No it does not. Why would you even ask that question? What would make you believe smoking Spice cures Cancer? If anything it probably contributes to the factors which cause Cancer. I’m not a doctor, but I think it’s safe to say smoking Spice will definitely increase your chances of getting Cancer. You shouldn’t do it. Unless you have to. Unless you’re being held hostage and the only way to avoid death is to smoke Spice, I’d say don’t do it.
