In addition, in June 2018, Home Secretary Sajid Javid announced that the use of medicinal cannabis would be reviewed. He made it clear from the start that this review would not lead to a full legalisation of cannabis, ensuring a clear distinction between recreational use and medicinal applications. The outcome was a strict set of rules that became effective as of the 1st of November. Medicinal cannabis was also moved to a category of drugs (Schedule 2) that is still controlled, but that may be prescribed in certain situations. For example, only specialists in a hospital may issue prescriptions for a limited number of disorders. This concerns children with rare and serious types of epilepsy, adults who are undergoing chemotherapy and adult MS patients. Furthermore, treatment with medicinal cannabis may only start when all the other options have been exhausted, whilst the NHS argues that the treatment method needs to be proven to be effective too. Dr Michael Bloomfield, a leading research fellow in psychiatry at University College London was able to accept this ‘sensible’ approach as, like many other healthcare professionals, he is waiting for scientific evidence. “When we don’t have very strong evidence for any medicine, then it should be hard to prescribe something because we should be prescribing medicines when there’s a very strong evidence base for them”, he told BBC News.
