Assessing the prevalence and risk factors of marijuana use in adults with disabilities

Public support for the legalization of marijuana (cannabis) for medical or recreational use by adults has grown rapidly over the past two decades. Given the growing prevalence and concerns about potential harms, a better understanding is needed of disparities in marijuana use among adults by disability status.

Using 2015-2019 data from the National Survey on Drug Use and Health (NSDUH), we obtained a national sample of 195,130 working-age (18-64 year) adults. Descriptive and multivariable analyses were conducted to assess the prevalence and risk factors associated with marijuana use among adults by disability status and type.

We found the prevalence of marijuana use was higher among adults with disabilities (16.6% vs 10.9%) compared to those without disabilities, and this disparity widened from 2015 to 2019. Furthermore, the odds of marijuana use varied by disability type. Specifically, adults with vision disability only (OR 1.28; 95% CI 1.14-1.44), cognitive disability only (OR 1.24; 95% CI 1.13-1.35), and those with multiple disabilities (OR 1.22; 95% CI 1.11-1.34) had higher odds of marijuana use compared to adults without any disability.

Adults with disabilities have a higher prevalence of marijuana use compared to those without disabilities. Living in a state with legalized medical marijuana also increased the odds of marijuana use. These findings can help to inform policy and public health surveillance of marijuana use in the U.S. Further studies are needed to monitor the rising prevalence of marijuana use and examine how intensity of marijuana use affects health outcomes in adults with and without disabilities.
