Access, Laws and Legal Alternatives

Medical cannabis has been available on prescription in the UK since November 2018. However, it remains tightly controlled, access through the NHS is limited and most patients who receive cannabis-based medicinal products do so through private specialist clinics.

This guide explains the position in 2026, including how medical cannabis may be prescribed, the difference between NHS and private access, the rules patients must follow and how prescribed cannabis differs from non-medicinal cannabinoid products.

Medical cannabis should not be confused with consumer CBD, CBG or other hemp-derived products. Prescribed cannabis-based medicines are supplied under medical supervision, whereas retail cannabinoid products must not be presented as treatments or replacements for prescribed medication.

Is Medical Cannabis Legal in the UK?

Yes, but only when it has been lawfully prescribed and supplied through an authorised medical route.

Cannabis otherwise remains a Class B controlled drug under the Misuse of Drugs Act 1971. Possessing, supplying, producing or cultivating controlled cannabis without the necessary prescription, authority or licence remains unlawful.

Changes introduced in November 2018 allowed certain cannabis-based products for medicinal use to be prescribed in the UK. These products are commonly referred to as cannabis-based products for medicinal use, or CBPMs.

The changes did not legalise recreational cannabis, home cultivation or the purchase of uncontrolled cannabis products for self-medication.

What Is a Cannabis-Based Product for Medicinal Use?

A cannabis-based product for medicinal use is a medicinal preparation containing cannabis, cannabis resin or one or more cannabinoids derived from cannabis.

Some cannabis-based medicines have received formal marketing authorisation for specific uses. Other products supplied through specialist clinics may be unlicensed medicines prescribed for an individual patient where a clinician considers this appropriate.

An unlicensed medicine is not necessarily unlawful or unsafe. However, it has not received marketing authorisation for general use in the same way as a licensed medicine. The prescribing specialist must therefore consider the available evidence, the patient’s circumstances and whether established treatments have already been tried.

Who Can Prescribe Medical Cannabis?

Initial prescriptions for unlicensed cannabis-based medicinal products must be made by a doctor listed on the General Medical Council’s Specialist Register.

On the NHS, medical cannabis can generally only be prescribed by a specialist hospital doctor or under the supervision of a specialist. A GP cannot normally initiate treatment independently, although a GP may become involved in ongoing care where an appropriate shared-care arrangement has been agreed.

Private medical cannabis clinics also use specialist doctors. Patients should check that a clinic is appropriately registered and that the doctor responsible for their treatment appears on the relevant professional register.

Which Conditions May Be Considered?

The NHS states that cannabis-based medicines are only likely to be prescribed to a relatively small number of patients.

Current NHS and NICE guidance includes limited circumstances involving:

Certain severe and treatment-resistant forms of epilepsy
Moderate to severe muscle spasticity associated with multiple sclerosis
Nausea and vomiting caused by chemotherapy when established treatments have not been effective

Private specialists may assess patients with a broader range of conditions, including certain chronic pain, neurological, psychiatric, gastrointestinal and palliative-care needs. However, this does not mean that medical cannabis is automatically suitable or clinically recommended for every person with one of these conditions.

Each patient must be assessed individually. A doctor will normally consider the person’s diagnosis, medical history, previous treatments, current medication and any factors that could increase the risk of adverse effects.

Medical Cannabis for Chronic Pain

Chronic pain is one of the most common reasons people enquire about private medical cannabis treatment. However, NICE does not recommend routinely offering cannabis-based medicinal products for chronic pain in adults unless the treatment forms part of a clinical trial.

Private specialists may still consider an unlicensed product in an individual case, particularly where established treatments have been unsuccessful or unsuitable. Any such decision must be made by the treating clinician rather than by a retailer or non-medical advisor.

Anyone experiencing persistent or unexplained pain should seek advice from a GP or appropriately qualified healthcare professional.

How to Access Medical Cannabis in the UK

There are two principal routes through which a patient may receive medical cannabis in the UK.

NHS Access

NHS access remains limited. A specialist may consider a cannabis-based medicine where there is clear clinical need, suitable evidence and established treatments have not produced an adequate result.

The precise process depends on the patient’s condition, local prescribing arrangements and the medicine being considered. Some cases may require multidisciplinary review or approval through local NHS procedures.

