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

backgroundCannabis users have been stigmatized in the course of the long-standing prohibition. A recent law change in Germany made cannabis possession and cultivation legal for recreational use, potentially impacting stigmatization. This article aims to quantify the experience of perceived and self-stigma related to cannabis use before the law change and to explore associations with sociodemographic-, cannabis use pattern- and psychological distress-related items.

methodsParticipants were recruited in 2023 from ISO-certified online access panels. A subsample of n = 684 regular (at least monthly) cannabis users was selected through quota-sampling based on age, gender, education, and federal state to reflect the demographic composition of the German population aged 18-64. A standardized online-questionnaire covering sociodemographics, health-related variables, cannabis use (frequency, purpose) as well as experiences of external and self-stigmatization was employed. Descriptive data analyses were performed utilizing the stigma-related items as outcome variables.

resultsExternal Stigmatization was perceived by 30.6%, while 22.1% reported self-stigma concerning their cannabis use. Higher education, high psychological distress, medical use, and cannabis use disorder (CUD) were significantly associated with both external stigmatization and self-stigma. Respondents speaking publicly about their cannabis use show higher shares of external and self-stigma. Having been in trouble with the police regarding cannabis was positively associated with both types of stigmatization.

conclusionGerman residents who use cannabis at least monthly perceived external stigmatization and self-stigma related to cannabis consumption at a relevant level. As medical users and those with CUD are particularly affected, healthcare providers should be sensitized to the issue of stigmatization.
