I have just been reading about giving up smoking and found an incredible fact sheet. All the damage we have done over the years is reversable !!! 
Within 20 minutes after quitting, blood pressure and heart rate decrease
Within 12 hours, carbon monoxide levels in the blood decrease to normal
Within 48 hours, nerve endings and sense of smell and taste both start recovering
Within 3 months, circulation and lung function improve
Within 9 months, there are decreases in cough and shortness of breath
Within 1 year, the risk of coronary heart disease is cut in half
Within 5 years, the risk of stroke falls to the same as a non-smoker, and the risks of many cancers (mouth, throat, esophagus, bladder, cervix) decrease significantly
Within 10 years, the risk of dying from lung cancer is cut in half, and the risks of larynx and pancreas cancers decrease.
Within 15 years, the risk of coronary heart disease drops to the level of a non-smoker
P.S. number 3 is why we have reported better sense of taste and smell.
