Oral use - What's in Chewing & Dipping Tobacco?

[mouthwater]

Many have heard rumours that abrasives are included in dipping tobacco to increase nicotine absorption (discussed previously). Throughout my original research, I've only recently (as of twenty minutes ago) learned of a single dipping/chewing tobacco distributor that releases full product ingredient lists for all it's brands (including nasal snuff and snus). I've compiled information on the most-notable chewing/dipping/plug tobacco brands available in the US from this distributor in a more reader-friendly manner.
