Quitting smoking produces a measurable, dose-dependent reduction in death rate

Evidence

A comprehensive study of nearly a million people who were followed over 10 years revealed that smoking is even more harmful than previously was known (Carter et al., 2015). The study found more diseases linked to smoking. Several aspects of the new findings verify these linkages. The heavier the smoking, the higher the death rate. Among former smokers, the longer the period since quitting, the lower their death rate. — Albert Bandura, Moral Disengagement, 1630
