Tobacco Use Pack Years Decimal
Notes: A quantification of smoking exposure, calculated as the number of cigarette packs smoked daily multiplied by the years smoked (e.g., 1 pack per day X 20 years = 20 pack years).<br/>The number of pack years is the unit that describes the total exposure to tobacco smoke, which is the number of smoked packs of cigarettes per day (one pack = 20 cigarettes) times the number of years of smoking. A different formula is often used for rolling tobacco and pipes, with one of the parameters being the number of grams per week.<br/>
