Currently, there is very little research surrounding CBD. CBD was just legalized in 2018 and the science has not had time to catch up. The limited studies available are hard to interpret and come to a definite conclusion because the industry is still very unregulated. There is no guarantee of consistency which makes is hard for researchers. Having said that, the research that has been done thus far is very positive for the future implications of CBD for cancer, seizures, pain, anxiety, etc. Currently, the FDA does not endorse CBD as a treatment for diagnosis such as anxiety and depression.
Just this year, a study was published about the anti-tumor effects of CBD. The full research article is here – https://www.mdpi.com/2218-273X/9/8/302/htm In discussion, they say “Studies have shown that CBD can inhibit tumor cell proliferation and metastasis or induce autophagy or apoptosis in various cancers such as glioma, leukemia, prostate cancer, and breast cancer. In this study, we found that CBD could arrest SGC-7901 cells at the G0-G1 phase and induce apoptosis of SGC-7901 cells by activating the mitochondrial apoptosis pathway.”
