Sleep quality and duration as predictors of alcohol and cannabis use motives in daily life.
Article in Addictive behaviors, 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
objectiveAlcohol and cannabis are two of the most widely used substances in the United States, where sleep problems are also prominent. Although poor sleep is linked to substance use, little is known about how prior-night sleep contributes to next-day decisions to use substances in daily life. This study tested the impact of prior-night sleep duration and quality on momentary motives for alcohol (Aim 1) and cannabis use (Aim 2).
methodsAdults reporting simultaneous use of alcohol and cannabis at least twice per week (N = 88; 60 % female, 85 % White, Mage = 25.22) completed 14 days of ecological momentary assessment with 5 + surveys per day. Morning surveys assessed prior-night sleep duration and quality, and all surveys assessed alcohol and cannabis use and motives for use. Multilevel models tested each aim.
resultsFor Aim 1, at the within-person level, longer prior-night sleep duration was associated with greater endorsement of depression-coping motives for alcohol, but only among those reporting relatively high levels of depression at baseline. Better prior-night sleep quality was associated with greater enhancement drinking motives the next day. For Aim 2, at the within-person level, longer prior night sleep duration was associated with lower enhancement motives for cannabis use.
conclusionEnhancement motives for alcohol and cannabis use change as a function of day-to-day changes in sleep duration and quality. Findings highlight the idea that treatment for sleep disturbance could influence substance use motives, perhaps thereby reducing subsequent use and related consequences.
