Cannabis Extracts Enhance Anti-Tumor Radiation Effects

Medical Research: What is the background for this study? What are the main findings?
Dr. Liu: It has been known for some time that certain chemicals called cannabinoids that are isolated from the cannabis plant possess anticancer action through the ability to enhance/engage apoptosis and autophagy. These effects are both dependent and independent upon the cognate receptors. These are found at relatively high levels in brain cells. Brain tumors tend to express these at high levels and so we felt these would be good candidates.
The main findings of the current study is the ability that combining the cannabinoids THC and CBD with irradiation can cause a reduction in tumor that is greater than the sum of the individual treatments. That is, when using doses of irradiation or cannabinoids individually, the effects were minimal; however, if they were used simultaneously, the effect was synergistic, and tumor growth was significantly impeded.
