CBD may help prevent cancer from spreading, researchers at California Pacific Medical Center in San Francisco reported in 2007. Cannabidiol stops cancer by turning off a gene called Id-1, the study, published in the journal Molecular Cancer Therapeutics, found. Cancer cells make more copies of this gene than non-cancerous cells, and it helps them spread through the body. - Business Insider - Olivia Mannix and Jennifer DeFalco pictured
