Sleep quality and duration following the use and co-use of alcohol and cannabis in the daily life of community adults.

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
backgroundSleep-promotion is one of the most common reasons people use cannabis. Previous studies, primarily among young adults, suggest that cannabis use has negligible day-level effects on sleep but may attenuate alcohol's negative effects when both substances are used. Studies among middle-aged/older adults are needed to determine the generalizability of these day-level associations.
methodsThis preregistered secondary data analysis examined daily-life associations between alcohol and cannabis use with next-day sleep quality and duration in a community sample of 48 adults (50 % female; age M=36.42, SD=10.96) reporting weekly alcohol and/or cannabis use. Participants completed ecological momentary assessments over 60 days. Multilevel models examined whether alcohol use, cannabis use, or alcohol-cannabis co-use (vs. no use) that day were associated with sleep quality and duration that night. Next, sleep quality and duration were examined as predictors of next-day craving and alcohol/cannabis use.
resultsCannabis use was associated with longer sleep duration than days of alcohol use, co-use, or no use, which were not different from one another. Sleep quality did not differ following alcohol/cannabis use. Sleep quality and duration were not associated with next-day craving for alcohol or cannabis. Longer sleep duration was associated with higher likelihood of next-day cannabis use.
conclusionsCommunity adults report sleeping ~15min longer on days of cannabis use, unless they also drank alcohol that day. This finding underscores the importance of examining co-use in daily life. Cannabis use demonstrated limited benefits for sleep, which should be evaluated in context with risk for increasing cannabis use over time.
