Potential risk factors for methamphetamine use among inmates in a Japanese prison.
Article in BMC psychiatry, 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
backgroundIn Japan, drug addiction recovery guidance and social reintegration programs are implemented for eligible inmates in many prisons. However, methamphetamine addiction, especially among those with a history of thinner inhalation, often seems not to be adequately addressed in addiction treatment programs. The comorbidities of substance use disorders may be generally overlooked. This study aimed to provide valuable data for guiding the development of programs to combat drug addiction and support social reintegration for inmates. The first step of this study sought to determine the association between history of daily/regular methamphetamine use and use of other substances as well as the relationship between methamphetamine use and sociodemographic background.
methodsThis retrospective study included 470 consecutive inmates whose data were obtained and who consulted a certified psychiatrist. Chi-square tests and paired t-tests were used for the analysis. Furthermore, a multinominal regression analysis was performed.
resultsOur findings revealed that the history of daily/regular methamphetamine use was significantly associated with the history of psychiatric consultation, sexually transmitted infections, daily/regular thinner inhalation, and daily/regularly tobacco smoking. Moreover, daily/regular thinner inhalation was initiated at a significantly younger age than methamphetamine use. In addition, tobacco smoking was initiated at a significantly younger age than methamphetamine use.
conclusionThe present study suggested that a history of daily/regular thinner inhalation and daily/regular tobacco smoking may serve as potential risk factors for the development of daily/regular methamphetamine use. Furthermore, these findings highlight the significant association between thinner or nicotine addiction and subsequent methamphetamine addiction. These results may provide valuable insights for supporting and protecting inmates with methamphetamine addiction as well as individuals at risk.
