CBD and cannabis have been studied in other specific cancers. A 2013 study published in the journal Chemotherapy studied the effects of synthetic THC against gastric cancer grafts in rodents. Rodents treated with the THC saw a 30 percent reduction in tumor growth over 14 days of treatment when compared to the control. A 2012 Journal of Molecular Medicine study found tumors in mice with laboratory-induced colon cancer shrunk with CBD treatment. A 2013 study published in Molecular Cancer Therapeutics found that CBD triggers cell death in certain lung cancer cell lines, decreasing tumor viability.
For some, having more than trace amounts of Tetrahydrocannabinol (THC) might not be a big deal, but if you’re being drug tested at work, operating heavy machinery, or fall into a number of other categories, you may want to keep the THC to a bare minimum. In order to qualify as a legal hemp product, CBD oil must contain less than 0.03% THC. Look for CBD oil certified to have low levels of, or zero, THC in them. Many reputable sellers do offer products that have absolutely no THC in them at all, so if you are concerned about keeping even trace amounts of TCH out of your body, it is best to look for those products and sellers.
