What the 2026 YouGov Data Reveals

Public attitudes towards cannabis in the United Kingdom remain complex. Cannabis is widely recognised, medical access has existed under specialist prescription since 2018, and international approaches to regulation continue to evolve. Recreational cannabis nevertheless remains illegal under current UK law.

YouGov polling published in April 2026 provides a detailed snapshot of how British adults view cannabis use, potential harm, criminalisation, decriminalisation and legalisation.

The findings do not show an overwhelming public mandate for one particular policy. Instead, they reveal a closely divided country in which many people support reform while continuing to recognise possible health and social risks.

What Did the 2026 YouGov Survey Examine?

YouGov surveyed 2,053 British adults about their experience of cannabis and their attitudes towards future policy.

The research examined:

Whether respondents had previously used cannabis.
Whether they would consider using it in the future.
Support for or opposition to legalisation.
Preferences between criminalisation, decriminalisation and legalisation.
Perceptions of harm.
Whether prohibition prevents drug use.
Differences by age and political affiliation.

The results provide useful insight into public opinion at the time of the survey, but they should not be interpreted as a prediction of future legislation.

How Many Britons Have Used Cannabis?

YouGov found that 37% of British adults said they had used cannabis at least once.

This means experience of cannabis is not limited to a small or isolated group. More than one-third of respondents reported direct personal experience, although lifetime use differed considerably between age groups.

Reported lifetime use was highest among adults aged between 25 and 49, at approximately 47%.

Lower proportions were recorded among:

Adults aged 18 to 24, at 23%.
Adults aged 65 and over, at 25%.

These figures may reflect differences in generation, willingness to disclose use, social attitudes and opportunities for exposure.

Would People Consider Using Cannabis in the Future?

The survey found that 15% of Britons would consider consuming cannabis in the future.

Among people who had previously used cannabis, 29% said they would consider doing so again. Among those who had never used cannabis, 7% said they might consider trying it.

This distinction matters because lifetime experience does not necessarily indicate current or regular use.

Is the British Public in Favour of Cannabis Legalisation?

When asked a two-way question about legalisation, the public was closely divided:

47% supported legalising cannabis.
43% opposed legalising cannabis.
The remaining respondents answered that they did not know.

This result shows slightly more support than opposition, but the difference is not large enough to describe public opinion as settled.

Wording also matters. Responses changed when participants were offered three distinct policy options instead of a simple choice between legalisation and continued prohibition.

Criminalisation, Decriminalisation or Legalisation?

When offered three possible approaches, respondents divided as follows:

35% supported keeping sale and possession as criminal offences.
33% supported legalisation.
23% supported decriminalisation.
The remainder did not know.

Taken together, legalisation and decriminalisation attracted support from a majority of respondents. However, these policies are not the same and should not be combined as though they represent a single proposal.

What Is the Difference Between Decriminalisation and Legalisation?

Criminalisation

Under criminalisation, prohibited possession, production and supply remain criminal offences. This broadly reflects the current UK approach to recreational cannabis.

Decriminalisation

Decriminalisation generally removes or reduces criminal penalties for possession of small amounts for personal use.

Cannabis may remain unlawful, while possession is dealt with through a warning, civil penalty, health intervention or another non-criminal response.

Decriminalisation does not necessarily create a lawful retail market.

Legalisation

Legalisation permits specified cannabis-related activities under a new legal framework.

Depending on the model, this may include:

Licensed cultivation.
Age-restricted possession.
Regulated production.
Product testing.
Licensed retail supply.
Advertising restrictions.
Taxation.

Legalisation does not usually mean that cannabis becomes completely unrestricted.

Do Britons Believe Cannabis Is Harmful?

Support for reform does not mean that respondents considered cannabis harmless.

YouGov reported that 57% of Britons viewed cannabis as harmful to regular users. This included 22% who considered it very harmful.

Only 7% said cannabis was not harmful at all.

This suggests that many people distinguish between recognising potential risks and supporting criminal penalties.

Public Concern About Health Risks

Cannabis can affect individuals differently, and risk varies according to factors including:

Age.
Frequency of use.
THC concentration.
Personal and family medical history.
Method of consumption.
Use alongside alcohol or other substances.

