I chew. A LOT, about 4 cans a week. Here's my question. For all you guys out there who do it, does it make a difference? (I know this is a lot similar to the smoking thread) I'm curious though. I know it makes my breath smell like cherry or mint, whatever i've got in.I don't do it in the stand and haven't ever. I just want to know if it will make a difference in the negative way. Any experiences?
