Thanks for the response. It's only been about a week since I've been 100% free of tobacco. I started mixing real chew with the fake herbal mixes. Over the course of 4 weeks I went from 25%fake to 100% fake. I'm still chewing, just using the fake herbal chew in it's place. I'm not sure that this ent specializes in oral cancer.. I know that they are trained to deal w/oc, but do some actually specialize in it?
