Getting a Medical Cannabis Prescription in the UK
Medical cannabis has been legal in the UK since November 2018, but many patients still find the process confusing. This guide walks you through every step — from checking eligibility to your first prescription.
Who Can Be Prescribed Medical Cannabis?
Medical cannabis is available to patients with a range of conditions. Unlike common belief, there is no fixed list of qualifying conditions. A specialist doctor (consultant) can prescribe cannabis-based medicines if:
- You have tried at least two conventional treatments without adequate benefit
- The potential benefits outweigh the risks for your specific condition
- A licensed specialist in your condition agrees to prescribe
- You are over 18 (some exceptions for children with epilepsy)
Most Common Qualifying Conditions
- Chronic pain (back pain, fibromyalgia, nerve pain, arthritis)
- Multiple sclerosis (MS) — muscle spasticity and pain
- Post-traumatic stress disorder (PTSD)
- Anxiety disorders
- Insomnia and sleep disorders
- Cancer-related pain and nausea
- Epilepsy (especially treatment-resistant)
- Crohn's disease and inflammatory bowel disease
Step-by-Step: Getting Your Prescription
Step 1: Check Your Eligibility
Before booking, review your medical history. Most clinics require evidence that you have tried at least two conventional treatments. Gather your GP records, prescription history, and any specialist letters. This significantly speeds up the process.
Step 2: Choose a Clinic
The UK has over 20 licensed medical cannabis clinics. Prices and specialties vary considerably. Some key differences:
- Consultation fees: Range from £0 (Mamedica) to £199 (Sapphire)
- Repeat prescription fees: £0 to £99 per month
- Specialist focus: Some clinics specialise in pain, others in mental health
- Delivery speed: Most deliver within 3–5 working days
Step 3: Book Your Initial Consultation
All consultations happen via video call with a specialist doctor. You will need to provide:
- Photo ID (passport or driving licence)
- GP medical records (most clinics help you obtain these)
- List of previous treatments and medications
- Description of your condition and symptoms
Step 4: The Consultation
Your consultation typically lasts 30–45 minutes. The specialist will review your history, ask about your symptoms, and discuss whether cannabis-based medicine is appropriate. If approved, they will suggest suitable products — usually starting with an oil or a lower-THC flower.
Step 5: Your Prescription
If approved, your prescription is sent directly to a licensed pharmacy (usually Sapphire, Dispensary Green, or another partner pharmacy). Your medicine is then dispensed and posted to you in discreet packaging. Most patients receive their first prescription within 5–7 days of approval.
How Much Does It Cost?
The total monthly cost depends on your clinic, product, and dosage. A rough breakdown:
- Initial consultation: £0–£199 (one-off)
- Monthly prescription review: £0–£99
- Medicine (flower, 10g): £50–£180 depending on product and clinic
- Medicine (oil, 10ml): £40–£120
Total monthly cost for most patients: £80–£250. Using a price comparison tool like LeafMe can save you £30–£80 per month on the same products.
Can My GP Prescribe Medical Cannabis?
Currently, only specialist consultants (not GPs) can initiate medical cannabis prescriptions in the UK. Once established, a GP may be able to continue prescribing, but in practice almost all UK medical cannabis prescriptions come through private specialist clinics. The NHS rarely prescribes cannabis-based medicines outside of specific drugs like Epidyolex (for epilepsy) and Sativex (for MS spasticity).
What Happens After Your First Prescription?
Most patients have a follow-up appointment after 4–8 weeks to assess how the medicine is working. Dosage, product, or strain may be adjusted. Once stable, many clinics offer monthly repeat prescriptions with minimal appointments.
Tips for New Patients
- Request your medical records from your GP before booking — this saves weeks
- Keep a symptom diary for 2–4 weeks before your consultation
- Be honest about previous cannabis use — it does not disqualify you
- Ask your clinic whether they can access your NHS records directly (many can)
- Compare medicine prices across clinics — the same product can vary by 40%
Frequently Asked Questions
Is medical cannabis the same as recreational cannabis?
No. Medical cannabis in the UK is grown to pharmaceutical standards, precisely dosed, and supplied by licensed manufacturers. It is legal under a valid prescription and subject to strict quality controls.
Will I fail a drug test?
Possibly. Most THC-containing medical cannabis products will show up on standard drug tests. Always carry your prescription if you drive or work in a safety-critical role. Discuss this with your clinic before starting.
Can I drive while taking medical cannabis?
This is a complex area. Having a prescription does not exempt you from drug driving laws. If a roadside test detects THC above the legal limit, you could face prosecution. Many patients with a valid prescription use CBD-dominant products during the day and THC products only at night. Always seek legal advice if unsure.
