About Pack Years

A pack year is a unit of measurement used to quantify a person’s exposure to tobacco over time. One pack year equals smoking 20 cigarettes (one pack) daily for one year. This metric helps healthcare providers assess the risk of smoking-related diseases like lung cancer, COPD, and heart disease.
