Access Medical Cannabis with Project Twenty21

Project Twenty21 is the largest observational medical cannabis study in the UK, gathering data on the efficacy of cannabis-based medicines for a wide range of conditions. 

Why join Project Twenty21?

You help us move closer to our ultimate goal of access to medical cannabis on the NHS by providing us with your data. We do this by asking patients to fill out a few questionnaires once every 3 months.

You’re in safe hands, with some of the UK’s leading medical cannabis clinicians prescribing at our participating clinics.

You can trust that your prescribed product will be high quality, as the study is supported by multiple industry partners offering EU GMP-certified products.

Drug Science is completely independent and observational, so there is no bias when it comes to which clinic you choose or what you will be prescribed.

We have worked with the licensed-producers to offer competitive prices on all Twenty21 products.

How can I get medical cannabis with Project Twenty21?

Medical cannabis treatment starts with a private consultation between you and a specialist doctor from a Project Twenty21-approved cannabis clinic

During the consultation, your doctor will be happy to discuss any medical cannabis treatment which suits your needs.

Once your prescription has been approved, the pharmacy will contact you for payment before your medication is sent to your house.
