Marijuana kills cancer cells

"The study by Manuel Guzmán of Madrid Spain found that cannabinoids, the active components of marijuana, inhibit tumor growth in laboratory animals. They do so by modulating key cell-signalling pathways, thereby inducing direct growth arrest and death of tumor cells, as well as by inhibiting the growth of blood vessels that supply the tumor.

The Guzman study is very important according to Dr. Ethan Russo , a neurologist and world authority on medical cannabis: "Cancer occurs because cells become immortalized; they fail to heed normal signals to turn off growth. A normal function of remodelling in the body requires that cells die on cue. This is called apoptosis, or programmed cell death. That process fails to work in tumors. THC promotes its reappearance so that gliomas, leukemias, melanomas and other cell types will in fact heed the signals, stop dividing, and die."

  • my dad was a HUGE pothead... Lifer... and he currently has several tumors of the brain.. until he quit smoking, the tumors never MAJORLY affected him. (he had mild headaches) when he quit smoking, within a month he had lost vision in his left eye, and had to have brain surgery to remove the most prominent of the tumors. he regained his vision, and recently lost it again. the tumors have continued to grow...
    no one knows for sure, and it's just a speculation, but could the marijuana really slow the growth of cancer of the brain??
    quit debating. Figure it out, damnit!

  • The article goes on to say how this information has been supressed because it challenges the prohibition of marijuana. Do you think marijuana use can really inhibit tumor growth?

    What are your thoughts?

  • I think that they need to look further into this and see if it helps with cancer. Why not? What would it hurt? The cure just might be as simple as that.

  • Ummm what kind of cancer cells were they? There are hundreds of different cancers so maybe if you are a mouse and you smoke marijuana and have just the right cancer you can be cured. Great

  • There's TONS of different kinds of cancer cells and just b/c it works in rats does not mean it will work in humans. If this 'study" was totally true then no one who smokes weed would get you really believe that? It's also been shown that chemo kills cancer cells but guess what? It doesn't work all the time! It's also been shown that scorpion poison kills cancer cells. They have not found the cure for cancer and when and if they do I can guarantee it wont' be from weed
