Impact of Simple Versus Complex Cannabis Advertising Messages and Warnings on US Young Adults' Product Perceptions.
Article in Substance use & addiction journal, 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
backgroundDespite cannabis' increased popularity, limited research has assessed effects of advertising messages or warnings, particularly their complexity. This study examined effects of advertising message and warning complexity on young adults' perceptions.
methodsIn 2024, US adults ages 18 to 34 (n = 3581; 40.8% past-month cannabis use) completed an online survey-based experiment using a 2 × 3 factorial design (advertising message: simple vs complex; warning: none vs simple vs complex), then reported perceived addictiveness, harm, cautiousness, appeal, and interest (0 = none - 7 = extremely). Multivariable regression assessed conditions and their interactions with 1 another and past-month use in relation to perception outcomes.
resultsComplex (vs simple) advertising message exposure was associated with higher perceived addictiveness (
conclusionsDesired effects were yielded by complex advertising messages (interest, appeal) and warnings (risk). However, complex advertising messages may overpower effects of complex warnings among users. Additional research is needed to understand these dynamics and inform regulations.
