Trial to test if cannabis-based mouth spray can treat brain tumours

First such study in the world aims to find out if Sativex combined with chemotherapy can help treat glioblastoma

Cancer charities and the NHS are preparing to investigate whether a cannabis-based mouth spray can treat brain tumours and help patients to live longer.

Doctors will give patients across the UK with a recurrent brain tumour called a glioblastoma the drug, which is known as Sativex, alongside a chemotherapy medication - temozolomide - in a clinical trial in an attempt to kill off cancerous cells.
