Decriminalization thresholds for drug possession: A multi-criteria policy analysis framework.

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
backgroundDecriminalization of personal possession of drugs has been proposed as an approach to mitigate the harms of drug prohibition. Despite growing interest, particularly in Canadian settings, analyses of approaches to defining the parameters of what constitutes personal possession within decriminalization models are lacking. Using the Province of British Columbia, Canada, as a case study, we undertook an evidence-based multi-criteria policy analysis of three models for defining personal possession: 1) a model that defines personal possession as the absence of evidence of drug trafficking; 2) a cumulative threshold of 15 grams; and 3) a cumulative threshold of 2.5 grams.
methodsWe utilized data from four sources: qualitative interviews with 16 experts, including representatives from government and law enforcement; Vancouver Police drug seizure data; self-reported drug consumption data from longitudinal cohorts of people who use drugs in Vancouver; and publicly available government documents (e.g., the Government of BC's submission for decriminalization). Data was used to identify and define evaluation criteria which reflect the stated policy objectives of decriminalization alongside other policy considerations. This framework was used to conduct a multi-criteria policy analysis of the three different models.
resultsThe seven evaluation criteria included: 1) reduction in interactions with police; 2) reduction of police drug seizures; 3) coverage for those with high consumption; 4) impact on equity-deserving groups; and acceptance on the part key stakeholders, including: 5) people who use drugs; 6) law enforcement; and 7) the public. The model that performed the best was the cumulative threshold model of 15 grams.
conclusionFindings highlight that different threshold models advance and constrain the stated policy objectives of drug decriminalization to varying degrees. This analysis provides a framework that other jurisdictions considering decriminalization could use to help inform determinations of threshold levels based on stated policy objectives.
