Accuracy of labeled THC potency across flower and concentrate cannabis products.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
High total tetrahydrocannabinol (THC) cannabis products are quickly gaining market share across the U.S., but it is unknown whether labeled cannabinoid content accurately reflects true product potency. This study aimed to assess discrepancies between labeled and observed THC content in flower and concentrate products. A representative sample of 277 cannabis flower (n = 178) and concentrate (n = 99) products were purchased from 52 Colorado dispensaries and analyzed for THC content. Products were classified as accurately labeled if observed THC was within ± 15% of labeled THC, and comparative analysis tested observed versus labeled THC content. Labeling accuracy for THC content depended on product type (X
