I’ve recently come across this study which I thought might be of interest to you guys. It compares the risks for nasal cancer from snuff with other causes. The conclusion seems to be that snuff use in combination with smoking increases the occurrence of malignancies however exclusive snuff users are at fairly low risk. What do you make of it?
