Chemicals in cannabis found to stop prostate cancer

Cannabinoids block a receptor, or molecular doorway, on the surface of tumour cells. This stops them from dividing.

Dr Lesley Walker, from Cancer Research UK, said: “This is interesting research which opens a new avenue to explore potential drug targets but it is at a very early stage – it absolutely isn’t the case that men might be able to fight prostate cancer by smoking cannabis.”

Compounds similar to those found in cannabis have been shown to stop prostate cancer cells from multiplying. Two cannabinoid compounds, JWH-015 and MET, stopped prostate tumour growth in human prostate cells in Petri dishes and also in mice with the disease. They halted the cell-division cycle and killed the cancer cells, and had the greatest effect on aggressive prostate cancer cell types, which do not respond to hormone treatments .

"Some 192,000 men in the US alone are diagnosed with prostate cancer each year, and researchers Inés Díaz-Laviada Marturet at the University of Alcalá, Spain, and her colleagues say the results could offer hope to those affected." New Scientist
