The debate over what kills cancer cells has a long history.
There have been studies dating back to 1974 that show that cannabis has anti-tumor effects. There was one such study reported in a Washington Post Newspaper on August 18, 1974 which indicated that one of the components of cannabis, THC, slowed the growth of various cancers including lung, breast and a virus-induced leukemia in laboratory mice, and extended their lives by up to 36 percent.
An article written in The Journal of the National Cancer Institute titled “Antineoplastic Activity of Cannabinoids,” reported that they “Lewis lung adenocarcinoma growth was retarded by the oral administration of tetrahydrocannabinol (THC) and cannabinol (CBD). Mice treated for 20 consecutive days with THC and CBD had reduced primary tumor size.”
In 1998, Dr. Manuel Guzman led a research team at Madrid’s Complutense University and discovered that THC can selectively induce programmed cell death in brain tumor cells, while avoiding healthy surrounding cells. In the March 2002 issue of “Nature Medicine”, Dr. Guzman and his team reported that they had destroyed incurable brain cancer tumors in rats by injecting them with THC.
In 2007, Harvard researchers discovered that compounds in cannabis sharply decreased the growth of lung cancer cells.
There is 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 stated that chemotherapy doesn’t even come close to the nontoxic anticancer effects of cannabis compounds. As recently as 2012, two scientists at California Pacific Medical Center in San Francisco discovered that THC stops metastasis in many forms of aggressive cancer.
These are just a handful of studies illustrating how beneficial cannabis can be in the treatment of cancer.
