Thanks for sharing! That sounds reasonable to me. Global life expectancy at birth was 71 years in 2021, i.e. 1.24 M microlives (= 71*365.25*24/​0.5). In addition:
Smoking one cigarette is associated with a reduction in life expectancy of 0.487 microlives
So smoking 2.56 M cigarettes (= 1.24*10^6/​0.487) would be associated with a decrease in human living time matching the global life expectancy at birth.
