Cannabis Kills Cancer Cells in Preclinical Studies

On 16 July 2015, the National Cancer Institute (NCI) updated the FAQ on their web site, Cancer.gov, which now includes multiple facts about cannabis and its effect upon cancer cells.

Not only has cannabis been used for medicinal purposes for thousands of years, but a small part of the government finally seems to agree in the benefits for patients when presented with cannabis for medical use:

Chemical components of Cannabis, called cannabinoids, activate specific receptors throughout the body to producepharmacologic effects, particularly in the central nervous system and the immune system.

Oddly enough, Snopes.com claims that this same research is inconclusive. Snopes also claims that Cancer.gov only claims to have tested on animals in labs, which is clearly not true.

The potential benefits of medicinal Cannabis for people living with cancer include antiemetic effects, appetite stimulation, pain relief, and improved sleep. Although few relevant surveys of practice patterns exist, it appears that physicians caring for cancer patients in the United States who recommend medicinal Cannabis do so predominantly for symptom management. A growing number of pediatric patients are seeking symptom relief with Cannabis or cannabinoid treatment, although studies are limited. The American Academy of Pediatrics has not endorsed Cannabis and cannabinoid use because of concerns about brain development.

If this is not enough to convince you, here are some extra links showing the effects of Cannabinoids on cancer cells:
