Retrospective Event-Level Patterns of Cannabis-Impaired Driving.
Article in Journal of studies on alcohol and drugs, 2026. 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
objectiveCannabis-impaired driving (CID) is an increasing public health concern, particularly among emerging adults. Despite growing prevalence, little is known about episode-level patterns of use and impairment before driving. This study examined detailed features of recent and heaviest CID episodes to better understand high-risk driving contexts.
methodParticipants were 149 emerging adult cannabis users (ages 18-29) reporting ≥3 instances of driving after cannabis use in the past 3 months. Event-level data were collected via retrospective self-report of the most recent and heaviest CID occasions. Participants reported method of use, amount consumed, wait time before driving, subjective intoxication, driving distance, alcohol co-use, and the presence of passengers. Paired-sample
resultsMore than 60% reported actively using cannabis while driving, and more than one third reported driving after simultaneous cannabis and alcohol use. Passengers were present in 46% of the most recent driving episodes and 35% of the heaviest driving episodes. Subjective intoxication ratings were significantly higher during the heaviest episodes (
conclusionsFindings highlight high-risk contexts in CID, including simultaneous substance use and driving while intoxicated, often with passengers present. Retrospective event-level analysis offers a nuanced understanding of CID behaviors and underscores the need for prevention strategies that address situational risk factors.
