The UK’s Most Violent Drug Model and Why It Matters

The Home Office describes County Lines as “the most violent model of drug supply” operating in the United Kingdom today. It is a tag that carries enormous weight. According to the first-ever national study of how British police forces respond to it, however, this label only begins to capture the reality on the ground.

County Lines is a specific distribution model, predominantly for heroin and crack cocaine. Organised crime groups and smaller independent dealers from major cities push their operations into smaller towns, rural areas and coastal communities. The “line” itself is a dedicated mobile phone number used to take orders. What sets it apart from older dealing models is its systematic exploitation of vulnerable people: children, adults with addiction, and those with few economic alternatives.

The study covered 44 of the UK’s 45 territorial police forces and included interviews and fieldwork in three separate cities. Its goal was to map the totality of drug market violence as it actually exists, rather than as policy and media typically portray it. Researchers argue that focusing only on rival gang shoot-outs and territorial disputes obscures much of what makes these networks so destructive.

Three Forms of Drug-Related Violence, Not One

Academic frameworks for understanding drug-related violence have leant heavily on American research for decades. The foundational model, developed by criminologist Paul Goldstein in 1985, divides drug-related violence into three broad types. First, violence the psychopharmacological effects of substances cause individuals to commit. Second, violence people commit to fund a drug habit. Third, “systemic” violence: the kind inherent to the illegal trade itself.

Peter Reuter later refined this by splitting systemic drug market violence into two strands: competitive violence between rival groups, and internal violence within criminal organisations. The new UK study adds a third strand that researchers rarely examine: enforcement-related violence, meaning the harm that flows from policing itself.

Together, these three forms paint a far more complete and far more troubling picture of the human cost of the illicit drugs trade in Britain.

Who Gets Exploited and How

People who end up in County Lines networks largely come from backgrounds of economic deprivation. Researchers estimate that thousands of vulnerable individuals across the UK face coercion, debt-bonding and threats each year within these networks. Initial recruitment may look voluntary. Over time, it rarely stays that way.

“If I Don’t Do This, What’s Going to Happen to Me?” Internal Drug Market Violence and Exploitation

One of the study’s most striking findings is how deeply internal drug-related violence defines the County Lines model. Researchers use “internal violence” to mean coercion, threats, and physical harm directed at people working within the network rather than rival groups.

Ollie was 14 years old when a family acquaintance first recruited him. The man asked him to deliver a bag and return with money. Ollie refused. The response was direct: “If you don’t, then you’ll end up getting hurt.”

The escalation was swift. On a later run, Ollie opened the bag and found a firearm alongside large quantities of crack cocaine and heroin, to be exchanged for £50,000 in cash. Afterwards, he learned he had to work every single day until he “forgot” what he had seen.

“It could be today that I end up dead, or the next day, or any minute,” he recalled. Threats extended to his mother and aunt. One police officer told researchers this tactic was common. Parents, siblings and other family members regularly face accountability for “drug debts”: windows smashed, cars wrecked, petrol bombs thrown at garage doors.

Cuckooing: When Home Becomes a Crime Scene

This form of internal drug-related violence also drives a practice known as cuckooing. Criminal groups take over the homes of vulnerable adults, often people with addiction, and use those properties as bases for storing and selling drugs.

Tom was in his late forties. He had used heroin for two decades and experienced cuckooing three times. He described how what started as a seemingly mutual arrangement deteriorated quickly.

“They start off the first couple of days looking after you,” he said. “Then gradually it’s just less and less, and you just can’t get rid of them because you end up owing them money.”

The violence Tom endured was severe. Dealers held a machete to his head. They broke his jaw twice. They stabbed him in the leg.

Researchers caution against framing everyone in these networks as a passive victim. The concept of “constrained choice” matters here. Involvement often reflects a rational response to severe economic deprivation and social marginalisation. Even so, the drug-related violence sustaining these networks remains a grim reality for many people inside them.

When Enforcement Itself Becomes Drug Market Violenc

Perhaps the report’s most challenging argument concerns policing as a source of harm. Researchers call this “enforcement-related violence.” Many will find the idea uncomfortable. The fieldwork evidence, though, is hard to set aside.

During ride-alongs with a dedicated County Lines disruption team, a researcher watched officers try to stop a suspect from swallowing drugs. The suspect was a non-English-speaking man from a European country. Officers shouted at him, forced him to the ground, slapped and punched him while he cried out. They eventually recovered the drugs. The man wept.

