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

aimTo describe the outcomes of cannabis policy debates in Australia from 1967 to 2024.

methodsWe searched popular media, public reports, parliamentary inquiries and policy documents on cannabis in Australia since the 1960s and examined peer reviewed papers, national survey data and police records of cannabis-related arrests.

resultsWe describe three phases in the development of Australian cannabis policy: a prolonged debate (1970-1999) about whether state governments should remove criminal penalties for cannabis possession and use; a less prominent but overlapping debate (1994-2016) about whether Australia should legally permit the medical use of cannabis; and a renewed debate (1999-2023) about whether adults should be allowed to use cannabis for non-medical purposes and obtain it from a regulated legal market. The legalisation of medical cannabis in 2016, and the progressive liberalisation of its regulation, appear to have increased public support for adult cannabis legalisation in Australia and encouraged several so far unsuccessful attempts to pass legislation to do so.

conclusionsCriminal penalties for personal possession and use of cannabis have been removed in smaller states and territories of Australia, but the more populous states have diverted persons charged with cannabis use offences into education and treatment. The legalisation of medical cannabis use in 2016 appears to have increased public support for the legalisation of adult use, but there are major political obstacles to this policy change.
