Mounting evidence shows ‘cannabinoids’ in marijuana slow cancer growth, inhibit formation of new blood cells that feed a tumor, and help manage pain, fatigue, nausea, and other side effects.
Cristina Sanchez, a young biologist at Complutense University in Madrid, was studying cell metabolism when she noticed something peculiar. She had been screening brain cancer cells because they grow faster than normal cell lines and thus are useful for research purposes. But the cancer cells died each time they were exposed to tetrahydrocannabinol (THC), the principal psychoactive ingredient of marijuana.
Instead of gaining insight into how cells function, Sanchez had stumbled upon the anti-cancer properties of THC. In 1998, she reported in a European biochemistry journal that THC “induces apoptosis [cell death] in C6 glioma cells,” an aggressive form of brain cancer.
Subsequent peer-reviewed studies in several countries would show that THC and other marijuana-derived compounds…
