BackgroundReports of kratom (Mitragyna speciosa) use, a medicinal plant widely found in Southeast Asia, are on the rise in the US. However, the prevalence and characteristics of individuals who use kratom in the US is unknown.ObjectiveTo estimate lifetime prevalence of, and descriptive characteristics associated with, kratom use in a sample of the US general population.MethodsA cross-sectional survey was administered online by Qualtrics® research panel aggregator. Utilizing quota-based sampling, data was collected from a US sample aged 18-59 years, representative to age, geographic region, ethnicity, income, and education level. Data was collected regarding respondent demographic/clinical characteristics, as well as frequency/patterns of kratom and other drug use.ResultsAmong 1,842 respondents, 112 (6.1%) reported use of kratom within their lifetime. Respondents who used kratom were largely between 25-44 years old, male, employed, and at higher educational levels. A total of 24.1% to 47.3% of respondents indicated self-reported diagnoses for addiction, and 42.9% reported having previously received treatment for addiction. A total of 71.4% to 92% of respondents who used kratom also reported use of other drugs, including nicotine, cannabis, cocaine, ecstasy, methamphetamine, and heroin.ConclusionsTo our knowledge, this analysis provides the first estimate of kratom use in the general US population, providing insight on demographic/clinical characteristics of individuals reporting use.
