The authors wish to add the following amendments and corrections on their paper published in IJERPH [1].

- Page 2399, Figure 3. Death rates for never smokers were computed using death rates for current and former smokers specific for each class of cigarettes smoked per day (1–9 cig./day, 10–19 cig./day, ≥20 cig./day). As a consequence, death rates for never smokers resulted cig./day-specific and not uniquely defined. To solve this problem we computed death rates for never smokers using overall prevalences and RR for current and former smokers (not cig./day-specific). Death rates for never smokers were however not used to compute the life gains. Due to this, replace:
