I'm sorry, is that cigarette kosher?

Check out the article Cigarettes may contain pigs blood. The headline reads: CIGARETTES may contain traces of pig's blood, an Australian academic says with a warning that religious groups could find its undisclosed presence "very offensive". Is that really the ingredient of biggest concern? I get the argument from a religious standpoint, but I'm guessing pig blood is one of the healthiest ingredients in cigarettes (unless someone would like to argue for acetone or tar?).
