Leadership & Management Team

Doctor Training

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 and online modules (with examinations) which are due to be accredited in Canada and the UK

Intense Treatment

Our patients have a ‘Patients Know Best’ account created for them once they have been referred to our clinic.

This gives them access to all of their medical information for their medicinal cannabis treatment. It also allows them to use our uniquely designed symptom checker to report any change in condition since starting treatment with medicinal cannabis and allows us to keep track of doses.

Follow-up procedures will ensure a high level of pharmacovigilance and surveillance with immediate reporting of adverse events to a national database.

Structure Of The Clinic


As a patient you will be referred from your GP or hospital consultant for a clinical assessment on your condition and whether you may benefit from medicinal cannabis.


Each patient will be assessed by one of our expert consultants in the area of your illness. The consultation will last 40 minutes. There will be no incentives for doctors to approve cannabis prescriptions.


Every prescription will be agreed upon by our Multidisciplinary Team and signed off by our Medical Director. We will endeavour to deliver the medicine to the patient without delay, via our partners.

What legal changes have been made?

On 1st November 2018 the law in the UK was changed regarding medicinal cannabis. The change was to the Misuse of Drugs regulations 2001. Medicinal cannabis was re-scheduled from a schedule 1 drug (this means of no medical benefit) to a schedule 2 drug (this allows doctors to prescribe medicinal cannabis in certain situations).

In practice this means that some patients who have exhausted conventional therapies are able to receive a prescription for medicinal cannabis. Only doctors on the specialist register of the GMC are authorised to prescribe medicinal cannabis and satisfy the the guidelines issued by GMC, NHS England and MHRA.
