In recent years, cannabinoids have been extensively studied for their potential anticancer effects and symptom management in cancer patients with encouraging results (The Use of Medical Marijuana in Cancer. Birdsall SM, Birdsall TC, Tims LA Curr Oncol Rep. 2016 Jul; 18(7):40.). In one study, scientists found that CBD induced cell death in human breast cancer cells, and in another it was found to have inhibited the spread of aggressive breast cancer.
Another study found that a combination of CBD and THC administered orally relieved cancer sufferers undergoing chemotherapy of nausea and vomiting more effectively than standard treatment. It was also found that the CBD and THC combination was also a more effective pain reliever than standard pain-relieving pharmaceuticals, such as morphine.
It is believed that even though CBD has displayed an ability to reduce symptoms related to cancer, it may also have cancer-fighting properties by targeting the ECS (endocannabinoid system) and affect many essential cellular processes and signalling pathways which are crucial for tumour development (Endocannabinoids and Cancer.Velasco G, Sánchez C, Guzmán M, Handb Exp Pharmacol. 2015; 231():449-72.)
Studies have found that CBD is a potent inhibitor of cancer cell growth in prostate cancer (Sharma M, Hudson J, Adomat H, Guns E, Cox M. In vitro anticancer activity of plant-derived cannabidiol on prostate cancer cell lines. Pharmacol Pharm. 2014;5(8):806–20. https://doi.org/10.4236/pp.2014.58091.), with less effect on non-cancerous cells.
In conclusion, it has been found that CBD has a promising therapeutic potential for treating a variety of diseases, including cancer.
