Medical Cannabis Research in UK - Project Twenty21

Updated: Jul 6, 2020


Cellen is a research driven organisation aiming to improve the health and wellbeing of people living with chronic conditions in the UK. Our NHS experts and researchers are committed to being led by evidence, and we support the call for more evidence on the efficicy of medical cannabis from leading authorities such as Royal College of Psychiatrists.

This is why we are proud to be a founding partner in Project Twenty21: a registry that will monitor 20,000 patients taking Medical Cannabis over a 2 year period. The project is led by Professor David Nutt and Drug Science. This will be the largest body of evidence on cannabis in Europe and has brought together leading drug science experts to understand the medical use of cannabis in this large cohort. 

We are excited that beta testing has begun. We believe that this is an important milestone for access to Medical Cannabis in the UK. As a science and research led organisation, our primary objective is to ensure that clinicians have the evidence base required to effectively prescribe.
