NHS vs Private Medical Cannabis in the UK

Medical cannabis has been legal to prescribe in the UK since November 2018, but NHS prescriptions remain exceptionally rare. The vast majority of patients who access cannabis-based medicines in the UK do so through licensed private clinics, staffed by GMC-registered specialists. Understanding the difference between NHS and private routes helps you make an informed decision about your care.

What the NHS Actually Prescribes

Three cannabis-based medicines hold a full UK marketing authorisation and appear on NHS formularies:

• Epidyolex (cannabidiol oral solution) — prescribed for epilepsy associated with Lennox-Gastaut syndrome, Dravet syndrome, and tuberous sclerosis complex in patients aged two and over.
• Sativex (nabiximols oromucosal spray) — prescribed for spasticity associated with multiple sclerosis, subject to local commissioning decisions.
• Nabilone (synthetic cannabinoid capsule) — occasionally prescribed for chemotherapy-induced nausea and vomiting when other treatments have failed.

Outside these three products, NHS prescribing of unlicensed cannabis-based medicines is governed by NHS England guidance that requires specialist sign-off and, in practice, an exceptionally high evidential threshold. As a result, NHS prescriptions for conditions such as chronic pain, PTSD, or anxiety are almost unheard of.

Why Does the NHS Rarely Prescribe Cannabis?

The NHS applies a cost-effectiveness framework overseen by the National Institute for Health and Care Excellence (NICE). For a medicine to receive a positive NICE recommendation, robust randomised controlled trial evidence is typically required. Because cannabis-based medicines have, until recently, been difficult to study in large-scale clinical trials, the evidence base that NICE requires has not yet been established for most conditions.

NHS England guidance also requires that any specialist wishing to initiate an unlicensed cannabis-based medicine must be unable to treat the patient satisfactorily with a licensed product first. This creates a high bar in practice, and most NHS trusts have issued internal guidance making such prescriptions extraordinarily uncommon.

How Private Clinics Fill the Gap

Licensed private cannabis clinics operate under the same legal framework as NHS trusts. They are regulated by the relevant national regulator (CQC in England; equivalent bodies apply in Scotland and Wales), employ GMC-registered doctors, and issue Schedule 2 controlled drug prescriptions that are dispensed by Home Office-licensed pharmacies. The prescription itself carries the same legal weight as any NHS controlled drug prescription.

Clinics listed in our clinic directory conduct thorough initial consultations, review your medical history and previous treatments, and prescribe only where clinically appropriate. Patients must typically demonstrate that they have tried conventional treatments without adequate benefit.

Cost Comparison

NHS prescriptions, where issued, are subject to the standard NHS prescription charge (or are free for eligible patients). Private cannabis prescriptions carry the full cost of the medicine, which typically ranges from approximately £100 to £400 per month, plus separate consultation fees. There is no mechanism to reclaim private cannabis prescription costs through the NHS.

Some private health insurers are beginning to review their position on cannabis-based medicines, but coverage remains limited and policy-dependent. Patients should verify their own insurance terms before committing to treatment. See our dedicated guide on medical cannabis costs in the UK for a full breakdown.

Clinical Quality: Is Private Care Inferior?

A reasonable concern for any patient is whether private care is as rigorous as NHS care. In the case of medical cannabis clinics, the clinical standards are set by the same regulatory bodies. GMC registration is mandatory for prescribing doctors, registration with the relevant national regulator governs clinic operations, and Home Office licensing covers dispensing pharmacies.

That said, quality varies between clinics. A reputable clinic will conduct a thorough clinical assessment, maintain communication with your NHS GP, review your progress at regular intervals, and prescribe within evidence-based parameters.

Returning to Your NHS GP After a Private Prescription

Your NHS GP is not obligated to take over prescribing of a private cannabis medicine. However, your GP remains your primary care provider for all other aspects of your health, and a reputable private clinic will send a clinical summary to your GP after your initial consultation.

If you decide to stop private cannabis treatment, you can simply cease your subscription. Your GP relationship is unaffected. You should always inform your GP of all medicines you are taking, including privately prescribed cannabis-based medicines, to ensure your overall care record is accurate.

Frequently Asked Questions

Is a private medical cannabis prescription a real prescription?

Yes. Private medical cannabis prescriptions are issued under the Misuse of Drugs Regulations 2001 (Schedule 2) by GMC-registered specialists. They are legally equivalent to any other controlled drug prescription and are dispensed by Home Office-licensed pharmacies.

Can my NHS GP prescribe medical cannabis?

In theory, yes — but in practice, almost never. NHS guidance restricts cannabis prescribing to specialist clinicians, and even then the evidential requirements mean NHS prescriptions outside the three licensed products (Epidyolex, Sativex, Nabilone) are extremely rare.

Will starting a private cannabis prescription affect my NHS treatment?

Your NHS GP cannot be compelled to take over cannabis prescribing, but your wider NHS care remains unaffected. Reputable clinics notify your GP of your treatment. You should always inform your GP of all medicines you are taking.

How much does private medical cannabis cost per month?

Costs vary considerably depending on the product and quantity. Most patients pay between £100 and £400 per month for the medicine itself, plus initial and follow-up consultation fees charged separately by the clinic.

Is private medical cannabis covered by health insurance?

Coverage is limited and varies by insurer and policy. Most standard UK private health insurance policies do not currently cover cannabis-based medicines. Check your policy documents or contact your insurer directly before assuming coverage.
