Understanding cannabis law in the UK is important for anyone searching for information about cannabis, medical cannabis, CBD and cannabis-related products.
The UK’s cannabis laws can be confusing because cannabis remains a controlled drug, while certain cannabis-based medicines can legally be prescribed by specialist doctors. CBD products also have their own regulatory requirements.
In this guide, London Cannabis Social Club explores the current UK cannabis laws and explains the key differences between recreational cannabis, medical cannabis and CBD.
Is Cannabis Legal in the UK?
In general, recreational cannabis is illegal in the UK.
Cannabis is classified as a Class B controlled drug under the Misuse of Drugs Act 1971. UK law generally prohibits unauthorised possession, supply, production, importation and exportation of cannabis.
The maximum penalties listed by the UK Government include:
- Up to 5 years in prison, an unlimited fine, or both for possession of a Class B drug.
- Up to 14 years in prison, an unlimited fine, or both for supplying or producing a Class B drug.
Actual penalties depend on the circumstances of the offence.
Therefore, searches such as “weed legal UK”, “is cannabis legal in London?” and “can I buy weed legally in the UK?” need to be understood within this legal framework.
Medical Cannabis and UK Law
One of the most important changes to UK cannabis law occurred in 2018, when certain cannabis-based products for medicinal use were moved into Schedule 2 of the Misuse of Drugs Regulations.
This allowed appropriately qualified specialist doctors to prescribe certain cannabis-based medicinal products where clinically appropriate.
Medical cannabis is therefore legal in the UK in specific circumstances and through the appropriate medical pathway.
It does not mean that recreational cannabis became legal.
Who Can Prescribe Medical Cannabis?
Medical cannabis prescriptions are subject to specific requirements.
NHS England explains that cannabis-based products for medicinal use can be supplied under the prescription or direction of a clinician on the General Medical Council’s Specialist Register.
Specialist doctors must consider the patient’s circumstances, available evidence, potential risks and whether the medicine is appropriate.
Private specialist doctors can also legally prescribe qualifying cannabis-based medicinal products within the applicable UK framework.
Can a GP Prescribe Cannabis?
Medical cannabis should not be confused with ordinary prescriptions from a GP.
NHS guidance states that cannabis-based medicines are generally prescribed through specialist medical care. A hospital specialist may consider medical cannabis in certain circumstances after other treatment options have been considered.
Anyone considering medical cannabis should discuss their circumstances with an appropriately qualified healthcare professional.
Cannabis Possession in the UK
Possessing cannabis without lawful authority remains an offence.
The fact that cannabis may be prescribed medically does not mean that anyone can legally possess cannabis for personal use.
Patients who have been prescribed cannabis-based medicines should keep the medicine in its original packaging and retain relevant prescription documentation. NHS guidance recommends keeping evidence of the prescription available where appropriate.
Is Cannabis Legal in London?
Cannabis law in London follows the wider UK legal framework.
There is no separate recreational cannabis market in London. Recreational cannabis remains prohibited under UK law.
London does, however, have healthcare providers and businesses operating within legal areas of the cannabis and CBD sectors.
People searching for:
- Cannabis London
- Weed London
- Medical cannabis London
- CBD London
- Cannabis clinic London
- Cannabis dispensary London
- Cannabis near me London
should determine whether they are looking for medical services, lawful CBD products or general information.
What About Cannabis Dispensaries in the UK?
The UK does not currently have a legal recreational cannabis dispensary system comparable with some jurisdictions overseas.
This is an important distinction for people searching for “weed dispensary UK” or “cannabis dispensary London.”
A website using the term “dispensary” does not automatically mean that it is authorised to sell recreational cannabis.
Cannabis businesses dealing with controlled cannabis products may require appropriate Home Office licensing, depending on their activities.
CBD and UK Cannabis Law
CBD, or cannabidiol, has a different legal position from THC.
Pure CBD is not itself a controlled drug under the Misuse of Drugs Act. However, CBD products can contain other cannabinoids that are controlled, and products must meet the applicable legal requirements.
This means consumers should not assume that every product labelled “CBD” is automatically legal.
can also be subject to separate rules covering areas such as food and medicines.
CBD Food Products
Businesses selling CBD food products need to comply with applicable food regulations and requirements.
Consumers should therefore check product information carefully and be cautious about products making unsupported health or medical claims.
Is Growing Cannabis Legal in the UK?
Generally, cultivating cannabis without the appropriate Home Office licence is illegal, regardless of whether the plant is intended for personal use.
The Home Office states that cultivation of cannabis requires a controlled-drug licence, with separate rules applying to licensed industrial hemp cultivation.
Industrial hemp should therefore not be confused with unrestricted cultivation of cannabis for recreational purposes.
Can You Import Cannabis Into the UK?
Importing controlled cannabis without the appropriate legal authority is prohibited.
The Home Office states that cannabis is unlawful to import or export except under the applicable licensing framework.
This is particularly important for people travelling internationally with cannabis or cannabis-based products.
Medical cannabis patients should obtain appropriate advice before travelling with prescribed medicines because additional requirements can apply when controlled drugs cross borders.
Cannabis and Driving in the UK
Driving after consuming cannabis can create serious legal and safety consequences.
UK drug-driving legislation includes specific limits for certain controlled drugs, including THC. Being prescribed a medicine does not automatically mean that a person can drive regardless of its effects.
Patients using prescribed cannabis-based medicines should follow their doctor’s advice and the applicable driving rules.
If a medicine makes you unfit to drive, you should not drive.
Cannabis Law and Changing Public Attitudes
Cannabis policy continues to generate discussion throughout the UK.
London has also been the subject of significant debate around cannabis policy. The London Drugs Commission has examined issues including cannabis regulation, public health and policing.
However, policy discussions and recommendations should not be confused with a change in the law.
Recreational cannabis remains illegal in the UK.
