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 (cannabidium).

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 The NHS lists the following conditions where cannabis-based medicines may be prescribed: Chronic pain — including neuropathic pain, fibromyalgia, and pain that has not responded to at least two conventional treatments Severe epilepsy — including Dravet syndrome and Lennox-Gastaut syndrome Multiple sclerosis spasticity — where other treatments have not been effective Cancer-related symptoms — including pain, nausea, and loss of appetite Inflammatory conditions — such as Crohn's disease and ulcerative colitis Mental health conditions — including PTSD, anxiety, and insomnia in certain circumstances In private clinics, doctors assess each patient individually and may prescribe for conditions beyond the NHS list, including chronic pain, anxiety, depression, ADHD, endometriosis, migraines, and insomnia.

The key criterion is that conventional treatments have been tried and have not provided adequate relief.

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.

It does not guarantee approval but gives you an idea of whether a consultation is worth pursuing.

Step 2: Book a Consultation If eligible, you book an initial consultation with a specialist.

This is a video call lasting 30-60 minutes where the doctor will review your medical history, discuss your symptoms, and assess whether medical cannabis is appropriate.

You will typically need: Your NHS number and basic medical history Details of previous treatments and medications Any specialist letters or medical records (clinics can often 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 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? Medical cannabis is not available on the NHS for most patients.

All costs are private and include: Initial consultation: £0 (free eligibility) to £299 Follow-up consultations: £29 to £100 every 3 months Monthly medication: £80 to £300 depending on product and dosage A full year of treatment typically costs between £1,200 and £4,000 including consultations and medication.

Some clinics offer access schemes for patients on benefits or veterans.

Mamedica offers free consultations for life to patients on PIP, DLA, or Universal Credit, and to veterans.

CB1 Medical charges £50 upfront for all consultations for 12 months.

Cantourage 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 under the tongue, 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.