A Guidance Gap With Deadly Consequences

The incident echoes a known problem. In 2017, two young men in London died after officers blocked their airways while trying to stop them swallowing drugs. Following those deaths, the Metropolitan Police updated its guidance. Officers were told not to stop suspects from swallowing drugs once wraps were already in the mouth. The researchers’ observation suggests this guidance has not spread to all forces.

Tom described multiple encounters with police that felt, to him, no different in character from what he experienced at the hands of County Lines dealers. A woman named Liz, who used heroin and crack cocaine in the 1990s, recalled police arresting her while she walked her young daughter to school. Officers dragged her into a car while her child screamed and punched her repeatedly in the head. One told her: “No one will ever miss you.”

Researchers are explicit on one point. They do not equate lawful policing with criminal gang activity. They are not arguing all enforcement is illegitimate. Their argument is analytical. Policymakers and researchers who want to understand the full cost of drug market violence in the UK must account for the harms enforcement itself produces. Ignoring this, the authors argue, means accepting that state violence deserves less scrutiny than individual violence. That position carries serious ethical and public health consequences.

Can Policing Target Drug-Related Violence Instead of Supply?

Amid the bleaker findings, the report identifies something more encouraging. A growing number of officers have rethought what success in drugs policing means.

“The drugs are never, ever going to stop,” one retired force lead told researchers. “You’re never going to stop that. But you can actually do something about the children, and the vulnerability.”

Another inspector described a goal not of eliminating supply but of stripping out exploitation. “We want gangs, if they want to deal drugs, to do it themselves, like the old school way back in the nineties. They didn’t use kids. They didn’t use vulnerable adults. That’s the vision: take out the vulnerability.”

Scoring Harm, Not Just Arrests

One force built a scoring system to rank active County Lines operations by the harm each inflicts on the community. Officers call it a “harm score.” It determines which operations to prioritise. Rather than counting drugs seized or arrests made, the force measures whether drug-related violence and exploitation are actually falling.

This approach reflects what researchers call “harm reduction policing.” The framework shifts emphasis away from supply reduction and towards minimising the harms the drug trade produces, without necessarily eliminating the market itself.

Comparable approaches exist elsewhere. In Copenhagen, police selectively targeted dealers known to use violence against users while leaving peaceful dealers alone. In parts of the United States, the Ceasefire initiative targeted those who used violence in drug markets specifically. The message was deliberate: dealing could continue, but violence would not be tolerated.

The political obstacle remains significant. The UK national drug strategy still prioritises “breaking supply chains.” Home Office targets require forces to close at least 2,000 County Lines. That metric drives enforcement activity regardless of the violence or vulnerability levels attached to any given operation. Harm reduction goals and supply-reduction targets frequently pull in opposite directions.

Rethinking What Drug Market Violence Actually Means

The study’s central argument is conceptual. Its implications are practical. The dominant public image of drug market violence, gang rivalries, shootings, postcode wars, is incomplete rather than wrong. Focusing on visible, sensational conflict means policy and media attention consistently overlook the everyday coercion of young people and vulnerable adults, the psychological manipulation keeping them trapped, and the physical force officers sometimes use in these networks.

Feminist scholarship on domestic violence offers a useful parallel. Researchers challenged society to look beyond street crime and stranger violence and recognise harm happening inside homes. They showed that how we define violence shapes what we can do about it. The authors of this study make the same argument for drug-related violence: drawing the boundary too narrowly leaves too much harm unaddressed.

Progress Worth Noting

There are signs of change. Police and statutory services increasingly recognise young people and vulnerable adults caught up in County Lines as victims of exploitation rather than accomplices in crime. That shift carries real consequences. It affects how people interact with officers, whether they receive support or prosecution, and how communities understand the networks operating within them.

Victim identification, though, remains inconsistent. People exploited by County Lines often do not match officer expectations of what a “real” victim looks like. Many do not identify themselves as victims at all. That is frequently a legacy of years of marginalisation that predates any involvement with drug networks.

The Progression

The report calls for further research, particularly research involving people with lived experience of exploitation, to deepen understanding of hidden harms within County Lines. It also calls for the development and formal evaluation of harm reduction policing approaches that target drug-related violence specifically, rather than drug supply in general.

The study ultimately reminds us that drug markets are not uniformly or inevitably violent despite how media and policy portray them. Most transactions happen peacefully. Violence is a contingent feature of the illegal drugs trade, not an intrinsic one. That distinction matters enormously. If violence is contingent, we can reduce it.

But only if we are willing to look at all of it.
