Many recent studies have found that Cannabidiol (CBD) acts as a potent inhibitor for various types of cancer, including breast cancer, colon cancer, lung cancer, certain types of brain tumors, leukemia, and others. In November 2007, researchers conducted a number of studies and concluded that Cannabidiol (CBD) is able to control the spread of malignant tumors and even delay metastasis (the process of cancer cells spreading to different parts of the body) by “deactivating” a gene responsible for tumor metastasis. Moreover, in addition to its anti-cancer properties, Cannabidiol (CBD) appears to make certain cancer cells more susceptible to chemotherapy. This, combined with documented effects of Cannabidiol (CBD) in relieving pain and treating nausea and vomiting, implies that CBD is a promising adjunct for use alongside existing chemotherapies.