Private Clinic Access

Private clinics provide the majority of medical cannabis prescriptions in the UK. The typical process may include:

Registering with a regulated medical cannabis clinic
Providing medical records and details of previous treatment
Attending an initial consultation with a specialist doctor
Receiving an individual clinical assessment
Having the proposed treatment reviewed where required
Receiving a prescription if the specialist considers treatment appropriate
Obtaining the prescribed product from a registered pharmacy
Attending regular follow-up appointments

Eligibility requirements and fees vary between providers. Patients should review the clinic’s registration, pricing, prescribing process, pharmacy arrangements and ongoing appointment requirements before proceeding.

NHS and Private Prescriptions Compared

Feature	NHS Prescription	Private Prescription
Availability	Limited to a relatively small number of patients	Broader access, subject to specialist assessment
Clinical decision	Made by or under the supervision of an NHS specialist	Made by a specialist working through a private clinic
Cost to patient	Normal NHS prescription arrangements apply	Consultation, follow-up and medication charges normally apply
Product range	Generally restricted by NHS and NICE guidance	May include a wider range of licensed and unlicensed products
Ongoing monitoring	Managed through the relevant NHS service	Usually requires paid follow-up consultations

Can You Buy Medical Cannabis Online?

Medical cannabis can only be obtained legally when it has been prescribed by an authorised clinician and dispensed by a registered pharmacy.

Some legitimate private clinics operate online and provide video consultations. Prescribed medication may then be delivered by their pharmacy. This is different from purchasing products from an unregulated website, social-media account or messaging service.

A website claiming to sell prescription cannabis without a consultation, prescription or regulated pharmacy should be treated with extreme caution.

Never send money to an unknown seller offering controlled cannabis through social media, Telegram, WhatsApp or a similar platform. These transactions may be unlawful and frequently expose customers to fraud, unsafe products or the loss of personal information.

Can Medical Cannabis Patients Drive?

It is illegal to drive while impaired by any drug, including a lawfully prescribed medicine.

UK drug-driving legislation includes specified limits for certain controlled drugs. A statutory medical defence may be available where a medicine has been prescribed, supplied and taken in accordance with professional instructions, provided the driver was not impaired.

A prescription is therefore not permission to drive while affected by cannabis.

Patients should:

Follow the prescribing clinician’s instructions
Read the medicine’s patient information
Avoid driving when sleepy, dizzy, confused or otherwise impaired
Ask their clinician how treatment may affect driving
Keep suitable evidence of their prescription
Check whether their medical condition must be reported to the DVLA

Patients should obtain individual advice from their clinician and the DVLA where necessary.

Employment and Workplace Drug Testing

A prescribed cannabis-based medicine may contain THC and could produce a positive workplace drug-test result.

Employees should review their employer’s drug and alcohol policy and consider discussing prescribed medication with occupational health or an appropriate manager. The correct approach will depend on the role, workplace risks and whether the medication affects the person’s ability to work safely.

Safety-critical roles may be subject to particularly strict rules. Employees should not assume that possession of a prescription removes every workplace restriction or safety obligation.

Can Patients Travel with Medical Cannabis?

Travelling with a controlled medicine can require advance preparation.

Rules vary according to the destination, the medicine, the amount carried and the length of the journey. A UK prescription does not automatically make a cannabis-based medicine lawful in another country.

Patients should speak to their clinic or pharmacy and check the destination country’s requirements before travelling. Supporting documentation, a clinician’s letter or an import permit may be required.

Medication should generally remain in its original pharmacy-labelled packaging. Patients should not travel with medical cannabis until they have confirmed that possession is permitted at their destination and during any connecting journey.

What Is the Difference Between Medical Cannabis and CBD?

Medical cannabis is prescribed for a diagnosed medical need and supplied under the supervision of a healthcare professional. Depending on the prescribed product, it may contain CBD, THC or a combination of cannabinoids.

Consumer CBD products are not prescription medicines unless they have been specifically authorised and supplied as such. They must not be advertised as products that diagnose, treat, prevent or cure a medical condition.

CBD itself is not controlled under the Misuse of Drugs Act. However, THC and several other cannabinoids are controlled substances. A finished consumer product containing controlled cannabinoids must meet the applicable legal requirements, including the conditions associated with an exempt product where relied upon.

The commonly discussed exemption relates to no more than 1mg of controlled drug in the entire container or preparation, alongside other conditions. It is not a general rule allowing a particular percentage of THC in every CBD product.

You can learn more about CBD and the way cannabinoids may occur together in our guide to the CBD entourage effect.

Legal Consumer Cannabinoid Products

Adults interested in non-medicinal cannabinoid products may encounter CBD, CBG and other hemp-derived options. These products occupy a different legal and regulatory category from prescribed medical cannabis.

