Abstract summary 

Kratom leaf products are increasingly consumed in the United States, with many consumers reporting they experience beneficial effects from kratom use. However, there is a growing concern for kratom's potential to result in dependence when used regularly. As such, we sought to assess, using Diagnostic and Statistical Manual of Mental Disorders, (DSM-5), diagnostic criteria for substance use disorder, the prevalence of "kratom use disorder" (KUD) among kratom consumers.Our cross-sectional study used an online, anonymous survey between February and May 2023. Through nonprobability sampling, we recruited people older than 18 years who currently consume kratom. Participants were asked about their kratom consumption patterns, adverse effects perceived to stem from kratom consumption, comorbid diagnoses, and components for a DSM-5, substance use disorder, adapted for kratom.Among the total sample (N = 2061), KUD criteria were met by 25.5% of participants (n = 525); the most commonly reported symptoms were tolerance (n = 427, 81.3%) and withdrawal (n = 357, 68.0%). After adjusting for age, gender, daily frequency of kratom consumption, and history of either a substance use disorder or a mental health condition, those with a concurrent diagnosis of another substance use disorder had 2.83 times higher odds of meeting KUD criteria (95% CI, 2.19-3.67) compared with those without one.In this large cross-sectional study, most participants who met the criteria for a KUD diagnosis were categorized as having a mild or moderate KUD. Individual characteristics associated with KUD were related to being male, young, consuming kratom frequently, and having psychiatric and substance use disorder comorbidities.
