The endocannabinoid system in our bodies regulate our cancer defense — so it makes sense that cannabis works effectively in this area, and the science backs that up.
For those who dispute the fact that cannabis can cure cancer, I would like to refer you to numerous studies (since 1974!) that show that cannabinoids kills cancer cells, shrink tumors, halts the spread of invasive carcinomas, and prevents occurrence. I don't know if you have the energy or the interest to follow up these links, but if you do value truth over hearsay and propaganda, then I would suggest you look at them. First you have to ask yourself: why don't you know about this? (Then you should get really, really angry).
