Smoking is a risk factor for pulmonary fibrosis (PF). If you’re diagnosed with PF, you should stop smoking.
How smoking causes pulmonary fibrosis
Studies suggest that if you’ve ever smoked, you’re more likely to develop pulmonary fibrosis than people who have been non-smokers all their lives.
Tobacco smoke contains around 5,000 chemicals, including tar and nicotine. However, researchers don’t yet understand which chemicals in tobacco smoke are responsible for putting smokers at increased risk of developing pulmonary fibrosis.
