Scientists at the Complutense University of Madrid will not be able to research the use of THC against brain tumours in humans due to a lack of funding.
In early 2000, the Spanish team led by Dr Manuel Guzman had demonstrated that THC and a synthetic cannabinoid both induced regression of malignant gliomas when tested on laboratory rats (see CC#25, THC destroys brain cancers).

There is currently no effective treatment for malignant gliomas.

The two cannabinoids completely destroyed the tumours in half the rats tested, and prolonged the lives of the rest.

Despite seven months of effort, Guzman has been unable to secure funding for further research in humans.
