I would think that the deer would actually be attracted to it, much like molasses. Chewing tobacco like Skoal or Cope, has TONS of sugar in it. And when you spit, its mostly the disolving sugar that carries the tobacco juices, which are small. I might start doing it this year in the stand, ive done it off and on anyways for about 4-5 years now, but not usually while hunting.
