Added cellulose in St. Casura?

Im only asking because I’m familiar with pure cellulose powder, and this snuff feels nearly identical. Light, almost rubbery. Holds its shape when compressed, with the consistency of a dense sponge. So, is this an additive in their snuff?

pure cellulose powder cost about $18 dollars a lb. I think it an anti caking ingredient. You can get whole leaf tobacco for $12 an Lb, Wether he uses it that is the question only he can answer.  

sometimes certain essential oils change the consistency of snuff a bit.
