Project TWENTY21

The independent drug policy charity, ‘Drug Science’ has a registry called, Project TWENTY21 (T21), which is building 'real world' evidence of the effects of Cannabis-Based Medicinal Products (CBMPs).  

It is our hope that by gathering data through Project Twenty21 we can open up access on the NHS in the long term so that medical cannabis can be accessed by more patients across the UK.

Drug Science has linked up with some of the medical cannabis producers  to subsidise the cost of certain CBMPs for patients signing up to the T21 registry.  See the T21 website for more information on costs.  Patients can still have their data included in the registry, even without subsidised CBMPs.

To be included in T21 and eligible for the subsidised CBMPs, patients must commit to having follow up appointments every 3 months, where data will be collected on their condition and well-being using validated questionnaires. 

There are presently 8 medical conditions that are eligible for inclusion in the Project TWENTY21 registry;

Drug Science regularly publishes the data it collects, which continues to inform the academic and political discussion around medical cannabis.  Drug Science is hopeful that further conditions will be added to the registry in due course.


*Cannabis Clinic Cardiff (CCC) specialises in the assessment of Mental Health Disorders.  

At present CCC is able to provide assessments for patients with Anxiety Disorder, Post-Traumatic Stress Disorder, Substance Use Disorder and Attention Deficit Hyperactivity Disorder, all of which would be eligible for enrolment in T21. 


Other mental health disorders may be eligible for an assessment and patients having more than one medical condition should not be put off from having a FREE Eligibility Check, even if they feel one of the above conditions is not their 'Primary' problem.
