Just a recent odd thing that happened on the way home.

I was on a flight overseas and if you follow the signs they allow 2 "carton" of cigarettes per person (or family?)

The person a row up and over from me had two cartons with 1000 cigs each. He was chatting about how this will last him 2 months.

Looking around the net that's 5 to 10 minutes each. Doing the math that's 33 a day and from 3 to 5.5 hours of smoking a day.
