Medical Cannabis Doctors

Our aim is to be trusted by healthcare professionals to enable us to support patients in a safe, responsive, reliable and effective way.

By Doctors for Healthcare Professionals to help patients

Sapphire Medical Clinics is formed by doctors. We aim to become a trusted partner of NHS medical professionals and support patients in using medicinal cannabis where other treatments have failed.

Our internationally renowned and respected consultants will assess patients within their area of expertise and if another conventional therapy is available that will be tried first.

Rigorous Prescribing Framework

There are three mechanisms by which Patients and their Healthcare Professionals are reassured that the highest standard of clinical practice and prescribing are upheld. These are:

1. All clinicians are trained to the highest level by international experts with experience in medicinal cannabis prescribing.

2. All clinicians receive bespoke and disease specific clinical and prescribing guidelines developed by Sapphire Medical Clinics using large data sets.

3. Following consultation, all patients are discussed at the central multidisciplinary team meeting involving all the clinicians.

Our Doctors

All of our doctors have been through an intense training program to equip them with the skills required to prescribe this very complex and variable medicine. The program includes face-to-face sessions with an expert cannabis physician, telemedicine clinics with an experienced cannabis counsellor.

Healthcare Professionals

For all UK medical professionals wishing to learn more about medicinal cannabis, we have put together a series of online modules (with examinations) which is the only free CPD certified content in UK.

Why we are safe

We have followed the guidance set by the GMC, MHRA, NHS England.

We have gone beyond this guidance to create our own rigorous Standard Operating Procedures, which are being ratified by the above organisations and will be published on our site in due course. This will guide the future use of medicinal cannabis by closely monitoring adverse events and change in patient outcomes.

We have recruited experienced NHS consultants who are experts in their fields and will only see patients who they would see in their practice in the NHS.

We are aligned to the most up to date research and will continually monitor any new developments.

We will collect data on all of our patients with their consent and will form the first UK registry on medicinal cannabis. This will guide the future use of cannabis, adverse reactions and change in patient outcome to establish where this drug is of most use.

Multidisciplinary Team

This is formed of our seven specialist doctors and the doctors within the clinic. After the initial consult, if deemed appropriate the patient is discussed at the MDT and a final decision is made to issue a prescription or not.


Our team have already excelled in their careers individually and now have come together to offer the best, most responsible, expert led clinical assessment for medicinal cannabis.

Hassle Free Prescriptions

Once the prescription has been written the doctor has no further part in the payment or delivery of the medicine. Sapphire will organise this entirely to maintain the patient doctor relationship and ensure the prescription is fulfilled.
