Use of cannabis to regulate negative affect in pregnancy: Bidirectional findings from an ecological momentary assessment study.
Article in Psychology of addictive behaviors : journal of the Society of Psychologists in Addictive Behaviors, 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
objectivePrenatal cannabis use is increasing in the United States, despite evidence of potential harms to pregnant individuals and their offspring. Elevated rates of anxiety and depression among those who use cannabis during pregnancy suggest that mental health difficulties may contribute to prenatal cannabis use. In line with the affect regulation hypothesis, many pregnant individuals endorse using cannabis to manage mood. However, no studies have examined this relationship in real time. Moreover, the acute effects of cannabis on mood during pregnancy remain understudied, limiting knowledge of whether negative affect (NA) relief reinforces continued use. Addressing these gaps, the present study examines the relationship between momentary NA and cannabis use in pregnant adults and explores the effect of cannabis on NA.
methodsParticipants (
resultsGeneralized linear mixed-effects models tested whether momentary ratings of depression, anxiety, and irritability predicted subsequent cannabis use (Aim 1), and linear mixed-effects models tested whether cannabis use predicted subsequent changes in NA (Aim 2). Aim 1 results indicated that greater levels of NA (momentary depression, anxiety, and irritability) were associated with greater odds of using cannabis. Aim 2 results suggest cannabis use was followed by reductions in depression, anxiety, and irritability, reflecting short-term NA relief.
conclusionsFindings provide the first real-time evidence supporting the affect regulation hypothesis in pregnancy and highlight the potential reinforcing role of NA relief in sustaining prenatal cannabis use. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
