Medical cannabis is legal now is what many UK patients hear; what they are not told is how hard it can be to work out if they actually qualify. A private cannabis prescription in the UK only becomes an option after two standard treatments have failed to bring enough relief and a specialist believes cannabis‑based medicines may safely help.
This article focuses on what that really means in practice so you can see, in plain English, whether medical cannabis might be a realistic option for your situation.
Key takeaways
By the end of this guide, you will:
- Understand the difference between NHS and private medical cannabis routes.
- Know the core criteria specialists use to assess eligibility.
- See each step of the private prescription pathway, from enquiry to follow up.
Next, let’s look at who can legally prescribe medical cannabis in the UK and where your GP fits in.
Who can legally prescribe medical cannabis in the UK?
The GPs in the UK cannot start medical cannabis treatment; only doctors on the GMC Specialist Register can initiate prescriptions, whether in NHS hospitals or private clinics. Your GP’s role is usually to provide your medical records, share information about past treatments, and sometimes take part in shared‑care arrangements, but they are not the person who decides if you begin medical cannabis.
Decisions about medical cannabis eligibility inside the UK are made by specialist doctors who review your diagnosis, treatment history, current medicines, and overall health, and then weigh potential benefits against risks for your individual situation.
Can doctors prescribe CBD in the UK?
People often ask if doctors prescribe CBD, and the answer depends on what you mean by CBD. Certain licensed CBD‑containing medicines, such as those used for specific severe epilepsies or MS‑related symptoms, can be prescribed by specialists for tightly defined conditions, while shop‑bought CBD oils are treated as supplements rather than prescribed medicines and are not usually written on a prescription.
Medical cannabis eligibility in the UK: what it usually involves
When clinicians talk about medical cannabis eligibility, they mean a set of safety and evidence‑based checks, not a judgement about how much you are “suffering” or whether you deserve help. Eligibility is considered only when symptoms remain troublesome despite appropriate standard treatments and when there are no serious medical red flags that would make cannabis‑based medicines unsafe.
In most clinics, doctors look for:
- A confirmed diagnosis from a suitable healthcare professional.
- Symptoms that significantly affect day‑to‑day life, work, sleep, or relationships.
- At least two guideline‑recommended treatments tried, not tolerated, or ineffective.
- No major contraindications, such as certain severe mental health or cardiac conditions.
In practice, medical cannabis eligibility for the UK is about whether a specialist believes cannabis‑based medicines are likely to help you more than they could harm you, based on your individual history and current health.
Qualifying conditions: NHS versus private reality
To understand who qualifies for medical cannabis in the UK, it is useful to compare the strict NHS criteria with the broader but still specialist‑led assessments offered in private clinics.
What the NHS considers
On the NHS, cannabis‑based medicines are only considered for a few situations when standard options have not worked. These are certain rare, treatment‑resistant epilepsies, multiple sclerosis‑related muscle stiffness and spasms, and chemotherapy‑related nausea and vomiting that do not respond to usual anti‑sickness medicines. Even then, decisions sit with hospital specialists, not GPs.
Did you know?
An FOI analysis reported by Cannabis Health News found that, between November 2018 and July 2022, more than 89,000 private medical cannabis prescriptions were issued in the UK, compared with fewer than five comparable NHS prescriptions for unlicensed cannabis‑based medicines in the same period.
What private clinics commonly see
In private practice, specialists may assess a wider range of conditions but still decide carefully case by case. These often include:
- Long‑term pain, such as neuropathic pain, arthritis, and fibromyalgia.
- Neurological conditions including MS, epilepsy, migraine and Parkinson’s disease.
- Mental health and sleep issues like anxiety, PTSD, some mood disorders, and insomnia, with extra screening.
- Gastrointestinal and other conditions where symptoms continue despite standard care.
These patterns can help you understand how medical cannabis eligibility is applied in real clinics, but they do not guarantee a prescription for any specific diagnosis. In private clinics, decisions about a private cannabis prescription are still made case by case, because specialists must balance potential benefit against safety, legal duties and current evidence for each person.
How a private cannabis prescription in the UK is issued: step by step
If you are considering a private cannabis prescription in the UK, it helps to understand each step before you book an appointment so you know what to expect and what you will need to prepare.
1. Initial enquiry or online self‑assessment
You usually start by completing a short online form or enquiry, sharing your main diagnosis, symptoms, and treatments you have already tried.
2. Sharing GP letters and medical records
The clinic then asks for GP summaries or hospital letters so the specialist can confirm your diagnosis and review which medicines and therapies have been used so far, and how well they worked or were tolerated.
3. Specialist consultation
You meet a doctor on the GMC Specialist Register, often by video. Together you discuss your symptoms, day‑to‑day impact, mental health history, current medicines, and what you hope medical cannabis might change.
4. Specialist decision
The doctor decides whether medical cannabis is appropriate now, whether more information or tests are needed, or whether it is not suitable and why. If appropriate, they recommend a starting product and dose based on your condition and risk profile.
5. Prescription and follow‑up
The prescription is sent to a partner pharmacy, which dispenses and delivers your medication. Follow‑up appointments are arranged to review benefits, side effects, and whether any dose or product changes are needed, keeping treatment as safe and effective as possible.
At each stage, your specialist is checking that medical cannabis remains a safe, proportionate option in line with your goals and any new information.
When you may not be eligible (and why)
Some situations make medical cannabis more risky or unsuitable, even when symptoms are severe. This can include a history of psychosis or certain severe mental health conditions, active substance dependence, pregnancy or breastfeeding, and some uncontrolled heart or other serious medical problems. These safety factors are a key reason why medical cannabis eligibility is not automatic, even if your condition appears on common lists of qualifying conditions.
Sharing an honest, full history with your clinician helps them decide safely and recommend other options if cannabis‑based medicines are not right for you.
Your checklist to decide whether to pursue a private cannabis prescription
Before you commit to pursuing a private cannabis prescription in the UK, it can help to reflect on a few key questions rather than feeling pushed into a decision. Ask yourself:
- Have I tried guideline‑recommended treatments for my condition, and what actually happened?
- Which symptoms do I most want to change, and how would I measure real improvement?
- Can I realistically afford private consultations and prescriptions if the NHS cannot offer this option?
Ready to check your eligibility?
If you would like a specialist to review your situation and see whether a private cannabis prescription might be appropriate, you do not have to work that out on your own. A short eligibility assessment with the Leafease clinical team allows a GMC‑registered doctor to look at your diagnosis, past treatments and current health, then give you a clear, personalised view on whether medical cannabis is likely to be a safe, realistic option for you and what your next steps could be.
