The precise recipe for this filler depends upon the model. Some cigarettes are dense and contain much more tar while some use porous paper that can dilute the nicotine and tar.
The smoke kills by a mix of thermal damage, poisoning and pulmonary irritation due to carbon monoxide, hydrogen cyanide and other combustion items.
