Abstract

<div class="section"> <a class="named-anchor" id="S1"> <!-- named anchor --> </a> <h5 class="section-title" id="d1601844e195">Objective</h5> <p id="P1">Attitudes towards marijuana are changing, the prevalence of DSM-IV cannabis use disorder has increased, and DSM-5 modified the diagnostic criteria for cannabis use disorders. Therefore, updated information is needed on the prevalence, demographic characteristics, psychiatric comorbidity, disability and treatment for DSM-5 cannabis use disorders in the US adult population. </p> </div><div class="section"> <a class="named-anchor" id="S2"> <!-- named anchor --> </a> <h5 class="section-title" id="d1601844e200">Method</h5> <p id="P2">In 2012–2013, a nationally representative sample of 36,309 participants ≥18 years were interviewed in the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III). Psychiatric and substance use disorders were assessed using the Alcohol Use Disorders and Associated Disabilities Interview Schedule-5. </p> </div><div class="section"> <a class="named-anchor" id="S3"> <!-- named anchor --> </a> <h5 class="section-title" id="d1601844e205">Results</h5> <p id="P3">Prevalence of 12-month and lifetime marijuana use disorder was 2.5% and 6.3%. Among those with 12-month and lifetime marijuana use disorder, marijuana use was frequent; mean days used per year was 225.3 (SE=5.69) and 274.2 (SE=3.76). Odds of 12-month and lifetime marijuana use disorder were higher for men, Native Americans, those unmarried, with low incomes, and young adults, (e.g., OR=7.2, 95% CI 5.5–9.5 for 12-month disorder among those 18–24 years compared to those ≥45 years). Marijuana use disorder was associated with other substance disorders, affective, anxiety and personality disorders. Twelve-month marijuana use disorder was associated with disability. As disorder severity increased, virtually all associations became stronger. Only 24.3% with lifetime marijuana use disorder participated in 12-step programs or professional treatment. </p> </div><div class="section"> <a class="named-anchor" id="S4"> <!-- named anchor --> </a> <h5 class="section-title" id="d1601844e210">Conclusions</h5> <p id="P4">DSM-5 marijuana use disorder is prevalent, associated with comorbidity and disability, and often untreated. Findings suggest the need to improve prevention methods, and educate the public, professionals and policy makers about the harms associated with marijuana use disorders and available interventions. </p> </div>
