Cannabis chemicals may provide a new way of treating deadly brain cancer, new research suggests.
Scientists have shown that cannabinoids - the active ingredients responsible for the drug's "high" - hold back the growth of blood vessels which feed the tumour.
Cutting off tumours' blood supply is one of the latest anti-cancer strategies being explored by scientists.
In the Spanish study cannabinoids significantly reduced the growth of tumours in laboratory mice.
About 4,400 new cases of brain tumour are diagnosed in the UK each year.
Only about 6% of people diagnosed with these high grade cancers live for more than three years.
The disease is normally treated with surgery, followed by radiotherapy alone or in combination with chemotherapy.
But the main tumour often grows back again to kill the patient.
