Key fact: As of 2025, more than 75,000 patients in the UK hold a valid medical cannabis prescription. The number is growing every month as awareness and access improve.
What Is Medical Cannabis?
Medical cannabis refers to cannabis-based medicinal products (CBMPs) prescribed by a specialist doctor to treat specific health conditions. In the UK, CBMPs have been legal to prescribe since November 2018, when the government rescheduled them from Schedule 1 to Schedule 2 controlled drugs.
Unlike recreational cannabis, medical cannabis is produced to pharmaceutical standards. It is dispensed by a GPhC-registered pharmacy — such as Medcann Pharmacy — and must be prescribed by a specialist clinician on the General Medical Council (GMC) register.
| Product Type | How It Is Used | Common Uses |
|---|---|---|
| Dried flower (herbal) | Vaporised — never smoked | Chronic pain, PTSD, sleep disorders |
| Oil (sublingual) | Drops under the tongue | Anxiety, epilepsy, nausea |
| Capsules | Swallowed like a tablet | Consistent dosing, chronic conditions |
| Vape cartridge | Inhaled via medical vaporiser | Fast-acting relief, pain, anxiety |
Is Medical Cannabis Legal in the UK?
Yes. Medical cannabis is fully legal in the UK when prescribed by a specialist doctor. The Misuse of Drugs (Amendments) (Cannabis and Licence Fees) (England, Wales and Scotland) Regulations 2018 created a legal route for CBMPs to be prescribed and dispensed.
Important rules to understand:
- Only a specialist doctor (not a GP) can prescribe CBMPs in most cases.
- The prescription must be dispensed by a licensed pharmacy.
- UK law sets a blood THC limit of 2μg/L for drivers. Patients with a valid prescription have a statutory medical defence — but only if they are not impaired.
- Travelling abroad with medical cannabis requires advance planning. Most countries do not recognise UK prescriptions.
Who Is Eligible for Medical Cannabis in the UK?
Eligibility is assessed on a case-by-case basis by a specialist clinician. There is no single approved list of conditions, but CBMPs are most commonly prescribed for the following:
In most cases, a clinician will want to see evidence that you have already tried at least two conventional medications for your condition without adequate relief. This is known as the "treatment-resistant" pathway. Read our full eligibility guide →

How Much Does Medical Cannabis Cost in the UK?
Cost is one of the most common questions patients ask. The NHS does not routinely fund medical cannabis prescriptions, so most patients pay privately. Here is a realistic breakdown:

|---|---|
| Initial consultation | £200 |
| Follow-up appointments | £95 per quarter |
| Monthly prescription (flower) | £100 – £350 per month |
| Monthly prescription (oil) | £80 – £250 per month |
| Annual total (approximate) | £1,500 – £5,000+ |

Full 2025 pricing guideWhat Are CBMPs? Understanding the Products
CBPM stands for cannabis-based product for medicinal use. Under UK law, a product is classified as a CBPM if it is or contains cannabis, is produced for medicinal use in humans, and is a medicinal product or ingredient of a medicinal product.
The two most clinically significant compounds are THC (tetrahydrocannabinol) — the psychoactive compound responsible for pain relief, appetite stimulation, and sleep improvement — and CBD (cannabidiol) — a non-psychoactive compound with anti-inflammatory, anxiolytic, and anti-epileptic properties.

Updated March 2026Frequently Asked Questions
Can my GP prescribe medical cannabis?
In most cases, no. CBMPs must be prescribed by a specialist doctor on the GMC Specialist Register. Most patients access medical cannabis through a specialist clinic or pharmacy like Medcann.
Will medical cannabis show up on a drug test?
Yes. THC can be detected in urine for days to weeks after use, depending on frequency and dose. If you are subject to workplace drug testing, discuss this with your clinician before starting treatment.
Can I travel abroad with my prescription?
This depends on your destination. Many countries do not recognise UK medical cannabis prescriptions. Always check the laws of your destination country and carry a travel letter from your prescribing clinician.
Is medical cannabis addictive?
Like many medicines, CBMPs carry a risk of dependence with long-term use, particularly products with higher THC content. Your clinician will monitor your treatment and discuss any risks with you.
How long does it take to feel the effects?
Inhaled products (flower, vape) act within minutes. Oils typically take 30–90 minutes. Capsules can take 1–2 hours. Your clinician will guide you on the best product for your needs.
