In 2007, researchers at Harvard University discovered that THC, one of the most active ingredients in medical marijuana, cuts tumor growth in common lung cancer in half and significantly reduces the ability of the cancer to spread.
This study characterized the effect of THC on EGF-induced growth and metastasis of human non small lung cancer cell (NSCLC) – a type of lung cancer that is usually highly aggressive and resistant to chemotherapy. The researchers implanted human lung cancer cells into mice, and then injectd them with standard doses of THC. After just three weeks, the mice showed a 50% reduction in tumor weight and size compared to a control group. The mice also showed a 60% decrease in cancer lesions on the lungs and a significant reduction in protein markers associated with cancer progression.
