In 1974, a long forgotten study was published in the Washington Post that purported to show that THC “slowed the growth of lung cancers, breast cancers and a virus-induced leukemia in laboratory mice, and prolonged their lives by as much as 36%.”
For some reason, the results of that study were slipped away from the public sphere. But in 1998, researchers had another look:
In 1998, a research team at Madrid’s Complutense University Led by Dr. Manuel Guzman discovered that THC can selectively induce programmed cell death in brain tumor cells without negatively impacting surrounding healthy cells. They reported in the March 2002 issue of “Nature Medicine” they had destroyed incurable brain cancer tumors in rats by injecting them with THC. And in 2007 even Harvard Researchers found that compounds in cannabis cut the growth of lung cancer. There is also an organization called The SETH Group that showed compounds in cannabis can stop the growth of human glioblastoma multiforma (GBM) brain cancer cells. The SETH Group says “No chemotherapy can match this nontoxic anti-cancer action.” Even last year in 2012 a pair of scientists at California Pacific Medical Center in San Francisco found THC stops metastasis in many kinds of aggressive cancer.
