Marijuana Use and Its Impact on Outpatient Anesthesia.
Review in Anesthesia progress, 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
Cannabis is one of the most common psychoactive substances used worldwide, and its use is increasing. Modern products vary widely in tetrahydrocannabinol (THC) concentrations and usage routes, creating challenges for anesthesia providers. This review summarizes current evidence on the pharmacology, pharmacokinetics, physiologic effects, and perioperative considerations of cannabis to help guide safe anesthetic management of cannabis-using patients. Cannabis contains over 100 phytocannabinoids, chiefly psychoactive Δ9-THC and nonpsychoactive cannabidiol (CBD), which act on cannabinoid type-1 (CB1) and type-2 (CB2) receptors. Chronic use downregulates CB1 signaling, contributing to tolerance, dependence, and withdrawal. Cannabis exerts widespread physiologic effects, including neuropsychiatric complications, cardiovascular changes, respiratory issues, delayed gastric emptying, appetite stimulation, and reproductive endocrine disruption. Cannabis use has been associated with increased propofol requirements, possibly via cytochrome P450 enzyme induction and CB1 receptor downregulation. It may also alter responses to opioids, ketamine, and gabapentinoids, and chronic users often report higher postoperative pain. Cannabis use influences anesthetic dosing, airway and cardiovascular stability, and postoperative pain control. Thorough preoperative assessment, individualized anesthetic planning, and vigilant monitoring are essential, and further research is needed to establish evidence-based perioperative guidelines.
