«Dozens of major studies have been published in the last few years that indicate that the chemicals in cannabis in the lab and in animals have a significant effect on fighting almost all major cancers, including brain, breast, prostate, lung, thyroid, colon, skin, pituitary, melanoma and leukemia cancers. They do this by promoting the death of cancer cells that have forgotten how to die, as well as a reduction in their crucial blood supply, while leaving healthy cells untouched.

But why, you may wonder, would cannabis have any effect on cancer? The answer can be explained in one word – endocannabinoids. Amazing as it sounds we’re all born with a form of cannabis already in our bodies. It’s called the Endocannabinoid System. The Endocannabinoid System, or ECS, influences multiple physiological processes. This intricate system modulates energy intake as well as nutrient transport, metabolism and storage.

A completely natural collection of compounds, endocannabinoids are our body’s own form of marijuana and are involved in most of our cells and structures. They control a variety of functions in the nervous system, heart, reproductive and immune systems. Endocannabinoid messengers help the cells communicate. Typically they protect our good cells while killing the bad ones like cancer cells.»

«There are multiple mechanisms of action identified, by which cannabis kills cancer cells, and they are divided into various categories. Among these are:

  • Antiproliferative effects (Prevents cancer cells from reproducing) Normally, that’s one of the hallmarks of the cancer cell —that it keeps reproducing… So, if you stop the reproduction, that’s an antiproliferative effect.
  • Antiangiogenesis effects (Prevents formation of new blood vessels needed by tumor to grow) —This means that the cannabinoids will stop the tumor from being able to elaborate, or grow, new blood vessels to support the growth of the tumor.
  • Antimetastatic effects (Prevents cancer from spreading to other organs) —That is simple enough to mean that the cannabinoids block the ability of the cancer cells to spread into other tissues. —And there’s another effect that has a wild name…
  • Apoptotic effect (Induces cell to seek its own death) —Apoptosis refers to the ability of cannabinoids to speed the death of the abnormal cells.»

«Hemos observado que los cannabinoides tienen un efecto inductor de la muerte de las células tumorales, un efecto inhibidor de lo que es el crecimiento —la multiplicación— de las células tumorales… Lo que hacen es disminuir el crecimiento de los tumores.»
