What smoking does to your circulation:
This picture shows a hand with normal circulation, with heat all throughout the hands.
This picture shows the hands of a person who has just smoked a cigarette. The blue part is where there is no heat and the red part shows where there is heat. Smoking a cigarette makes the blood from your hands leave, which in turn lowers the temperature of your hands.
