Not just tobacco.
I've been doing a bit of research on pipe tobacco composition. Thanks to the good folks in the Danish Government, there is some good data on the blends produced there. Without exception, all of the tobaccos produced in DK have humectants and sweeteners added. But that is just the start. Peruse the following links for some more eye-opening information:
Composit List of Ingredients Added, Swedish Match 2005
Pipe Tobacco Composition: STG 2010
Pipe Tobacco Composition: Imperial Tobacco 2008
Pipe Tobacco Composition: Mac Baren
