I was in Poland last year when i was getting 4.7 zloty to the pound. UK branded cigarettes worked out at less than £2 a pack and the best price i got was 4.3 zloty in Krakόw for fuel which works out at less than 90p a litre.
Ok i am not saying drive there but the rate now is over 5.3 zloty to the pound making any brand you want well under £2 per pack, that should be cheap enough to kill you quicker.
