When will the UK legalise cannabis?

Short answer: not before 2030, and that is optimistic. The honest answer is that the UK has finally started the process — an official evidence review, an expert panel, the first government that has not blocked the conversation outright — but has not committed to anything that would actually change the law. Here is where things actually stand, what is holding it back, and how it will most likely happen.

Senior Police officers are still out of touch

Senior police officers at a Conservative party conference advocated for the UK government to reclassify cannabis from a class B to a class A drug, which would elevate it to the same legal level as heroin or cocaine, significantly increasing the penalties for those caught using or selling cannabis.

This rather extreme proposal contrasts with the global trend of easing restrictions on cannabis.

Were they drunk?

According to the National Conference of State Legislatures, as of September 2021, 18 states, two territories, and the District of Columbia have enacted laws legalizing recreational marijuana use for adults.

In Europe, countries like Portugal, the Netherlands, and Spain have long ago taken steps toward cannabis legalization or decriminalization.

South Africa’s supreme court declared the dagga ban unconstitutional in 2018, and Canada and Uruguay were the first nations in decades to acknowledge cannabis as a legitimate commodity, legalizing it in 2013 and 2018, respectively.

Germany finally did it: possession and home growing became legal in April 2024, and the licensed-sales pilot clubs are operating — an experiment the UK watches from across the Channel with its arms folded.

Thailand’s cannabis policy is way more progressive than the UK

Even Thailand’s notoriously strict government lifted its ban in 2022, releasing thousands of non-violent drug offenders and distributing a million seedlings to bolster the country’s emerging marijuana industry.

As the world shifts its stance on cannabis, it’s important to understand the historical context of the UK’s position.

In the 1960s, marijuana became a contentious issue in the culture wars, culminating in the 1967 arrest of Mick Jagger and Keith Richards.

While the UK’s “war on drugs” wasn’t as racially charged as in the US, the stereotype of young black men as pushers or cananbis addicts contributed to racial tensions that erupted into riots in the 1980s.

In the late 2000s, the debate over “skunk” and the influence of tabloids fueled the notion that modern cannabis was more potent and potentially dangerous.

However, there is no evidence of widespread effects on society. Schizophrenia rates in the UK have remained stable over time despite the number of cannabis users increasing.

Furthermore, psychosis rates clearly have not increased in areas where cannabis has been legalized – we would be seeing an effect in the US and Canada if this propaganda was actually based on fact. It is not.

Politicians often hesitate to support cannabis legalization, fearing the perception of being “soft on crime.” The truth is, by supporting prohibition, they are actually encouraging and preserving crime.

Keeping the cannabis industry underground can actually contribute to criminal activity, such as violence around grow-houses as well as the exploitation of workers.

The public are also at risk as prohibition ultimately means unregulated cannabis that may contain dangerous pollutants. And no option for the young to use less powerful cannabis.

Addressing racial disparities in policing is fundamental, as the “smell of cannabis” has been used to justify stops and searches, perpetuating resentment and tension for years.

The UK stands out among conservative countries for its continued resistance to cannabis legalization.

In contrast, right-wing politicians in Israel and the US have embraced the idea, with US lawmakers now discussing social equity plans to redress the harms caused by the drug war, such as the Marijuana Opportunity Reinvestment and Expungement (MORE) Act.

Despite the UK’s conservative stance, (and a little progress in the medical cannabis sector) public opinion is changing.

Polling from YouGov, UnHerd and others now consistently finds more than half of Britons support legalisation — and support keeps climbing with every cohort under 50.

And let’s not forget, the UK is a leading exporter of medicinal cannabis, although it is not widely available to citizens due to dated and unscientific laws. What a farce.

The UK simply cannot afford to ignore worldwide policy changes

Although it would appear that Keir Starmer wants to keep his head in the sand despite the financial and social benefits on the table.

The US is not a 100% successful framework for legal cannabis policy, though with recent changes to federal legalization the tide is quickly turning in favour of supporting cannabis businesses, instead of fighting therm.

The Netherlands has also faced challenges, as coffee shops selling marijuana operate in a legal gray area and supply chains have been linked to criminal activity. This is now changing as the Netherlands tests out a regulated growing supply chain.

Meanwhile, Canada has faced criticism for allowing corporate monopolies to dominate the market, which has led to concerns about quality and affordability.

As the tide of global opinion continues to turn in favor of cannabis legalisation, it becomes increasingly difficult for the United Kingdom to justify its resistance to change.

Where the UK actually stands in 2026

The question	The 2026 answer
Is cannabis legal in the UK?	No. Recreational use remains Class B — up to 5 years possession, 14 years supply.
Is medical cannabis legal?	Yes, since 2018 — but only via private clinics, effectively out of NHS reach for most patients.
What has the government actually done?	Ordered an evidence review and appointed an expert panel. No bill, no timetable, no vote.
Could a change come this parliament?	Not through government. Any movement is most likely to start as backbench or Lords pressure.
What about devolved nations?	Drugs policy is reserved to Westminster — though Scotland and Wales both back reform louder than London.

The shape of the thing is now clear: Germany legalised in 2024, the US rescheduled at federal level and keeps adding states, Thailand experimented loudly, and even France is trialling medical cannabis while its President muses aloud. Britain exports medical cannabis by the tonne while arresting its own citizens for the same plant — the farce described below has not aged a day.

The three realistic paths to legalisation

The medical expansion. Most likely first step: widen NHS access so medical cannabis stops being a private-clinic luxury. Once GPs can prescribe it, the recreational question gets easier to ask.
The pilot scheme. The German club model or a Dutch-style regulated supply trial in one city. This is what the evidence review exists to feed — expect the government to authorise a “study” long before it authorises a market.
The economic argument. A fiscal crisis concentrates minds wonderfully. Treasury estimates of a legal UK market run into the billions in tax; the current government will not act on this, but a future Chancellor might not have the luxury of squeamishness.

The realistic timeline: medical expansion first (possible this parliament), then regulated pilots (early 2030s), full legalisation last — and only when a government decides it can win the Daily Mail front page rather than lose it.
