>Why even stop smoking if it does not stop 100% of all cases of cancer?

If the intend to ban smoking in a population was to reduce the incidence of lung cancer, and the incidence does not drop after smoking ban, then ban was useless.

On the other hand if it does drop, and the death toll drops by a lot (like in Israel) ... then you're argument is akin to:

"Why stop hitting people with cars when the people hit don't die in 100% of cases ?"
