The impact of cannabis use proximal to sleep and cannabinoid metabolites on sleep architecture.
Article in Journal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
STUDY
objectivesCannabis is a common sleep aid; however, the effects of its use prior to sleep are poorly understood. This study aims to determine the impact of nonmedical whole plant cannabis use 3 hours prior to sleep and measured cannabis metabolites on polysomnogram measures.
methodsThis is a cross-sectional study of 177 healthy adults who provided detailed cannabis use history, underwent a 1-night home sleep test and had measurement of 11 plasma and urinary cannabinoids, quantified using mass spectroscopy, the morning after the home sleep test. Multivariable models were used to assess the relationship between cannabis use proximal to sleep, which was defined as use 3 hours before sleep, and individual home sleep test measurements. Correlation between metabolite concentrations and polysomnogram measures were assessed.
resultsIn adjusted models, cannabis use proximal to sleep was associated with increased wake after sleep onset (median 60.5 vs 45.8 minutes), rate ratio 1.59 (1.22, 2.05), and increased proportion of stage 1 sleep (median 15.2% vs 12.3%), effect estimate 0.16 (0.06, 0.25). Compared to nonusers, frequent cannabis users (> 20 days per month) also had increased wake after sleep onset and stage 1 sleep, in addition to increased rapid eye movement latency and decreased percent sleep efficiency. Δ9-tetrahydrocannabinol metabolites correlated with these home sleep test measures.
conclusionsCannabis use proximal to sleep was associated with minimal changes in sleep architecture. Its use was not associated with measures of improved sleep including increased sleep time or efficiency and may be associated with poor quality sleep through increased wake onset and stage 1 sleep.
