Perceived risk of illicit drug consumption in singapore: findings from a nationwide survey.
Article in Social psychiatry and psychiatric epidemiology, 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
backgroundThis study aimed to identify groups of risk perception of illicit drug consumption and associated sociodemographic and mental health factors in Singapore.
methodsA representative sample of 6,509 Singapore citizens and permanent residents aged 15 to 65 years was randomly selected for participation over 14 months. Information on perceived risk related to illicit drug consumption, and correlates were collected via questionnaires. Data were analysed using latent class analysis to identify risk perception profiles. Logistic regression analyses were performed to determine the sociodemographic and mental health correlates across different risk perception profiles.
resultsFour profiles emerged; high risk perception across all substances and frequencies, low risk perception across all substances and frequencies, low risk perception of cannabis, and low risk perception of occasional illicit drug consumption. About 9.4% (n = 557) reported low risk perception of cannabis. Males (vs. females, RR: 2.15, 95% CI: 1.57-2.94) were more likely to have a low risk perception of cannabis. Those aged 35-65 years (35-49 vs. 15-34, RR: 0.37, 95% CI: 0.25-0.54; 50-65 vs. 15-34, RR: 0.19, 95% CI: 0.10-0.37), with secondary school (vs. degree and above, RR: 0.23, 95% CI: 0.13-0.39) or pre-tertiary (vs. degree and above, RR: 0.42, 95% CI: 0.29-0.61) education were less likely to have a low risk perception of cannabis. Ever-smokers (vs. non-smokers, RR: 1.86, 95% CI: 1.31-2.64), and those grouped as "safe drinking" (vs. abstainers, RR: 3.80, 95% CI: 2.50-5.77) or "hazardous drinking" (vs. abstainers, RR: 7.00, 95% CI: 3.69-13.28) were more likely to perceive low risk of cannabis. Individuals with a low risk perception across all substances and profiles were more likely to report symptoms of anxiety (OR: 7.17, 95% CI: 1.31-38.98) when compared to high risk perception across all substances and frequencies individuals.
conclusionsThese findings provide critical insights for tailoring prevention and education initiatives to address substance use behaviours in Singapore.
