Marijuana Cuts Lung Cancer Tumor Growth In Half

The active ingredient in marijuana cuts tumor growth in common lung cancer in half and significantly reduces the ability of the cancer to spread. This according to Harvard University researchers at who tested the chemical in both lab and mouse studies, as reported by the American Association for Cancer Research. The compound Delta-tetrahydrocannabinol (THC) inhibits lung cancers that are usually highly aggressive and resistant to chemotherapy. Although the researchers don’t know why THC inhibits tumor growth, they say the substance could be activating molecules that arrest the cell cycle. THC may also interfere with processes that promote cancer growth. –Julia Whitty
