Characteristics of Substance Users
Our study gathered important information about characteristics of pwCF who use substances that have not been previously reported. Substance use was higher across all substances among pwCF who were college-educated, aged 26 to 39 years old, or Black. While male pwCF were more likely to be current users of CBD, e-cigarettes, and cigarettes, pwCF who are female or have other gender identities were more likely to use marijuana currently. Interestingly, current use of e-cigarettes and cigarettes were less likely to have severe or normal lung function compared to non-users; Current use of e-cigarettes and cigarettes was the higher in those with mild or moderate lung disease. There was no significant difference in pulmonary function by usage of marijuana and CBD. Our hypothesis to explain these findings is that individuals with poorer lung function may have increased healthcare interactions therefore a heightened understanding of vaping risks, while those with better lung function may exhibit higher health awareness. It is important to note that while our study identified important demographic and health characteristics associated with various substance use in pwCF, the prevalence of substance use overall was high in our study. Our findings confirmed the importance of incorporating substance use discussions and education into routine care regardless of demographic, health, or socioeconomic status.
