Smoking, smoking cessation and heart disease risk: A 16-year follow-up study

This study measures the association between daily smoking and the risk of heart disease. The number of years of cessation required for former daily smokers to achieve a risk level similar to that of people who have never smoked daily is quantified. The study is based on data collected from 1994/1995 through 2010/2011 by the National Population Health Survey.
