Looking at the World Health Organization document on smokeless tobacco, it appeared they pulled much of their history from a journal article titled:  “Smokeless Tobacco:  The Folklore and Social History of Snuffing, Sneezing, Dipping, and Chewing.”

I looked around a bit, and found a PDF of that article.  You can read it or download it here:
