Persistent smoking significantly increases the risk of premature death from all causes and coronary heart disease, while quitting smoking mitigates this risk to levels comparable to non-smokers.

Qing Qiao (2000) reported a cohort. Smoking vs. Non-smokers was evaluated on 35-year all-cause mortality (HR 1.62, 95% CI 1.40-1.88). Current smoking increased the risk of 35-year all-cause mortality compared with non-smokers (HR 1.62; 95% CI 1.40-1.88) among middle-aged Finnish men.
