What goes into a cigarette and why?

Tobacco companies choose all of the ingredients in cigarettes for a reason; most of them help foster nicotine addiction or otherwise allow the smoker to get harsh smoke down into their lungs.

A few times an hour, a "chef" will demonstrate the ingredients used in the manufacture of cigarettes in an engaging show. In between presentations, people may take a closer look at the ingredients -- detailing the chemical reasons why they're included in the whole package.
