Quitting smoking is a vital health decision, but does the damage ever truly disappear? In this episode, we dive into groundbreaking research from McGill University that analyzes over 100,000 lung cells to uncover why former smokers remain at a higher risk for disease. We explore the molecular changes that persist long after the last cigarette, the unique biological signatures left behind in the lungs, and what this means for the future of respiratory medicine and treatment.
