Harsher drug prohibition won't stop violence, argue Paul Whitehouse, former Chief Constable of Sussex Police, and Jason Reed at Law Enforcement Action Partnership (LEAP UK) which supports drug policy reform, in The BMJ today.
They say spending £40m on policies based on prohibition "is unlikely to solve the problem" and they call for drug policy to shift focus from criminal justice to public health.
Last week, the Royal College of Physicians of London joined calls for an end to criminal sanctions against people who take drugs such as heroin, cocaine, and cannabis for non-medical reasons, saying the criminal justice system "is not the place to address the often complex needs of people addicted to drugs."
Earlier this month, after a spate of violent crime, the UK Home Office released its Serious Violence Strategy, stating that the government's response "must tackle the misuse of drugs" as a priority, with more expected from the police.
But the authors point out that only four years ago, the same department released a report acknowledging that drug laws have no real impact on drug use.
They highlight the failed, dangerous and expensive pursuit of a punitive drug policy.
For example, the Home Office has prioritised tackling "county lines," where gangs recruit children to distribute drugs to provincial towns.
Yet Neil Woods, an undercover police officer and LEAP UK chairperson estimates that for the 1000 years of cumulative prison time, with each operation taking around six months to complete, the flow of drugs in any city was interrupted for only around two hours, and it's often the most vulnerable who were affected and not those at the head of the supply chain.
Woods and many colleagues now call for the control and regulation of drugs to take this $320bn global industry out of the hands of organised crime.
Reed and Whitehouse also point to the Misuse of Drugs Act 1971, that makes all drug possession and supply a crime, "but the deterrent doesn't work and drugs are more readily available than ever," they write.
Scotland now has the highest rate of drug related deaths in the EU, with 867 people dying in 2016 - more than twice as many as a decade ago, while the government's Advisory Council on the Misuse of Drugs reports that 2,677 people died from opioid overdose in 2015 in the UK. "Without the threat of criminal repercussions more people with drug problems could get help," they write.
Furthermore, each UK taxpayer spends an estimated £400 a year on drug policy, with the annual cost of class A drug use in England and Wales estimated at over £15bn and in Scotland around £3.5bn, they add.
Some police forces are taking different approaches to drug enforcement within the law, they explain. For instance, in Durham, a policy of not arresting people for drug possession and low level dealing has gained public support, while in North Wales, police are putting more focus on supportive services.
International examples also show that more humane drug policies do not lead to an increase in consumption, as proponents of prohibition argue, but to a reduction in crime and overdose deaths.
Reed and Whitehouse argue that the government's "new" strategy is already outdated. To reduce the violence from illegal trade "we should replace our enforcement led approach with regulation, taxation, support, and education in a health based strategy."
Until Westminster sees how much the public support drug policy reform "we are unlikely to see any differences in rates of street crime. When so many law enforcement voices are calling for drug law reform, we have to ask why legislators are not listening," they conclude.
