In any unstable situation (war, sanctions, blockade, siege, whatever), cigarettes quickly turn into a currency. They're light as a feather, they don't spoil, and there's an ever-increasing demand for them. Two packs will get you more than a gold necklace in any such situation, worldwide.
I understand cigarettes in the context. They just wanted Marlboros more than other brands. Some of the others in the group has Camels and some other famous British brand, but they were not as popular as American Marlboros.
