What happens to your voice box after you stop smoking?

After you stop smoking, your voice box, or larynx, begins to heal from the damage caused by tobacco smoke. Inflammation and irritation gradually decrease, leading to improved vocal quality and clarity over time. The cilia in your respiratory tract, which help clear mucus and debris, start to recover, further supporting vocal health. Overall, many former smokers notice significant improvements in their voice and respiratory function after quitting.
