Affect, Motives for Cannabis Use, Duration of Intoxication, and Cannabis Consequences: Cannabis Use Problem Severity as a Potential Moderator.
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
objectiveThe multistage model of substance use proposes that reinforcement mechanisms and motives for use change as individuals develop substance use disorders, with positive reinforcement driving substance use when substance use disorder symptoms are absent/mild and negative reinforcement becoming dominant when substance use disorder symptoms are more severe. We aimed to determine whether event-level associations between affect, cannabis use, motives for use, and heaviness of use were moderated by cannabis use problem severity, consistent with the multistage model of substance use.
methodWe used ecological momentary assessment data (two observations per day for 14 days) from 571 young adult females who regularly used cannabis. The sample included a majority of sexual minority women and gender diverse individuals (77.6%).
resultsElevated anxious affect was concurrently associated with coping motives for cannabis use and longer duration of intoxication at the event level, but only among those with more severe cannabis use problems. Further, positive affect was concurrently associated with a higher likelihood of endorsing enhancement motives for the full sample, but this association was stronger for those with fewer cannabis use problems. However, many other associations between affect and cannabis use outcomes were not moderated by the severity of cannabis use problems.
conclusionsSome findings were consistent with expectations based on the multistage model. However, results also suggest that positive reinforcement may continue to drive cannabis use among those with more severe cannabis use problems, which is not consistent with what would be expected based on the multistage model.
