It's good. I used a mint "snuff" of a different type to wean myself off snus (sort of a three step process). It wasn't that kind but same idea.
Very similar to you, I used Copenhagen's Winter Green for a week and a half to quit smoking. I believe it kept the nicotine in my system yet broke my hands of the habit of lighting up. I was on a rig at the time and threw my tin out the window a mile from home, being a randy youngish buck at the time I knew SWMBO would not be receptive to a lip full...if you catch my drift
