The cocaine on British streets is stronger than it has ever been. Cocaine purity in the UK has more than doubled in just 13 years, and the consequences are showing up in the death toll. A record 1,279 people died from cocaine-related causes in England and Wales in 2024. That is a 14 per cent rise on the year before, and the thirteenth consecutive annual increase.

From Street Drug to Ultra-Strength Cocaine

Thirteen years ago, cocaine sold at street level contained between 32 and 38 per cent purity. Today that figure sits above 80 per cent in many cases. The drug has not changed. The supply chain has.

An undercover investigation at the Cheltenham Festival this year put that reality into sharp focus. The festival draws more than 200,000 visitors. Researchers collected samples from toilet surfaces and sent them to Kingston Analytical Services Toxicology (KAST) at Kingston University. Two out of three samples tested came back at 85 per cent purity. One came from a baby changing facility.

Dr Arija Durrant, a postdoctoral researcher who ran the tests, said the results pointed clearly to a higher overdose risk. Someone accustomed to 30 per cent cocaine taking the same amount of an 85 per cent batch could face fatal consequences without realising anything was different.

Professor Harry Sumnall of Liverpool John Moores University, who advises the government on drug policy, called anything above 85 per cent “ultra strength.” He added that high-purity cocaine had made the UK market more dangerous than at any previous point.

Cocaine Purity in the UK Fuelled by Record Global Supply

This rise in cocaine purity in the UK does not exist in a vacuum. Supply from South America is driving it.

The UN World Drug Report 2025 recorded more than 3,708 tonnes of cocaine produced globally in 2023. Expanded coca cultivation in Colombia accounts for much of that growth. More supply means lower wholesale prices and less need to dilute the product before selling it on.

Peter Cain, a drug science adviser at Eurofins Forensic Services, tracks purity levels in drugs seized by police forces. He said street-level purity reached around 75 per cent during the Covid pandemic and has climbed further since. “It’s a buyer’s market,” he said. “Users are getting a stronger product and paying less, at a time when everyone else is paying more for everything.”

The EU Drugs Agency reported last year that average cocaine purity across half its member states had risen to between 66 and 81 per cent. The UK sits at the higher end of that picture.

Supply Routes and the Scale of High-Purity Cocaine Reaching Britain

The UK held the largest cocaine consumer rate in Europe in 2023, according to the Organisation for Economic Cooperation and Development. Wastewater analysis in England showed consumption rose by a quarter over the five years to 2024. The market generates around £1.9 billion a year.

Cocaine enters the UK by air and sea through a growing range of routes. A report by Dame Carol Black found Albanian organised crime groups dominate importation. Eastern European supply channels have also expanded.

Border agencies have made significant interceptions. Officers seized around five tonnes of cocaine at a single port in under a month, cutting off more than £400 million worth of supply to criminal networks. In 2024, police caught five men smuggling 332kg of cocaine with 89 per cent purity, worth £26.5 million, via speedboat to the West Country coast.

Adam Thompson, head of drugs threat at the National Crime Agency, said production records in South America had pushed wholesale prices to historic lows. He acknowledged that without falling demand, supply enforcement alone would not solve the problem.

Lives Cut Short

Behind every figure is a person. Lucy White was studying criminology at the University of the West of England in Bristol. She died of a cardiac arrest caused by cocaine use. Her sister Stacey Jordan has since pushed for better drug education in schools and universities.

In 2024, Emily Rose Browning, a 24-year-old teacher from Cardiff, died of a cardiac arrest hours after taking cocaine on a night out. That same year, Lindsey Strickland, 41, died after a cardiac arrest following a night out with friends in Salford.

The NHS warns that cocaine can cause heart attacks, strokes and seizures. Mixing cocaine with alcohol raises the overdose risk further. As cocaine purity in the UK climbs to new highs, users have less room for error than ever before.

A Health Crisis That Demands a Proper Response

Mike Trace led drug policy under Sir Tony Blair and now runs the Forward Trust, a drug and alcohol support service. He called the current situation a “health scandal.” He said unpredictable potency makes high-purity cocaine especially dangerous.

“If somebody buys white powder off their dealer on a Friday night and they’re used to getting a certain hit off 30 per cent pure substance, but what they bought this Friday was 60 per cent, they’re in trouble,” he said.

Mr Trace wants the government to set up drug checking programmes in towns and cities so users can test what they are taking. That has not happened. Instead, government figures from the National Audit Office show a 40 per cent cut in real-terms spending on adult drug and alcohol treatment between 2015 and 2022. Hospital admissions for cocaine and crack cocaine use had already tripled in the decade to 2018.

Warrington North MP Charlotte Nicols warned in November that the Home Office was showing hostility towards solutions that did not involve further criminalisation.

What Needs to Change

The numbers tell a clear story. Cocaine purity in the UK has more than doubled. Deaths have risen every year for over a decade. Global supply keeps breaking records, and treatment services keep losing funding.

High-purity cocaine turns up not just in clubs but in family-friendly venues, as the Cheltenham findings show. This is a mainstream public health problem. Drug science researchers, health professionals and policy advisers broadly agree that the current response falls short.

Without real investment in treatment, education and harm reduction, the death toll will keep rising. The data leaves very little room for doubt.
