Cannabis Use with Cancer
It is common knowledge that cannabis is helpful in controlling the extreme nausea and vomiting that often accompanies cancer chemotherapy. Cannabis is also helpful for cachexia (extreme weight loss) and pain that is often associated with cancer.
The real excitement comes with the growing evidence that cannabis may actually treat cancer by acting as a perfect chemotherapy medication which kills the cancer cells but not the healthy ones. Back in 1974, researchers at the Medical College of Virginia in Richmond inadvertently found the THC slowed the growth of cancer cells in mice with cancer of the lung, breast and a virus-induced leukemia. Their funding ended since the original goal was to determine its harmful effects to the immune system. In 2000 Guzman and his research team in Madrid, Spain demonstrated that injected THC could shrink or destroy brain cell tumors (Glioma) in rats. The 1974 studies were never published and in recent years there has been little coverage in the U.S. about Guzman's work.
