1 · What the graph read from it

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.

2 · The registry

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

backgroundCannabis cessation or reduction may increase cross-substance substitution in response to craving or reduced use. Evidence for substitution is mixed, and treatment effects remain unclear. This exploratory study examined alcohol and tobacco substitution within clinical trials of cannabis cessation.

designData were pooled from 829 participants (Mage = 27.1, SD = 9.1; 31 % female; 63 % White; 13 % Latine/Hispanic) across seven pharmacologic cannabis use disorder (CUD) trials. Weekly cannabis, alcohol, and cigarette use were assessed (cigarettes in six trials). Longitudinal mixed-effects models tested whether cannabis use or craving predicted next-week alcohol and cigarette outcomes, with treatment condition included as a moderator.

resultsNo significant three-way interactions with treatment emerged. Cannabis craving interacted with cannabis frequency to predict modest increases in next-week alcohol quantity (b = 0.009, p = 0.04970497), although not drinking frequency. Higher cannabis quantity predicted lower next-week cigarette quantity (b =  - 0.009, p = 0.042). There was limited evidence of a treatment × craving interaction for cigarette frequency (b =  - 0.008, p = 0.04990499), with higher craving associated with fewer smoking days in the active treatment arm.

conclusionsAlcohol findings were consistent with complementary use patterns, whereas cigarette smoking showed evidence of both concurrent coco-use and prospective substitution with cannabis. Pharmacotherapy did not broadly alter these relationships; however, among participants receiving active treatment, greater cannabis craving was associated with fewer smoking days. These findings provide initial evidence supporting monitoring of polysubstance use during CUD treatment and consideration of how cessation efforts may differentially affect alcohol and tobacco use.
