Despite medical cannabis now being legal on the NHS, a limited number of prescriptions have been granted since the law change and some parents are having to pay thousands for import licences and private prescriptions. An NHS England review has blamed the lack of prescriptions on concerns about both the potential harm to mental health and effectiveness of medical cannabis. It said more clinical trials need to be carried out and a "UK-wide paediatric specialist clinical network" should be created to help “very cautious” doctors, by providing expert advice on complex cases. The "forward-looking and positive review" was welcomed by the Medical Cannabis Clinicians Society (MCCC), whose executive director Hannah Deacon spoke to ITV News about the issue. Her eight-year-old son Alfie Dingley, who suffers from severe epilepsy, was the first of a handful of patients in the UK to receive an NHS prescription for medical cannabis, despite rule changes last year allowing doctors to prescribe it.
