A compound in cannabis is 'significantly' effective in destroying cancerous tumours in leukaemia

A compound in cannabis is 'significantly' effective in destroying cancerous tumours in leukaemia, research suggests.

A new study found that combining existing chemotherapy treatments with cannabinoids – the active chemicals in cannabis – had better results than chemotherapy alone.   The findings suggest that a lower dose of chemotherapy can be used on patients, minimising side effects of the treatment, say researchers.

Furthermore, scientists discovered that order the treatment was administered was crucial - using cannabinoids after chemotherapy resulted in a greater death of the blood cancer cells.

Lead author of the study, Dr Wai Liu, from St George's, University of London, said: 'We have shown for the first time that the order in which cannabinoids and chemotherapy are used is crucial in determining the overall effectiveness of this treatment.'
