Rating the comparative efficacy of state-level cannabis policies on recreational cannabis markets in the United States.
Article in The International journal on drug policy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundCannabis policy is developing faster than empirical evidence about policy effects. With a panel of experts in substance use policy development and research, we identified key cannabis policies and their provisions enacted by U.S. states; rated their theoretical efficacy in a restrictive form for reducing problematic use and impaired driving in the context of a recreational cannabis market as judged by experts; and rated the strength of evidence for each policy.
methodsUsing a modified Delphi approach, 9 panelists rated the comparative efficacy of 18 state cannabis policies for reducing youth use of cannabis, excessive cannabis use among the general population, and cannabis-impaired driving. Each outcome was rated separately using a Likert scale, and panelists also rated the strength of evidence supporting each efficacy rating. Investigators provided descriptions of each policy so that the nine panelists had similar conceptions of each policy.
resultsState monopoly (state owns all production, manufacturing, wholesale, and retail operations) was rated as the most effective policy for all three outcome areas. Restrictions on retail physical availability, taxes, retail price restrictions, and retail operations restrictions were also highly rated for all three outcomes. Policies regulating cannabis businesses and products were judged more effective than policies targeting consumer use and behavior. Panelists reported there was little or no direct evidence from the cannabis policy literature for most of the included policies.
conclusionThese ratings can facilitate research as well as policy-making decisions. A relatively small number of policies were judged to be highly effective across all three domains, indicating that for the most part adult excessive use, youth use, and impaired driving can all be reduced with the same set of policies; these policies tended to target the behaviors of businesses rather than consumers. The low levels of direct evidence available to inform policy ratings, as reported by the policy panelists, makes clear the need for ongoing and sustained cannabis policy research.
