Cigarettes are much better when it comes to traveling, though, because if something happens and you have to evacuate it's pretty easy to grab a backpack or duffel bag filled with cartons of smokes.  Also, if you're in the US (or near a US military base overseas) it might be wise to strike up a friendship with someone in the US military, especially if that someone doesn't smoke.  Because they might go shopping for you on base and bring you back a few cartons . . . at a much better price than what you can get yourself.  I don't smoke, but I certainly didn't mind going shopping for a friend every now and then back when I was in the military.

And come to think of it, the liquor is probably still be cheaper on base too.
