Cannabis use and alcohol and drug outcomes in a longitudinal sample of sober living house residents in California.
Article in Journal of substance use and addiction treatment, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionSome evidence suggests that cannabis may be a safer substitute for other drugs. Historically, sober living houses (SLHs) have been abstinence-based environments designed for individuals in recovery to live with others in recovery. However, the evolving legal landscape around cannabis use has left SLH operators and managers in a difficult position regarding policies related to cannabis use among residents. The primary aim of this study was to examine how cannabis use relates to alcohol use, other drug use, and related problems among SLH residents.
methodsBaseline (N = 557), 6-month (n = 462), and 12-month (n = 457) data came from SLH residents living in 48 houses in Los Angeles, CA from 2018 to 2021. Longitudinal generalized estimating equation models tested associations between any past six-month cannabis use and alcohol and non-cannabis drug outcomes: any use, number of days of use, and any alcohol- or drug-related problems. Final models adjusted for baseline age, sex, race-and-ethnicity, inpatient substance use treatment, and alcohol/drug use days, and time-varying 12-step attendance and percent of social network using drugs/alcohol heavily.
resultsAt baseline, 107 (19.2 %) residents reported cannabis use in the past six months. At 12 months, 80 (17.5 %) residents reported cannabis use in the past six months. Across all timepoints, any vs. no past six-month cannabis use was related to significantly (P < 0.05) higher odds of past-month alcohol use (OR = 3.85, 95 % CI: 2.65, 5.59); more drinking days in the past six months (IRR = 1.76, 95 % CI: 1.40, 2.21); higher odds of alcohol problems (OR = 2.74, 95 % CI: 1.99, 3.76); higher odds of past-month drug use (OR = 10.41, 95 % CI: 6.37, 17.00); more drug use days in the past six months (IRR = 1.86, 95 % CI: 1.40, 2.49); and higher odds of drug problems (OR = 14.99, 95 % CI: 9.91, 22.68).
conclusionsDuring each assessment period, almost one-fifth of individuals residing in sample of California sober living houses report using cannabis in the past six months. Cannabis does not appear to work as a substitute for alcohol or other drugs in this population because cannabis use is related to increased risk of alcohol and other drug use and problems. SLH managers and operators should consider potential harm that could result from house policies that fail to address cannabis use.
