OK.
1 carton equals 200 cigarettes.
200 x 7= 1400 minutes
1400 ÷ 60 = 23.3333333 hours
So each carton is equal to removing about a full day of life as the saying goes.
I'm not sure of the reasoning for this post. Whether its even pro or anti smoking.
With the way 2020 is going, is this a warning or a feature?
