About medical cannabis

Yes. Medical cannabis was made legal on 1 November 2018 and provided it is prescribed by a medical specialist who has taken into account the current evidence and guidelines and come to a decision that is in your best interest, it is legal to prescribe and for patients to take.

Medical cannabis can be used for symptom relief in a variety of conditions where other first-line medications and conventional drugs have failed, such as in many types of chronic pain conditions, neuropathic pain, and psychiatric conditions.


If you are unsure if you are a good candidate and feel you may benefit from medical cannabis, you have two options. You can see your own GP or specialist to discuss a referral to The Medical Cannabis Clinic for treatment. Or, you can make an appointment with Dr Leon Barron, who can assess patients who are exploring this option. If you do not have a referral letter from your physician, Dr Barron can assess your case to see whether medical cannabis is right for you.

CBD oils found without a prescription in the UK and Europe are made from industrial hemp. Industrial hemp is strains of the cannabis plant that have been cloned and bred to remove the THC to less than 0.2%. These products vary in cost and quality and are not regulated as medication so we do not recommend their use for medicinal purposes.

Medical cannabis that contains higher amounts of THC carry a small risk of habituation and addiction if used daily for chronic use, but the risk is lower than with other classes of medications such as opioid pain medications and possibly lower than benzodiazepines for anxiety and sleep. Your medical cannabis specialist will monitor you closely for signs of addiction to minimize this risk and choose specific products with lower risk appropriate for your symptoms.

Our GMC registered specialists are experts in using medical cannabis and will choose your cannabis medicine care plan products after a comprehensive assessment including the main symptoms targeted, current medications, the pattern of your symptoms and lifestyle factors such as doing any safety-sensitive jobs. They will also monitor and adjust the medication on a regular basis to ensure the best effect with fewest side effects.

We hope that medical cannabis will soon become available for patients on the NHS. Although medical cannabis was legalised in the UK last year, only a handful of patients have secured NHS prescriptions due to multiple barriers. The Medical Cannabis Clinics enable appropriate access to treatment for people with high unmet needs who are currently unable to access the treatment on the NHS.

Becoming a patient

Many medical cannabis products contain only trace amounts of THC, the chemical in the plant responsible for making people feel high and for many indications it is not necessary to have significant amounts of THC to achieve symptom relief. The goal of medical cannabis therapy is to provide symptom relief while minimizing potential psycho-activity, which is very different than smoking cannabis recreationally, normally high in THC and cultivated to produce a high feeling.

We recommend that you speak with your insurance company to confirm whether your plan will cover the costs.

A referral letter allows The Medical Cannabis Clinic specialist to understand more about your condition, symptoms and treatment history from your specialist consultant, GP or other healthcare professionals involved in your care.


If you do not have a referral letter, you will be asked to complete the questionnaire and return it to us along with a 10-year medical summary, the results of any recent blood tests and any letters from specialists overseeing your care. Patients can obtain this information from their GP and specialists.

We will then contact you to discuss an appointment with our GP.

Treatments and prescriptions

This will vary depending on the specific prescription – some may be delivered the next day. Other prescriptions could take up to 28 days.

If you have a letter of referral then please bring it to your appointment together with any details of existing or previous medication taken for your current condition.
