Relationships Between Alcohol and Cannabis Policies in U.S. States, 1999-2019.
Article in Journal of studies on alcohol and drugs, 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
objectiveA crucial question regarding the public health impacts of cannabis legalization is its impact on alcohol consumption and alcohol-related harm. However, little is known about whether these changing cannabis policies are occurring in liberal or in restrictive alcohol policy environments, either of which likely affect public health outcomes. We constructed comprehensive state-level alcohol and cannabis policy indices and explored relationships between them.
methodWe assessed relationships between the Alcohol Policy Scale (APS) and the Cannabis Policy Scale (CPS) from 1999 to 2019. The APS and CPS were based on 29 and 17 state-level policies, respectively, and each policy was weighted for its relative efficacy and degree of state-year implementation.
resultsFrom 1999 to 2019, average state APS scores increased modestly (became more restrictive) by 4.11 points (2019
conclusionsAlthough cannabis policies liberalized rapidly from 1999 to 2019, alcohol policies stayed relatively stable and did not differ by degree of cannabis policy liberalization. In general, there were weak associations between cannabis and alcohol policies among states; however, there was some temporal, regional, and political variation.
