I was under the impression cigars had mellowing additives only.
It depends on the brand. Most of your finer cigars (hand rolled/made) are just straight dried tobacco leaf, everything from the filler to the wrapper. Some cigars have mellowing agents or flavoring/aroma additives. A lot of cheap cigars/cigarillos and "little cigars" (Swisher, Black and Mild, etc.) have some of the same crap as cigarettes.
