This is very true, but try switching to Swedish snus. Dipping tobacco still has a lot of cancer risk, whereas snus doesn't, really, so you can take your time quitting. It's the difference between roasted and steamed tobacco; it's the combustion products that get you.
Basically, since 2005, the nitrotesimne levels in US Style smokeless tobacco has declined by more than 75% due to changes in manufacturing (largely), and from say, 80mg to 5mg, in the 1975-2016 period.
Tobacco Specific Nitrosamines are widely acknowledged to be the single largest cancer causing agent in oral tobacco. (https://en.wikipedia.org/wiki/Tobacco-specific_nitrosamines)

My dad swore off of drugs and alcohol, and always said he wanted to work until the day he dies. He's instead spent the last 10 years dying of Alzheimer's.
For what it's worth, I'm inclined to follow my dad's approach. Perhaps with a different interpretation of retiring when I die. But there are some games you just can't win.
