Been a snuff dipper for close to 50 years as are most of the males I grew up with and I’ve yet to have a single person I know come down with any form of cancer elated to snuff.
25 years of Chaw and dip, finally quit, very hard to do but it was getting too expensive and I developed some polyps in my mouth which gave me a scare but even after 20 years of no tobacco I still get a craving at times.
My husband chewed for 50 years and never had a problem. His grandfather chewed for less time than that and died of cancer of the jaw.
