The National Cancer Institute has released several studies which demonstrate the anti-tumor effects of CBD or cannabidiol, a non-psychoactive chemical compound found in cannabis.
A study conducted on both mice and rats suggests that CBD “may have a protective effect against the development of certain types of tumors," by inducing tumor cell death, inhibiting cancer cell growth and/or by controlling and inhibiting the spread of cancer cells.
A study conducted by the California Pacific Medical Center suggests that CBD “turns off” the gene involved in the spread of breast cancer. These scientists noted that CBD inhibits ID-1, an action that prevents cancer cells from traveling long distances to distant tissues. Find the comprehensive abstract for this study here
