What he did was he got some nicotine free substitute that he chews to get himself off the nicotine. He says because there's no nicotine he chews a lot less, but he's still trying to kick the oral fixation.
I dipped Copenhagen snuff for 8 long years, when I thought I was ready to stop I did. You have to be ready to quit. I never used nicotine gum or the patch either, I just chewed a lot of gum and dipped that beef jerky chew. That was 5 years ago. Good Luck!
