In epidemiology, the study of the distribution and determinants of health-related states, understanding the impact of smoking on public health is crucial. Smoking is a major risk factor for several chronic diseases, including cardiovascular disease, chronic obstructive pulmonary disease (COPD), and various cancers. NRT is significant as it offers a strategy to reduce the prevalence of smoking and, consequently, smoking-related diseases. This reduction can lead to lower morbidity and mortality rates, improving population health outcomes.
