Can My GP Prescribe Medical Cannabis?

The Current Legal Position

• GPs in the UK cannot initiate a medical cannabis prescription under current NICE guidance and NHS policy
• Prescribing CBMPs is restricted to specialist doctors on the GMC Specialist Register
• GPs may co-prescribe or manage ongoing prescriptions in exceptional cases where a specialist has initiated treatment, but this is rare in practice
• This restriction is in place due to the complexity of cannabis-based prescribing and the current gaps in GP training on this topic

The restriction to specialists frustrates many patients who have long-established relationships with their GP and find the private clinic route financially challenging. This is an active area of policy debate in UK healthcare.

Why GPs Cannot Prescribe Medical Cannabis

• The NICE guideline framework for most cannabis-based medicines does not recommend routine commissioning via primary care
• The Misuse of Drugs Regulations require that Schedule 2 CBMPs are prescribed by clinicians with appropriate specialist knowledge
• Most GP training programmes do not yet include comprehensive medical cannabis pharmacology or prescribing guidance
• Liability concerns around prescribing a drug with a complex evidence base and significant variability in patient response also play a role

The situation may evolve. As the evidence base grows and training programmes develop, there is a plausible future in which GPs play a greater role in ongoing management of stable cannabis patients initiated by specialists.

What Your GP Can Do

• Refer you to a specialist who can assess your eligibility — ask specifically for a pain consultant, neurologist or psychiatrist depending on your condition
• Provide a GP summary letter outlining your medical history, diagnoses and prior treatments — essential for a private cannabis clinic assessment
• Monitor for drug interactions if you add cannabis to existing medications
• Take over ongoing management of a stable prescription in exceptional cases if a specialist supports this

Your GP is a useful ally in the process even if they cannot write the prescription. A well-written GP referral letter that clearly documents treatment history significantly strengthens your case at a specialist assessment.

What to Tell Your GP

• Be honest about why you are seeking a medical cannabis assessment — there is nothing to hide; it is a legal treatment
• Ask whether they can refer you through NHS channels (very limited but worth asking)
• Ask for a printed medical summary or records download that you can upload to a private clinic
• Discuss whether any of your current medications interact with cannabinoids so the specialist has that information upfront

Most GPs are supportive of patients exploring evidence-based treatments, even those they cannot prescribe themselves. A non-judgmental, informative conversation with your GP before attending a cannabis clinic is almost always worthwhile.
