It's actually a 100% death rate as all smokers sure. Jokes aside, your statement doesn't have meaning. Many deaths are not attributable to a single cause. However, it's been studies endlessly and is well accepted that smoking increases all-cause mortality.

Im not arguing against that at all. I was making a point about the magnitude of that impact.

People tend to over-estimate the impact of both smoking and obesity.
