Impact of self-reported cannabis use on veterans' intensive PTSD treatment outcomes.

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
objectiveThe impact of cannabis use on evidence-based posttraumatic stress disorder (PTSD) treatment outcomes remains inconclusive. Further, few studies to date have examined these relationships in intensive PTSD treatment settings, with existing literature being similarly inconclusive. The present study assessed the role of cannabis use frequency prior to and concurrent with treatment on self-reported PTSD and depressive symptoms in two samples of veterans undergoing distinct (3-week and 2-week) Cognitive Processing Therapy-based intensive treatment programs (ITPs;
methodCannabis use frequency over the past 2 weeks was self-reported by veterans. PTSD and depression symptoms were assessed before, during, and following the ITP using the PTSD Checklist for the
resultsIndividuals in the 3- and 2-week ITPs reported low rates of cannabis use prior to and concurrent with treatment. Across models, frequency of cannabis use was not significantly related to PTSD symptoms over time. Findings surrounding the impact of cannabis use on depressive symptom severity were only found in the 2-week ITP and not replicated in the 3-week ITP.
conclusionInfrequent and/or recreational cannabis use frequency prior to or concurrent with treatment did not meaningfully impact intensive PTSD treatment outcomes. Findings associated with concurrent use need to be interpreted with caution due to the small subsample. Future research should explore whether more frequent cannabis use and the dosage differentially impact PTSD treatment outcomes. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
