Legalising Drugs: The Better Option or Admittance of Failure?

Yet, despite their efforts, illicit drug markets continue to thrive, addiction remains stubbornly persistent, and criminals grow fat on what is prohibition’s unfortunate byproduct—black markets.

While accurately assessing the total value of the global illicit drug market is inherently challenging, conservative estimates place it in the hundreds of billions of dollars per year. As frustration mounts, some policymakers have started to ask: what if, instead of throwing money at a failing war, we simply legalise the very thing we’ve been trying to eradicate? 

But does legalisation really work? Does it reduce crime and addiction, or merely make dangerous substances more socially acceptable? Can governments regulate drugs better than criminal enterprises, or will they simply end up replacing cartels with tax collectors? If the future points towards legalisation, what lessons should policymakers take from the past?

We Need to talk about Prohibition

The case against prohibition is remarkably simple: it only works up to a point. Bans on substances of all kinds (including narcotics) have succeeded in criminalising vast swathes of the population but have done little to curb demand. 

The lessons of history are instructive in that regard. America’s great experiment with alcohol prohibition in the 1920s did not turn the country into a beacon of sobriety. Instead, it fuelled a thriving black market run by organised crime, and produced a spectacular rise in gangster-related violence, making figures like Al Capone a household name. 

The modern war on drugs has yielded similar results—just with better-funded, heavily militarized, transnational cartels which Capone could only dream of.

By 1933, policymakers had thrown in the towel and decided to legalise alcohol once more, realising that it was better to tax and regulate the enterprise than hand it over to bootleggers and owners of the many speakeasies which had popped up during the U.S.’ Prohibition Era  (1920-1933).

Fast forward to the present day, and the war on drugs has followed a similar trajectory—except this time, the scale is global. The United States, which paved the way in modern drug prohibition, has spent trillions cracking down on narcotics since the 1970s; but, has little to show for it. 

Cocaine, heroin, and methamphetamine remain widely available, and the opioid crisis has led to a record in overdose deaths. Meanwhile, Latin America has suffered decades of cartel violence, all while demand for drugs in the West remains as insatiable as ever.

If prohibition’s goal was to eliminate drug use, it has been a spectacular failure. If the goal was to keep criminals living in the lap of luxury, then it has been a roaring success.

Cannabis: Legalisation’s Test Case 

For those advocating a path towards leniency, cannabis legalisation has been the first serious test. Since Colorado and Washington became the first U.S. states to legalise recreational marijuana in 2012, Canada, Uruguay, and parts of Europe have followed suit. The results have been, if not quite revolutionary, at least instructive.

The good news? The great moral panic over legalisation has not materialised. Cannabis use has not skyrocketed, crime has not spiralled out of control, and society has not been zombified by THC-induced apathy. In Canada, where cannabis has been legal since 2018, usage rates have remained fairly stable, and the government has enjoyed a steady stream of tax revenue. Colorado alone has raked in over $2 billion in cannabis taxes since legalisation, money that—unlike cartel profits—goes to the funding of schools and other public services.

The bad news? The black market is proving annoyingly resilient. In California, where cannabis is legal, illegal growers still dominate the supply chain, largely because regulation has made legal weed more expensive. It turns out that when faced with a choice between government-sanctioned cannabis and a cheaper, tax-free alternative, many consumers opt for the latter.

Another issue is potency. Today’s legal cannabis is far stronger than the marijuana of previous generations, and some studies suggest a link between high-potency strains and psychiatric disorders such as schizophrenia. Conservative columnist Peter Hitchens, who has turned the issue of cannabis legalisation into a hobby horse of sorts, proposed a causal link between use of marijuana by Southport killer Axel Rudakubana and his brutal killing of three young girls. 

While the jury is still out on that, it highlights the importance of regulatory oversight—not just on whether certain drugs are legal, but on how they are produced and consumed.

Hard drugs, Harder Choice 

Policymakers are nervous, however, at the thought of outright legalisation of harder substances, like heroin and cocaine, fearing that would spell disaster for public health.

Yet with the fentanyl epidemic already ravaging the U.S., driving a record of annual overdose deaths, realists argue that, at least in the short to medium term, a safe supply of opioids is the only way to prevent fatalities. 

The logic is simple: if people are going to use these drugs anyway, since they are heavily addicted, better these come from a controlled source than a street dealer selling unpredictable, often lethal substances.

The Deeper Problem

However,  legalisation alone is not a magic fix—if at all successful, it must be accompanied by well-funded addiction services, harm-reduction strategies, and education campaigns. 

Switzerland offers one model. Since the 1990s, the country has run heroin-assisted treatment programmes, where addicts receive controlled doses under medical supervision. The results have been encouraging: overdoses have plummeted, crime related to heroin use has declined, and participants have shown improvements in employment and health. Similar programmes exist in the Netherlands and Germany, with comparable outcomes.

Yet the elephant in the room, which few dare point out, is the why; why are our fellow citizens turning to drugs, soft or hard, in the first place? However more difficult it may prove to be (and it very much is) , policy makers need to address the spiritual malaise, loneliness,feelings of alienation wrought by modernity, as well as socioeconomic woes which  are driving the demand for escapist drugs in the first place. 

Should they fail to do so, decriminalisation and legalisation risk becoming little more than admissions of failure.

Where to go From here

With the current approach having failed so spectacularly, the drug debate is shifting. The question now is no longer whether prohibition works—it does not—but what should replace it.

A tiered approach seems the most pragmatic. Cannabis legalisation has demonstrated that regulated markets can function, provided proper controls are in place. Decriminalisation is a humane alternative to punitive drug laws, reducing harm without encouraging widespread use. For harder drugs, strict regulation rather than outright legalisation may be the better path, with supervised treatment programmes for those struggling with addiction.

Ultimately, drug policy should be driven not by ideology, but by evidence. A century of prohibition has left a legacy of violence, addiction, and wasted resources. The challenge now is to build a system that minimises harm, maximises public health, and acknowledges the simple truth that, whether legal or not, people will continue to seek out mind-altering substances. Apart from tackling the root causes of the demand for them, the question now is whether governments want to acknowledge that reality—or continue pretending they can outlaw it out of existence.
