Simultaneous Alcohol and Cannabis Use With a Romantic Partner Present: Daily Associations With Drinking, Intoxication, and Consequences Among Young Adults.
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
objectiveSimultaneous alcohol and cannabis use (commonly referred to as SAM) represents a significant public health concern for young adults. Romantic partners are a strong source of influence on substance use; however, research on SAM use among young adults with romantic partners is sparse. Using daily data, we tested whether SAM use was more likely on alcohol use days with a romantic partner present (vs. without), and whether SAM use days (vs. alcohol-only use) with a romantic partner present were differentially associated with alcohol use outcomes and sexual behaviors.
methodA community sample of 308 young adults (ages 18-25) who reported at least one day of alcohol use with a romantic partner present completed six 14-day bursts of twice-daily surveys across 2 years. Participants completed daily measures on alcohol and SAM use, partner presence during use, subjective intoxication, positive and negative alcohol-related consequences, and sexual behaviors.
resultsOn alcohol use days with a partner present (vs. without), individuals were significantly more likely to report SAM use. On SAM use (vs. alcohol-only) days with a partner present, individuals reported consuming more drinks, greater subjective intoxication, more alcohol-related positive consequences, and a greater likelihood of sex while intoxicated. Reporting a greater proportion of SAM use days (vs. alcohol-only days) with a partner present across the entire study was significantly associated with overall greater subjective intoxication and a greater likelihood of having sex while intoxicated.
conclusionsThe presence of a romantic partner may increase the risk of engaging in SAM use at the daily level, and SAM use with a partner present is associated with high-risk drinking behaviors and more positive alcohol-related consequences compared with alcohol-only use.