Researchers continue to investigate associations between frequent high-THC cannabis use and outcomes including dependence, anxiety and psychotic disorders in susceptible individuals.

Public discussion about reform therefore involves more than choosing between prohibition and unrestricted access. Any regulatory model would need to consider product potency, health information, age controls and access to support.

Does the Public Believe Prohibition Prevents Cannabis Use?

YouGov found that 60% of Britons believed making a drug illegal is ineffective at preventing people from using it.

Even among respondents who supported retaining criminalisation, a substantial proportion doubted that illegality effectively prevents consumption.

This highlights an important distinction between two questions:

Is cannabis potentially harmful?
Is criminal prohibition the most effective way to manage those harms?

A person may answer yes to the first question while remaining sceptical about the second.

Should Drug Use Be Treated as a Health or Criminal Issue?

The largest group of respondents, at approximately 40%, believed drug use should be treated equally as a health and criminal justice issue.

Other respondents divided between prioritising a health-based approach and viewing drug use mainly as a criminal matter.

This balance helps explain why public opinion cannot be reduced to a simple pro-cannabis or anti-cannabis division.

Many people appear to favour a mixed approach involving:

Education.
Treatment.
Harm reduction.
Controls on supply.
Enforcement against organised crime.

How Does Age Affect Opinion?

Support for legalisation generally declined with age.

On the three-option question, legalisation was selected by approximately 38% to 42% of respondents in age groups below 50. This fell to around 20% among adults aged 65 and over.

Older respondents were more likely to favour keeping cannabis as a criminal offence, with approximately 47% of those aged 65 and over selecting that option.

Possible explanations include generational differences in:

Personal experience.
Media coverage.
Social attitudes.
Perceptions of risk.
Views on policing and personal liberty.

How Does Political Support Affect Opinion?

Attitudes also varied between supporters of different political parties.

Green Party voters were the most supportive of legalisation, with 54% selecting that option on the three-way question.

Conservative supporters were the most likely to favour keeping cannabis criminalised. Reform UK supporters also leaned more towards criminalisation, although opinion within each political group remained mixed.

Labour and Liberal Democrat voters were distributed more evenly between the available policy options.

These figures describe the opinions of party supporters surveyed. They should not be treated as a substitute for each party’s current published policy.

Do People Understand Political Party Cannabis Policies?

YouGov found considerable uncertainty about which political parties support cannabis-law reform.

More than half of respondents said they did not know which major parties supported legalisation.

Only 31% identified the Green Party as supporting legalisation, while 7% believed the Liberal Democrats supported it.

This suggests that public understanding of party positions is limited, even as cannabis policy becomes more prominent in political debate.

What Does Current UK Law Say?

Cannabis remains a Class B controlled drug in the United Kingdom.

Without a relevant licence or legal exemption, offences can include:

Possession.
Possession with intent to supply.
Production or cultivation.
Supply or offering to supply.
Importation and exportation.

The maximum penalty for possession of a Class B drug can include five years’ imprisonment, an unlimited fine or both.

The maximum penalty for supply or production can include 14 years’ imprisonment, an unlimited fine or both.

Actual outcomes depend on the circumstances, evidence, quantity, previous offences and decisions made by police, prosecutors and courts.

Medical Cannabis in the UK

Certain cannabis-based medicinal products have been available under specialist prescription since November 2018.

This change did not legalise recreational cannabis or create a general retail market.

Medical access normally involves:

Clinical assessment.
A prescribing decision by an appropriately qualified specialist.
Dispensing through an authorised pharmacy.
Ongoing clinical supervision where required.

NHS prescribing remains limited. Some patients access medical cannabis through private clinics after clinical assessment.

Consumer CBD Products Are Different

Consumer CBD products should not be confused with prescribed cannabis-based medicinal products.

CBD itself is not generally treated in the same way as controlled THC, but finished products must comply with all applicable UK requirements.

Depending on the product category, relevant considerations may include:

Controlled cannabinoid content.
Novel Foods requirements.
Product safety.
Labelling.
Advertising and medical claims.
Laboratory testing.

A product is not automatically lawful simply because its label says CBD or hemp.

How Does the UK Compare With Other Countries?

Cannabis policy is developing differently around the world. There is no single international model.

