Pack-years

Definition

Pack-years quantify smoking exposure, calculated by multiplying the number of packs of cigarettes smoked per day by the number of years the person has smoked. It is a critical measure in assessing cumulative tobacco exposure and its impact on health, especially pulmonary wellness.

4. Assessing pack-years helps healthcare providers tailor nutritional and therapeutic interventions for patients with respiratory conditions.
5. Nutritional strategies may be employed to mitigate some adverse effects seen in individuals with high pack-year histories.
