It's important to note that former smokers are also at risk. Tobacco smoke damages the lungs at the cellular level—damage that not always can be reversed. Also, COPD's more severe effects may not appear until later in life, accompanying the natural decline in lung function that occurs as we age. Consequently, former smokers may face declining lung function and COPD years or decades after they quit.