Canada

Canada introduced a regulated adult-use cannabis market in October 2018.

Federal law permits adults to possess limited quantities and obtain cannabis through authorised systems, while provinces and territories control many retail and age-related rules.

Germany

Germany introduced reforms in 2024 permitting adults to possess limited amounts, cultivate a restricted number of plants and participate in regulated non-profit cultivation associations under specified conditions.

The reforms did not create an unrestricted national commercial retail market comparable with Canada.

Luxembourg

Luxembourg permits limited home cultivation and private use by adults. Public possession and commercial supply remain restricted.

Malta

Malta permits limited personal possession, home cultivation and access through regulated non-profit cannabis associations.

Is the UK an International Outlier?

The UK maintains a stricter approach to recreational cannabis than countries that have introduced home cultivation, non-profit associations or regulated retail markets.

However, European policy remains diverse. Many countries continue to prohibit commercial recreational supply even where penalties for personal possession have been reduced.

It is therefore more accurate to describe the UK as one of several countries retaining prohibition rather than suggesting that Europe has adopted one uniform alternative.

What Could a Regulated UK Market Involve?

If a future government decided to legalise cannabis, Parliament would need to establish a detailed regulatory framework.

Issues requiring consideration could include:

Minimum age limits.
Licensed cultivation.
THC concentration controls.
Independent product testing.
Plain packaging.
Advertising restrictions.
Taxation.
Road safety.
Workplace policies.
Public-use restrictions.
Mental-health safeguards.
Treatment and harm-reduction funding.

The YouGov data does not tell policymakers which model to adopt. It shows only how respondents viewed broad policy choices at the time of the survey.

What Arguments Are Made in Favour of Reform?

Supporters of reform commonly argue that a regulated approach could provide:

Product testing and batch traceability.
Controls on age and retail access.
More accurate cannabinoid labelling.
Reduced criminal penalties for personal possession.
Tax revenue.
Reduced income for illegal suppliers.
More direct public-health communication.

Whether these outcomes occur depends on the design, implementation and enforcement of the regulatory model.

What Concerns Are Raised About Reform?

Critics and cautious supporters commonly raise concerns about:

Increased availability.
Youth access.
High-potency products.
Dependence.
Mental-health outcomes.
Impaired driving.
Commercial advertising.
Normalisation of frequent use.

International experience suggests that legalisation does not remove the need for enforcement, education, treatment or product controls.

What Does the YouGov Poll Mean for Future UK Policy?

The findings indicate that public opinion is more receptive to reform than a simple description of current law might suggest.

However, support remains divided and sensitive to how the question is asked.

The survey suggests several conclusions:

A narrow plurality supports legalisation on a two-way question.
No single option commands a majority when three policy choices are offered.
A majority favours either decriminalisation or legalisation.
Most respondents still recognise potential harm.
Most doubt that prohibition prevents use.
Attitudes differ substantially by age and political affiliation.

These findings may encourage further political discussion, but they do not change UK law.

Why Accurate Public Information Matters

Cannabis policy is often discussed through slogans, personal experiences and political assumptions.

Reliable polling helps identify public attitudes, but it should be considered alongside:

Medical and public-health evidence.
Crime and policing data.
International regulatory outcomes.
Patient experiences.
Economic evidence.
Views from affected communities.

No single survey can answer every question surrounding legal reform.

No. Germany permits limited possession, home cultivation and non-profit associations under specified conditions, but it has not introduced a nationwide unrestricted commercial retail market.

Does the YouGov poll mean cannabis will be legalised?

No. Opinion polling can influence debate, but any legal change would require government policy, parliamentary approval and a detailed regulatory framework.

Final Thoughts

The 2026 YouGov data presents a British public that is closely divided but increasingly open to reconsidering current cannabis policy.

Support for legalisation narrowly exceeds opposition when respondents are offered a simple two-way choice. When criminalisation, decriminalisation and legalisation are separated, no single policy attracts majority support.

The findings also show that reform and risk are not viewed as opposites. Many Britons recognise that cannabis may be harmful while doubting that criminal prohibition effectively prevents its use.

Future policy discussions will need to consider this complexity alongside scientific evidence, medical access, public safety, policing and experience from other countries.
