People entering opioid substance use treatment have low rates of naloxone knowledge and possession.
Article in Drug and alcohol dependence, 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
BACKGROUND AND
aimsDeaths from opioid overdose are increasing in the United States (US) and distribution of the opioid antagonist naloxone is one key strategy to reduce mortality. In this cross-sectional survey, we assess the association of high-risk behaviors with possession of naloxone and knowledge of where to find it. SETTING AND
participants5663 adults entering treatment for opioid use disorder at facilities throughout the US during the calendar year 2022 were surveyed. ANALYSIS: Using a logistic regression analysis, we compared self-reported ownership of naloxone and knowledge of where to find naloxone between individuals with different self-reported types and routes of opioid use, as well as those with a history of opioid overdose compared to those without.
findingsPatients reporting fentanyl, heroin, and more than one type of opioid use had higher rates of naloxone possession than those reporting oxycodone use alone. Patients that reported injection drug use were more likely to possess (61 %) and know where to get (77 %) naloxone than those who did not inject drugs (44 % possessed and 58 % knew where to find naloxone, p < 0.001 for each comparison). Patients with a self-reported history of overdose were more likely to possess (59 %) and know where to get (77 %) naloxone than those without a history of overdose (42 % and 55 % respectively, p < 0.001 for each comparison).
conclusionsGaps in naloxone possession and knowledge persist amongst patients entering treatment for opioid use disorder. Additional efforts to expand naloxone ownership are critical, including comprehensive educational programs, involvement of community-based organizations, and bystander training.
