Background and objectives: Screening, brief intervention, and referral to treatment (SBIRT) can reduce substance use, but receipt of these services by those who use cannabis frequently and have cannabis use disorder (CUD) remains unexplored. We examined cannabis use frequency and CUD's associations with the odds of receiving a substance use screening and a healthcare professional discussion among those who used healthcare services.
Methods: Data came from the 2015-2019 National Survey on Drug Use and Health (N = 214,505 aged 18+). Among adults who used cannabis and attended healthcare settings in the past year (N = 36,374), multivariable logistic regression analysis was used to examine associations of cannabis use frequency and CUD with receiving a substance use screen and substance use discussion by a healthcare professional.
Results: Cannabis use frequency was associated with higher odds of receiving a screen (adjusted odds ratio [AOR] = 1.27, 95% confidence interval [CI] = 1.14-1.41 for 300+ days of use) and a discussion among those screened (AOR = 1.83, 95% CI = 1.60-2.09 for 300+ days of use). CUD was not associated with receiving a screen, but it was positively associated with receiving a discussion among those screened (AOR = 1.22, 95% CI = 1.08-1.39). Nonmedical users were less likely to have a discussion among those screened and not screened.
Discussion and conclusions: Findings indicate disparities in screening and discussion of substance use with patients, especially between medical and nonmedical users.
Scientific significance: Study findings provide novel insight into differences in the reach of SBIRT services among adult cannabis users.