Consumers should look for clear product information, responsible labelling, batch-specific testing and transparent cannabinoid content. Products should not be selected on the basis of promises to treat pain, anxiety, insomnia or another medical condition.

Weed Supermarket supplies a range of cannabinoid products, including:

These are retail products and are not offered as prescribed medicines or replacements for treatment recommended by a doctor.

Choosing Cannabinoid Products Responsibly

The cannabinoid market can be difficult to navigate. Product names, percentages and descriptions do not always provide enough information to assess quality or compliance.

Before purchasing a product, consider:

Whether the seller clearly identifies the business behind the website
Whether product descriptions avoid unsupported medical claims
Whether cannabinoid and controlled-substance testing is available
Whether the product has clear batch or product information
Whether payment, delivery and customer-service information is transparent
Whether realistic warnings and responsible-use guidance are provided

Details of our approach are available on our UK Compliance and Laboratory Testing page.

Important Considerations Before Using CBD or CBG

CBD and CBG can affect people differently and may interact with prescribed medicines. Anyone who is pregnant, breastfeeding, receiving treatment for a medical condition or taking regular medication should speak to a healthcare professional before using a cannabinoid product.

Particular care may be necessary where medication carries a warning involving grapefruit, liver metabolism, sedation or changes in blood concentration.

Do not stop or alter prescribed medication in order to use a consumer cannabinoid product unless instructed to do so by the clinician responsible for your treatment.

Frequently Asked Questions

Is medical cannabis legal in the UK in 2026?

Yes. A qualifying cannabis-based medicinal product may be possessed and used when it has been lawfully prescribed and supplied. Recreational cannabis, unauthorised supply and home cultivation remain unlawful.

Can my GP prescribe medical cannabis?

A GP cannot normally initiate an unlicensed cannabis-based medicinal product independently. Initial prescribing must be undertaken by an appropriately registered specialist doctor. A GP may sometimes assist with ongoing care under an agreed specialist arrangement.

Do I need to try other treatments first?

Specialists will normally review previous treatments and consider whether established options have been ineffective, unsuitable or poorly tolerated. The precise criteria depend on the condition, available evidence and the clinic or NHS service involved.

Can I get medical cannabis through the NHS?

It is possible, but NHS prescribing remains limited. Cannabis-based medicines are generally considered only for a small number of patients and particular clinical circumstances.

Can I obtain a private prescription?

A private specialist may issue a prescription following a clinical assessment where the doctor considers treatment appropriate. Approval is not automatic and consultation, medication and follow-up charges may apply.

Is CBD the same as medical cannabis?

No. Consumer CBD products are not the same as prescribed medical cannabis. Medical cannabis is prescribed for an individual patient and supplied through a regulated pharmacy. Retail CBD products must not be marketed as medicines unless they have the necessary authorisation.

Is CBD legal in the UK?

Pure CBD is not a controlled drug, but finished products may also contain THC or other controlled cannabinoids. Every product must satisfy the relevant legal and regulatory requirements. The 1mg controlled-drug exemption concerns the whole container or preparation and is subject to additional conditions.

Will CBD make me fail a drug test?

A product containing detectable THC could potentially affect a drug-test result. Labels such as “THC-free” or “non-detectable” should not be treated as an absolute guarantee. Anyone subject to workplace, roadside or sporting drug testing should obtain suitable professional advice before using cannabinoid products.

Can I drive after taking medical cannabis?

You must not drive while impaired. Patients should follow their prescription, speak to their clinician and understand the drug-driving rules. A medical defence may apply in certain circumstances, but it does not protect someone who was unfit to drive.

Can Weed Supermarket advise whether medical cannabis is right for me?

No. We can provide general product and educational information, but we cannot diagnose a condition, assess eligibility for medical cannabis or recommend a treatment. These questions must be discussed with a registered medical professional.

Final Thoughts

Medical cannabis has been legally available in the UK since 2018, but it remains a controlled form of treatment rather than a general retail product. Access through the NHS is restricted, while private treatment requires specialist assessment, a valid prescription and ongoing clinical supervision.

Consumers should clearly distinguish prescribed cannabis-based medicines from non-medicinal CBD, CBG and hemp-derived products. Retail cannabinoid products may form part of an adult’s personal lifestyle choices, but they should not be treated as substitutes for diagnosis, medical advice or prescribed treatment.

Anyone considering medical cannabis should begin by speaking to their GP, existing specialist or a properly regulated medical cannabis clinic. Anyone purchasing a consumer cannabinoid product should prioritise transparent information, responsible descriptions, testing and UK compliance.
