The Complete Guide to Medical Cannabis in the UK 2026: How to Get a Prescription

Medical cannabis has been legal in the UK since 1 November 2018, when the Misuse of Drugs Act was amended to allow specialist doctors to prescribe cannabis-based products. Despite this, access remains almost entirely private — NHS prescriptions are extremely rare — and most patients don't know where to start.

This guide covers everything you need to know about accessing medical cannabis in the UK in 2026.

What is Medical Cannabis?

Medical cannabis refers to cannabis-based products prescribed by a specialist doctor for a diagnosed medical condition. It is not the same as over-the-counter CBD oil, which is sold as a food supplement and contains minimal therapeutic levels of active compounds.

The two main active components are THC (tetrahydrocannabinol) and CBD (cannabidiol). THC is psychoactive and produces the 'high' associated with recreational cannabis. Medical cannabis products contain regulated levels of these compounds and are prescribed for specific therapeutic purposes.

Is Medical Cannabis Legal in the UK?

Yes. Since November 2018, specialist doctors on the GMC Specialist Register can legally prescribe cannabis-based products for medicinal use. The prescription must be made by a specialist — not a GP — and the product must be a licensed medicine or a "specials" product imported under a valid import licence.

Recreational cannabis remains illegal. The law only permits medical use under the supervision of a specialist doctor.

Qualifying Conditions for Medical Cannabis in the UK

In the private sector, doctors assess each patient individually. The key criterion is that at least two conventional treatments have been tried and have not provided adequate relief. Common approved conditions include:

• Chronic Pain: Neuropathic pain, fibromyalgia, arthritis, and back pain.
• Mental Health Conditions: PTSD, anxiety, depression, and ADHD.
• Neurological Conditions: Multiple sclerosis spasticity, epilepsy, and Tourette's syndrome.
• Gastrointestinal Disorders: Crohn's disease, ulcerative colitis, and IBS.
• Cancer-Related Symptoms: Pain, nausea, and loss of appetite.

How to Get a Medical Cannabis Prescription in the UK

Step 1: Check Your Eligibility

Most UK medical cannabis clinics offer a free eligibility check — a short online questionnaire that takes 2-5 minutes. This asks about your condition, symptoms, and previous treatments.

Step 2: Book a Consultation

If eligible, you book an initial consultation with a specialist. Many private UK clinics operate entirely online. For budget-conscious patients, Alternaleaf offers consultations from £49, while patients with complex medical histories often prefer premium pain-specialist clinics like Integro Clinics. This is a video call lasting 30-60 minutes where the doctor will review your medical history. You will typically need to provide:

• Your NHS number and basic medical history.
• Details of previous treatments and medications.
• Your GP Summary of Care Record (clinics can request these from your GP directly).

Step 3: Receive Your Prescription

If approved, your prescription is sent electronically to a dispensing pharmacy. You will receive your medication by post within 5-10 working days. Repeat prescriptions can be requested through the clinic's patient portal between follow-up appointments.

How Much Does Medical Cannabis Cost in the UK?

Because medical cannabis is not available on the NHS for most patients, all costs are private. Expect to pay:

Cost Item	Price Range	Frequency
Initial Consultation	£0 – £299	One-off
Follow-up Consultations	£29 – £100	Every 3 months
Monthly Medication	£80 – £300	Monthly (depends on dose)

A full year of treatment typically costs between £1,200 and £4,000 including consultations and medication.

• Can Clinic: Offers free consultations to veterans via their partnership with Combat Stress.

What Products Are Available?

UK specialist clinics can prescribe cannabis-based products for medicinal use (CBPMs), which include:

• Dried cannabis flower: Vaporised, typically 5-30g per month, priced from £5 per gram.
• Cannabis oil: Taken sublingually, priced from £40-150 per bottle.
• Cannabis capsules: Taken orally, priced similarly to oils.
• Vape cartridges: For patients who prefer inhalation.

Products are sourced from licensed UK producers and imported from EU-GMP certified facilities in Canada, the Netherlands, Germany, and other countries.

Can You Get Medical Cannabis on the NHS?

Technically yes, but in practice it is extremely rare. Since legalisation, only a handful of NHS prescriptions have been issued. The NHS has only approved cannabis-based medicines for a narrow set of conditions — primarily severe epilepsy in children, spasticity in MS, and nausea from chemotherapy.

Most patients who want medical cannabis in the UK pay privately. This is why over 30 private clinics have emerged since 2019 to serve the demand that the NHS is not meeting.

Driving and Medical Cannabis

Medical cannabis patients are subject to the same road traffic laws as any other driver. If you are taking medication that impairs your ability to drive, you should not drive. THC can remain in the bloodstream for days after use, and roadside drug tests can detect it.

If you are taking medical cannabis and are unsure about driving, speak to your prescriber. The Cannabis Industry Council has published guidance for patients on driving with a medical cannabis prescription.

• Your specific condition — some clinics specialise in certain conditions.
• Consultation costs and follow-up pricing.
