Edible cannabis use on simulated driving performance.
Article in Traffic injury prevention, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo assess driving performance after consuming edible cannabis using a driving simulator, examining frequency of use, THC dose, and rural versus urban settings.
methodsAdults in Denver, Colorado (
resultsDaily-use group drove slower than the occasional-use group (decrease in average speed from pretest of 2.49 mph (urban,
conclusionOur study found significant changes in driving performance following edible cannabis use, including findings related to effect duration, use frequency, and road settings. The occasional-use group showed greater impairment than daily-use group, suggesting tolerance contributes to outcomes beyond THC concentration alone.
