Developing an online cannabis store paradigm for Cannabis Regulatory Science.
Article in medRxiv : the preprint server for health sciences, 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
Background: The legal cannabis industry is using online point-of-sale marketing, but few tools exist for evaluating how this marketing influences consumer behavior. To address this gap, we developed the Platform for Online Evaluation of Marijuana Marketing and Sales (POEMMS), a realistic, customizable online cannabis store. This study tested the feasibility, usability, and ecological validity of POEMMS. Methods: U.S. adults aged 18+ were recruited via social media advertisements. Participants engaged in a simulated shopping task using POEMMS and then completed a post-shopping survey. Participants were instructed to imagine having no cannabis and to buy products as they would in real life. Survey measures included typical real-world cannabis spending and 0-10 Likert ratings of the store's usability and realism. Spearman correlations tested associations between in-store and self-reported spending. Results: N=678 completed the shopping task. Approximately 58% used cannabis daily. Median total spending was $100. Shopping task spending and self-reported spending for flower, open concentrates, cartridges, and edibles were strongly correlated (rs = 0.74, 0.74, 0.67, 0.62, respectively; all p<0.001). Participants rated the store as easy to navigate (Median=10) and product characteristics easy to find (Median=10). Perceived realism was also high across product names, types, potency, and descriptions (Median=8-10). Conclusions: POEMMS elicited behaviorally and perceptually valid responses in a large national sample of cannabis users. Findings demonstrate the platform's utility for Cannabis Regulatory Science by allowing controlled evaluation of online marketing effects. Future applications of POEMMS could generate evidence to inform cannabis marketing policy and regulation.
