Chest pain: You have a fairly short history of tobacco exposure. We measure exposure by asking how many packs per day you smoke times the number of years you have smoked that much. So if you smoked about 1.5 packs/day times 4 years you have a 6 pack year history of smoking. It is usually past 20 pack yrs that you start showing serious consequences. STOP SMOKING and STAY OFF!!!
