Frequently Asked Questions
A pack year is a measure of cumulative smoking exposure, defined as smoking 20 cigarettes (one pack) per day for one year.
Pack years = (packs smoked per day) × (years smoked). If you smoke 20 cigarettes per day, that equals 1 pack per day.
Pack years help assess the risk of lung cancer, COPD, and other smoking-related diseases. Higher pack years indicate greater exposure and risk.
