5 days without smoking: what happens

Research on people who quit suggests that by 5 days without smoking, your lungs' cleaning hairs (cilia) are starting to recover, which can bring a cough as mucus clears. Many people notice a mild cough. A common next milestone: circulation and lung function begin to improve at around 2 weeks. Everyone is different.
