Study looks at cannabis ingredient's ability to help children's tumours

UK research into cannabidiol (CBD) comes after surge in parents administering it to children without medical advice

British scientists are investigating whether a compound found in cannabis could be used to shrink brain tumours in children.

The study of the effects of cannabidiol (CBD), the non-psychoactive ingredient in marijuana, was prompted by a growing number of parents giving it to children with a brain tumour after buying it online. The lead researcher, Prof Richard Grundy of Nottingham University's children's brain tumour centre, said in the last six months there had been a surge in parents administering it without medical advice in the belief it might help.
