Cannabis Laws in the United Kingdom
Cannabis remains Class B in UK law with significant penalties, though enforcement has become inconsistent.
This article is general information, not legal advice. Laws change; check current rules with official sources or a lawyer.
Cannabis is illegal in the UK but enforcement has softened considerably. Most possession arrests now result in warnings or fines rather than prosecution. Medical prescribing exists on paper but barely happens through the NHS—most patients turn to private clinics. CBD is legal if it meets strict controls, but the novel food regulations have dried up the market. The law hasn't changed, but policing has.
Legal framework
Cannabis is controlled under the Misuse of Drugs Act 1971, which classifies substances into Classes A, B and C [1]. The drug was reclassified from Class B to Class C in 2004, then moved back to Class B in January 2009 [1][2]. It covers herbal cannabis, resin (hashish), and cannabis oil, excluding compliant CBD products.
The Misuse of Drugs Regulations 2001 govern lawful uses [3]. Cannabis-based products for medicinal use (CBPMs) were moved from Schedule 1 to Schedule 2 on 1 November 2018, enabling prescription by specialist doctors on the General Medical Council's Specialist Register [3].
The law applies uniformly across England, Wales, Scotland and Northern Ireland, though Scotland has its own prosecution system (the Crown Office and Procurator Fiscal Service) which exercises independent discretion.
Penalties for possession, supply and production
Statutory maximums under the Misuse of Drugs Act 1971 for Class B offences are [1]:
- Possession: up to 5 years imprisonment, an unlimited fine, or both
- Supply or production: up to 14 years imprisonment, an unlimited fine, or both
- Import/export: up to 14 years under the Customs and Excise Management Act 1979
In practice, most first-time possession offences involving small quantities are dealt with by a cannabis warning (a non-statutory police disposal) or a Penalty Notice for Disorder (£90 fine) rather than arrest. This approach is force-dependent and has been controversial: several police forces have de-prioritised possession enforcement, while others prosecute more actively.
A conviction counts as a criminal record and can affect employment, travel (notably to the United States), and immigration status. Driving with THC in your system is a separate offence under section 5A of the Road Traffic Act 1988, with a 2 µg/L blood THC limit —low enough that recent use will typically exceed it.
Medical cannabis
Since 1 November 2018, specialist doctors registered with the General Medical Council can prescribe unlicensed cannabis-based products for medicinal use [3].
Three licensed cannabis-derived medicines are also available on the NHS:
- Epidyolex (cannabidiol) — for certain rare seizure disorders
- Sativex (nabiximols) — for multiple sclerosis-related spasticity
- Nabilone — a synthetic cannabinoid for chemotherapy-induced nausea and vomiting
Despite the legal change, NHS prescribing of unlicensed CBPMs remains very limited. NICE guideline NG144 (2019, updated) recommends against routine use for chronic pain and takes a cautious stance on other conditions due to limited high-quality evidence [4]. An estimated tens of thousands of patients access cannabis through private clinics, paying for consultations and monthly prescriptions entirely out of pocket, as NHS specialists rarely prescribe.
High-profile cases involving children with severe epilepsy (Alfie Dingley, Billy Caldwell) drove the 2018 rule change, but very few NHS prescriptions have followed even in similar cases.
CBD and hemp
CBD products sold to consumers are legal in the UK subject to strict conditions. The Food Standards Agency classifies ingestible CBD as a novel food, meaning products require FSA authorisation to be sold legally; the FSA maintains a public list of products linked to validated applications [5].
Critically, finished consumer CBD products must not contain more than 1 mg of controlled cannabinoids (including THC and CBN) per container, per Home Office guidance —this is an absolute limit, not a percentage, and is stricter than the EU's approach. Products exceeding this are legally controlled drugs regardless of CBD content. Products making medicinal claims also fall under MHRA (Medicines and Healthcare products Regulatory Agency) regulation.
Hemp cultivation requires a Home Office licence. UK-grown hemp flower and leaf cannot legally be processed into CBD in the UK even from low-THC varieties—extract must come from imported material or from stalks and seeds only.
Enforcement in practice
Enforcement has diverged significantly from the statutory law. Cannabis warnings and out-of-court disposals now handle most possession cases. Some police and crime commissioners have piloted diversion schemes offering education or treatment instead of prosecution for personal-use possession (e.g., Thames Valley, West Midlands, Durham).
In late 2022, then-Home Secretary Suella Braverman suggested reclassifying cannabis to Class A, but no such change occurred and cannabis remains Class B [6].
Cannabis 'social clubs' operating openly (a model tolerated in Spain) do not have legal recognition in the UK; participants can be prosecuted for possession, supply, or production regardless of any club membership.
Recent developments
- November 2018: CBPMs moved to Schedule 2, enabling specialist prescribing
- 2019: NICE guideline NG144 published with cautious recommendations on medical cannabis [4]
- 2021–2023: FSA novel food process significantly narrowed the legal CBD market; thousands of products removed from sale [5]
- March 2024: London Drugs Commission (chaired by Lord Falconer) recommended partial decriminalisation of possession of natural cannabis but stopped short of legalisation
As of November 2026, no legislation to decriminalise or legalise recreational cannabis has been introduced by the UK government.
