Associations Between Violence and Unsafe Living Situations With Cannabis Use During Early Pregnancy.
Article in Substance use & addiction journal, 2026. 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
backgroundMaternal and child health are adversely impacted by experiences of violence, unstable living situations, and cannabis use during pregnancy. Women who experience intimate partner violence (IPV) are more likely to use cannabis than those who do not experience IPV. However, IPV can be difficult to identify as patients may not be ready to disclose. As IPV is associated with prior experiences of violence and unsafe/unstable housing, this study aimed to estimate the associations between experiences of current IPV, any past-year violence, and unsafe or unstable living situations with cannabis use during early pregnancy. This study used a large, diverse sample to further our understanding of the relationship between violent experiences and prenatal cannabis use.
methodsUsing data from 303 178 pregnancies in California from 2014 to 2023, we used chi-square tests and modified Poisson regression models to estimate associations between experiences of current IPV, past-year violence, and unsafe/unstable living situations with cannabis use during early pregnancy.
resultsIndividuals endorsed current IPV or any past-year violence in <1% of the pregnancies (n = 324 [0.1%] and n = 979 [0.3%], respectively), and about 2% (n = 6284) reported having unsafe/unstable living situations. Over two-thirds (69.1%) of the pregnancies where patients endorsed current IPV also endorsed past-year physical violence or unsafe/unstable living situation. Individuals used cannabis during 7.2% (n = 21 868) of the pregnancies. In unadjusted analyses, current IPV, past-year violence, and unsafe/unstable living situations were associated with higher prenatal cannabis use. In adjusted analyses, past-year violence and unsafe/unstable living situations were associated with higher prenatal cannabis use.
conclusionsIt is crucial for experiences of violence and unsafe living situations to be concurrently assessed and addressed with cannabis use. Interventions that incorporate education, advocacy, and connections to mental health and IPV services could help reduce cannabis use and recurrent violence and improve pregnancy-related outcomes and patient safety.
