Cannabis chemical stop prostate cancer growth

18 August 2009

Active chemicals in cannabis have been shown to halt prostate cancer cell growth according to research published in the British Journal of Cancer, August 19.

Researchers from the University of Alcala, in Madrid, Spain, tested the effects of the active chemicals in cannabis called cannabinoids on three human prostate cancer cell lines - called PC-3, DU-a45 and LNCaP.

The prostate cancer cells carry molecular 'garages' -  called receptors - in which cannabinoids can 'park'. The scientists showed for the first time that if cannabinoids 'park' on a receptor called CB2, the cancer cells stop multiplying.
