While I'm certain cannabinoids are very beneficial to cancer patients, I wouldn't go spouting off "it's a cure!" quite yet. All we know is that it helps destroy cancer cells and protect healthy cells, there are many cancer drugs out there that do that too, but they're not cures.

Plus, there's still carcinogens in weed of course. and I don't know the whole story with Bob Marley, but the guy did die of lung cancer.
