Preclinical Cancer Studies
The Efficacy of Cannabinoids and Whole-Plant Extracts
Dozens of preclinical studies carried out at universities and research institutions throughout the world clearly demonstrate the anticancer effects of primary cannabinoids like THC, CBD, and CBG, as well as whole-plant cannabis extracts. Most major types of cancer have proven to be susceptible to cannabinoids.
Cannabinoids act against cancer cells through four major mechanisms. These mechanisms are usually triggered by activation of cannabinoid or other receptors on the surface of cancer cells. The most potent effect is the induction of apoptosis, or programmed cell death. This is the controlled disintegration of cancer cells. Cannabinoids can also inhibit the reproduction of malignant cells, thus slowing their growth. In solid tumors, cannabinoids can block the development of new blood vessels which drive further tumor growth. Finally, the metastatic process by which cancer cells spread to distant organs has also shown to be mitigated by cannabinoids.
All studies listed here are preclinical and only use cell cultures or animals. This preclinical material is just one piece of the comprehensive Supporting Evidence showing how cannabis fights cancer. You can explore studies that may not be listed here by searching various terms on PubMed.
