Researchers at Harvard tested the chemical THC in both lab and mouse studies. They say this is the first set of experiments to show that the compound, THC actually activates naturally produced receptors to fight off lung cancer. The researchers suggest that THC or other designer agents that activate these receptors might be used in a targeted fashion to treat lung cancer.
Although a medical substitute of THC, known as Marinol, has been used as an appetite stimulant for cancer patients and other similar treatments, few studies have shown that THC might have anti-tumor activity.
*HERE IS THE INTERESTING PART* The only clinical trial testing THC as a treatment against cancer growth was a recently completed British pilot study. For three weeks, researchers injected standard doses of THC into mice that had been implanted with human lung cancer cells, and found that tumors were reduced in size and weight by about 50 percent in treated animals compared to a control group. There was also about a 60 percent reduction in cancer lesions on the lungs in these mice as well as a significant reduction in protein markers associated with cancer progression.
