Assessment of nicotine and cannabis co-use among adolescents and the association with nicotine and cannabis dependence symptoms.
Article in Addictive behaviors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
significanceAdolescent nicotine and cannabis co-use is common, but prior studies use imprecise measurement of co-use which may not capture the most problematic behaviors such as same-day use.
methodsThis cross-sectional study examined patterns of nicotine and cannabis co-use among Southern California high school students in Fall 2022 (N = 3823). Participants were classified into five mutually exclusive past-month nicotine and cannabis use groups: 1) same-day co-use: use of both substances on the same day at least once; 2) past-month co-use: use of both without same-day use; 3) exclusive nicotine use; 4) exclusive cannabis use; 5) no use of either. Adjusted logistic regression models evaluated the association of co-use with any nicotine and/or cannabis dependence symptoms.
resultsOverall, 3.3% reported same-day co-use, 1.5% past-month co-use, 1.6% exclusive nicotine use, 3.1% exclusive cannabis use, and 90.5% no nicotine/cannabis use. Odds of cannabis dependence symptoms (aOR = 4.28, 95%CI[1.98-9.28]) were higher among the same-day vs. past-month co-use group, as were odds of nicotine dependence (aOR = 1.81, 95%CI[0.87-3.77]), though the result was not statistically significant. Compared to past-month co-use, exclusive cannabis use was associated with similar odds of cannabis dependence symptoms (aOR = 0.99, 95%CI[0.47-2.09]), while exclusive nicotine use was associated with non-significant lower odds of nicotine dependence symptoms (aOR = 0.42, 95%CI[0.17-1.04]).
conclusionAdolescents reporting same-day co-use had significantly greater cannabis dependence symptoms than those reporting past-month but not same-day use of both substances. Using a same-day definition of co-use might capture more problematic co-use behaviors.
