What do smokers do to remove the build up of mucas from the lungs?

Smokers often try to clear mucus from their lungs by coughing, which helps expel the accumulated phlegm. Some may also use over-the-counter expectorants to thin the mucus, making it easier to cough up. Additionally, practices such as steam inhalation, staying hydrated, and engaging in physical activity can aid in mucus clearance. However, the most effective long-term solution is to quit smoking, as this reduces mucus production and improves lung health.
