Proving causation here is very simple. In the case of BMJ’s study it has been proven that modern smokers triple the mortality before 70 and a 2.8 times likelihood of dying within 4 year increments between ages 70 and 90. Thus, if smokers at any given period are more than double as likely of dying, it has been proven that smoking kills most smokers.

APJH’s study similarly shows that the age adjusted annual mortality rates per capita among modern smokers vs. modern non-smokers is such that the etiological fraction (the percent of mortality among smokers that is excess in their respective age groups) is 56.5 percent.
