Cannabis has been shown to possess anti-tumor properties since 1974. The study from this study was reported in Washington Post in August 18, 1974, showing that “ THC, a cannabis`s compound 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 percent.”
A year later, a 1975 study published in the Journal of the National Cancer Institute entitled “Antineoplastic Activity of Cannabinoids,” reported that “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.”
According to a 1998 research done by scientists at Madrid’s Complutense University Led by Dr. Manuel Guzman, THC induces programmed cell death in brain cells selectively, meaning that it kills off affects cells and leaves the healthy ones intact. The team of researchers reported in the March 2002 issue of “Nature Medicine” that injecting rats with THC had destroyed their brain cancer cells. Moreover, in 2007 Harvard researchers discovered that the compounds found in cannabis inhibit the growth of lung cancer. The organization called the SETH Group showed that cannabis`s compounds can even inhibit the growth of glioblastoma multiform (GBM) brain cancer cells. “No chemotherapy can match this non-toxic anti-cancer action,”– the group stated. Ultimately, a 2012 study done by the scientist at California Pacific Medical Center in San Francisco found THC stops metastasis in many types of aggressive cancer.
