Was talking about this a few weeks ago with my friends son, who said his college economics prof did a lecture about this very topic. He said one of the things the professor talked about was how much the cig taxes directly effect the economy, and how without them [cig taxes], the nations economy would take a HUGE hit, that would have implications on more things then you could possibly imagine. Potentially catastrophic to the already shaky economy. Basically, there is such an ungodly amount of money raised from those taxes, that they couldn't ban cigarettes even if they wanted to.
