Cannabis Vaping Among US Adults With Disabilities: Findings From the 2022 Behavioral Risk Factor Surveillance System.

Objectives: Studies have demonstrated that people with disabilities are more likely to use cannabis than people without disabilities. However, less is known about novel forms of use, such as cannabis vaping, in this population. We examined the correlates of cannabis vaping among people with disabilities and the association between cannabis vaping and the frequency of cannabis use in any form.

Methods: We used data from the 2022 Behavioral Risk Factor Surveillance System to examine the association between disabilities and past-month cannabis vaping, as well as the number of days that cannabis was used in the past month, among US adults. We used weighted multivariable logistic and modified Poisson regression models with incidence rate ratios to examine the associations.

Results: The prevalence of cannabis vaping was higher among adults with any disability (4.6%) than among adults without disabilities (2.8%); adults with only cognitive disabilities had the highest prevalence (8.2%). Daily nicotine vaping (adjusted odds ratio [AOR] = 6.04; 95% CI, 4.14-8.80), former cigarette smoking status (AOR = 1.67; 95% CI, 1.25-2.25), and being aged 18-24 years (vs ≥65 y) (AOR = 11.07; 95% CI, 7.05-17.38) were associated with higher odds of cannabis vaping among adults with any disability. Disability status modified the relationship between cigarette smoking and cannabis vaping (P < .001). Additionally, among adults with disabilities, the rate of cannabis-use days was higher among adults who vaped cannabis (adjusted incidence rate ratio = 1.28; 95% CI, 1.19-1.36) than among adults who did not vape cannabis.

Conclusions: Among adults with disabilities, nicotine consumption by vaping was associated with cannabis vaping. Our findings highlight the need for interventions that reduce the risk of polysubstance use (ie, nicotine and cannabis) in this population.
