Association between state-level medical marijuana legalization and marijuana use during pregnancy: A population-based study.
Article in The American journal on addictions, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
BACKGROUND AND
objectivesDespite marijuana's association with adverse pregnancy and birth outcomes, its use during pregnancy increased over the last two decades. During this period, medical marijuana has been legalized in 38 states and the District of Columbia. States with legalized medical marijuana have observed increased marketing of marijuana and related products. This study aims to examine the association between state-level medical marijuana legalization and marijuana use during pregnancy in the United States.
methodsUsing the 2015-2021 National Survey on Drug Use and Health, we evaluated the association between marijuana use in the past month among currently pregnant mothers (N = 4338) and legalized medical marijuana in their state of residence. Survey-weighted descriptive, bivariate, and multivariable logistic regression analyzes were performed.
resultsAbout 5.7% of pregnant women reported using marijuana in the past month, and 59.0% lived in a state where medical marijuana was legalized across 2015-2021. Compared to those living in states without marijuana legalization, more pregnant women living in states with marijuana legalization reported using marijuana (4.6% vs. 6.5%). In the multivariable model, pregnant women residing in states with medical marijuana legalization were more likely to use marijuana than residents of states without legalization (adjusted Odds Ratio: 1.56; 95% Confidence Interval: 1.11-2.18). CONCLUSION AND SCIENTIFIC SIGNIFICANCE: This is the first known study to find that pregnant women living in states where medical marijuana is legalized are more likely to use marijuana during pregnancy. Pregnant women should be informed of adverse pregnancy and birth outcomes linked to marijuana use during pregnancy.
