I have been chewing for a long time. I had a cow elk a couple of years ago with her face in mine. She never ran from me. When deer hunting I have never noticed a big difference either. I was kinda wondering about the new green apple skoal that is out. Seems to me like it might work as a cover-up. After a week in the mountains I think that I would be focusing more on my armpits than on my copenhagen.
