Respiratory diseases

Smoking has been causally linked to numerous diseases, especially those of the respiratory and cardiovascular systems, over the past 50 years1. In the developed world, exposure to tobacco smoke is the main risk factor for chronic obstructive pulmonary disease (COPD)2, a major and increasing global health problem characterized by persistent and progressive airflow limitation associated with an enhanced chronic inflammatory response that may lead to parenchymal tissue destruction and emphysema3.

In susceptible individuals, cigarette smoke (CS) rapidly provokes an array of biological responses, including apoptosis, oxidative stress, and endoplasmic reticulum (ER) stress, which, with sustained exposure, lead to non-resolving inflammation and emphysematous changes4.
