1 · What the graph read from it

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.

2 · The registry

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

backgroundGermany experienced a steady rise in the prevalence of past-12-months cannabis use from 2012 to 2021. In 2024, cannabis was partially legalized for recreational use. Against this background, it is important to systematically examine consumption patterns in the early phase after legalization.

methodsData are from the 2012 (n2012 = 9084), 2015 (n2015 = 9204), 2018 (n2018 = 9267), 2021 (n2021 = 9046), and 2024 (n2024 = 7534) waves of the Epidemiological Survey of Substance Abuse (ESA), a repeated cross-sectional survey of Germanspeaking adults in private households.

resultsThe prevalence of past 12-month cannabis use rose steadily from 4.6% in 2012 to 8.8% in 2021. The prevalence in 2024 was 9.8%, an additional increase compared to 2021, but the difference is not statistically significant. Most cannabis users consumed marijuana (92.3%), predominantly in the form of joints (88.6%). One-quarter of them (25.7%) also belonged to a cannabis social club. The most frequently stated motivation for using cannabis was "to get high or have fun" (66.8%), followed by "to reduce stress or relax" (61.3%).

conclusionIn the early post-legalization period, there was a small, non-significant increase in the prevalence of cannabis use in Germany compared with 2021. Given the legalization is very recent, it is too soon to observe any clear effect.
