Kratom Use and Suicidal Thoughts and Behaviors in the United States.
Article in Substance use & addiction journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe rise of suicidal thoughts and behaviors (STBs) in the United States and their association with substance use disorders, including the emerging concern over Kratom-a psychoactive substance-necessitates an investigation into its role in STBs. This study provides the first epidemiologic assessment of the association between Kratom use and STBs in the United States.
methodsThis study leveraged data from the 2021 National Survey on Drug Use and Health (NSDUH) to examine the association between Kratom use and STBs. The NSDUH was carried out among a representative sample of American individuals. Our study sample comprised 47 291 individuals aged 18 and older across the United States. Lifetime Kratom use was the exposure, while outcomes included past-year suicidal thoughts, plans, and attempts.
resultsPersons who use Kratom (PWUK) exhibited higher odds of reporting past-year suicidal thoughts (odds ratio [OR]: 2.14), plans (OR: 1.95), and attempts (OR: 2.50) compared to persons who never used Kratom. The associations also varied by sex and race, with pronounced effects among male and Black individuals. Specifically, subgroup analyses revealed higher odds of suicidal thoughts among Black PWUK (OR: 11.00) and among male PWUK (OR: 2.74).
conclusionsThe findings suggest a significant association between Kratom use and STBs in the U.S. adult population, with variations by sex and race. These results highlight the need for further research examining the causal relationships between Kratom use and STBs, including whether episodic use differs from addiction, as well as assessing the associations of Kratom use with other mental health conditions. This understanding is crucial for informing the development and implementation of targeted interventions, policies, and programs aimed at addressing Kratom use and its mental health consequences.
