 This study examined the association between cannabis use and small airway function in a general population sample. The results showed that cannabis use was associated with increased peripheral airway resistance and reactance among both men and women. However, these associations were stronger and more statistically significant among women. Additionally, the associations were less pronounced or non-existent after bronchodilator use, suggesting that cannabis induced changes in small airways may be at least partially reversible.
