How it works

What legal changes have been made?

On 1st November 2018 the law in the UK was changed regarding medical cannabis. The change was to the Misuse of Drugs regulations 2001. Medical 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 medical cannabis in certain situations).

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

Curaleaf Clinic was the first UK medical cannabis clinic registered by the CQC
