The association between smoking and asthma

ABSTRACT

Epidemiological evidence for the association between active cigarette smoking and asthma is not available. In this review, we aimed to summarize previous studies and gave some information on the association between asthma and smoking to researchers. To date, smoking is thought to be associated with asthma exacerbation, but the relationship between smoking and asthma development is still unclear. In the aspect of lung function, smoking results in a faster reduction in asthmatics and parental smoking causes a decrease in neonatal lung function.
