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.
