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

backgroundDespite extensive research on the broader effects of recreational cannabis legalization (RCL), limited attention has been given to its impact on cannabis use disorder (CUD) treatment outcomes. This study addresses this gap by analyzing CUD treatment outcomes, including 90-day treatment retention and successful discharge.

methodsData were collected from a dataset of all publicly funded cannabis use disorder treatment delivered in California between January 2010 and December 2021 (n = 192,580). RCL’s impacts on CUD treatment outcomes was estimated using an individual-level pre-post time series model, including individual and county-level characteristics via logistic regression.

resultsCalifornia’s RCL was associated with a significant decrease in the probability of 90-day treatment retention and also of successful discharge from treatment for patients with a CUD. RCL was also associated with a decrease in the probability of 90-day CUD treatment retention for adults ages 21 + and White Non-Hispanics, and a decrease in the probability of successful discharge for White Non-Hispanics, and an increase in the probability of successful discharge for males and adults ages 21+. We find no association between RCL and treatment retention or successful discharge for Black Non-Hispanic or Hispanic patients.

conclusionsThe implementation of California’s RCL was associated with a decline in CUD treatment outcomes. The findings underscore the need for ongoing evaluation of cannabis legalization’s effects on public health to inform policy and practice in the context of evolving cannabis regulations.
