in circulation. Once the bottles leave a factory or a border post, they scatter into patent medicine shops, open markets, and private rooms. Recalling them is slow. Arresting every small seller is impossible. Porous borders keep new supply coming. Nigerian networks have even been reported buying codeine syrup in South Africa, where pharmacy rules are looser, and moving it home.
When codeine became scarce, users looked for the next bottle that could still deliver a high. The Ministry of Health had suggested dextromethorphan as a less addictive substitute. Pharmacists and psychiatrists say that advice underestimates the drug. Dextromethorphan, like diphenhydramine, is sold over the counter. In high doses it produces euphoria, dissociation, hallucinations, and, in extreme cases, coma. A 2025 survey of community pharmacists in Lagos, Ogun, Ondo, Rivers, and Abuja found that two-thirds saw young people buying these syrups in bulk every week or month. Diphenhydramine products led the list. Almost none of the pharmacists reported the abuse to NAFDAC. Existing law treats the products as ordinary cough medicine. Refusing a sale is legally awkward and commercially costly. Ban one molecule and the market finds another. That is the lesson of the “new bride,” as one newspaper called dextromethorphan.
The second crisis is older and deadlier in a different way. Diethylene glycol and ethylene glycol are cheap industrial solvents. Unscrupulous suppliers sometimes pass them off as pharmaceutical-grade glycerin or propylene glycol, the thickeners used in syrups. The chemicals destroy kidneys. Children die quickly.
Nigeria has already paid that price. In 1990, DEG-tainted paracetamol syrup killed at least 47 children in Jos. In 2008 and 2009, a teething mixture called My Pikin killed about 84 children. NAFDAC shut the manufacturer and pulled bottles from shelves. In 2022, WHO linked four Indian-made paediatric syrups to dozens of child deaths in The Gambia. NAFDAC warned importers and the public. In 2024, laboratory tests in Nigeria found unacceptable DEG levels in a batch of Benylin Paediatric Syrup made in South Africa. The product was recalled in Nigeria and several other African countries. Officials said they had no confirmed child deaths from that batch. The scare was enough. The same toxin family has killed hundreds of children across Gambia, Indonesia, Uzbekistan, and Cameroon since 2022.
These two stories meet in the informal market. NAFDAC has estimated that more than 30 percent of medicines sold in open-air stalls and roadside shops are counterfeit or substandard. Most Nigerians still buy there, not in licensed pharmacies. Raids keep turning up banned codeine syrups beside fake antimalarials, tramadol, and unregistered products. One Lagos warehouse seizure was described by investigators as large enough to kill millions if the stock had reached the street. Bonfires of confiscated drugs have become a regular public ritual. They look decisive. They do not close the market that replaces what was burned.
The official response is familiar: alerts, prescription-only rules, enlightenment campaigns, joint operations by NAFDAC, NDLEA, Customs, and the Pharmacists Council. Those tools matter. They do not reach the causes that keep the bottles moving. Unemployment and idle youth create customers. Open drug markets create distribution. Weak border control creates supply. Pharmacists have little legal cover to refuse OTC sales. Rehabilitation centres are scarce; in some states, officers say they can only counsel the people they arrest. Parents often will not cooperate. A ban that hits licensed manufacturers while leaving the black market untouched simply transfers profit from factories that can be inspected to dealers who cannot.
There is a practical way to buy a cough medicine in Nigeria and a dangerous way. The practical way is a sealed, registered product from a licensed pharmacy, used at the stated dose, and only when a cough actually needs a suppressant. Many childhood coughs do not. The dangerous way is an unlabelled bottle from a stall, a “strong mixture” poured from a jerry can, or three bottles of whatever still gets you high. The difference is a NAFDAC number, an expiry date, and a pharmacist who is allowed to say no.
Nigeria does not lack laws. It lacks a closed supply chain. Until high-risk syrups are pulled out of open markets, until borders and informal shops are treated as seriously as factory licences, and until prevention and treatment get the same energy as raids, the cough syrup crisis will keep changing its name. Codeine yesterday. Dextromethorphan today. A cheap solvent in a child’s bottle tomorrow. The bottle stays on the shelf. Only the poison inside it changes.
