Claim
This measure will allow people with small amounts to avoid arrest.
Correction

This is outdated. Oregon reversed Measure 110’s decriminalization, and possession of small amounts of controlled substances was recriminalized effective September 1, 2024.

Full reasoning

Oregon's Ballot Measure 110 did reduce penalties for possession of small amounts of controlled substances when it took effect on February 1, 2021. But that is no longer the current law. The State of Oregon now says House Bill 4002 repealed the relevant Measure 110 provisions effective September 1, 2024. That means the article's present-tense statement that the measure will allow people with small amounts to avoid arrest is no longer accurate.

Claim
At present, opium poppies are mostly grown in Afghanistan (224,000 hectares (550,000 acres)), and in Southeast Asia
Correction

This is outdated. UNODC now reports that Myanmar is the world’s largest opium producer, while Afghanistan’s opium poppy cultivation fell to about 10,200 hectares in 2025, not 224,000 hectares.

Full reasoning

The article presents this as a current fact ('At present'), but current UNODC data contradict it.

  • UNODC's Afghanistan Opium Survey 2025 says the total area under opium poppy cultivation in Afghanistan in 2025 was 10,200 hectares, down sharply from pre-ban levels.
  • UNODC's Myanmar Opium Survey 2025 says Myanmar had 53,100 hectares under opium poppy cultivation in 2025.
  • UNODC's World Drug Report 2026 states that Myanmar is now the world's largest opium producer, followed by Afghanistan.

So the article's present-tense statement that opium poppies are 'mostly grown in Afghanistan' and its specific figure of 224,000 hectares are no longer accurate.

  • Afghanistan Opium Survey 2025

    The total area under opium poppy cultivation in 2025 was estimated at 10,200 hectares, 20% lower than in 2024 (12,800 hectares) and a fraction of the pre-ban levels recorded in 2022, when an estimated 232,000 hectares were cultivated nationwide.

  • Myanmar Opium Survey 2025

    In 2025, the area under opium poppy cultivation in Myanmar was estimated at 53,100 hectares. That is a 17% increase from the 45,200 hectares estimated to be under cultivation in 2024.

  • WDR 2026 | Data Portal UNODC

    Myanmar is now the world’s largest opium producer, followed by Afghanistan, Mexico and the Lao People’s Democratic Republic.

Claim
Some Australian cities (such as Sydney) have instituted legal diamorphine supervised injecting centers, in line with other wider harm minimization programs.
Correction

Sydney’s facility is a supervised injecting centre, not a legal diamorphine-prescription centre. NSW says clients inject their own pre-obtained drugs there; the clinic does not provide drugs.

Full reasoning

This sentence conflates two different things:

  1. Diamorphine prescription / heroin-assisted treatment, where a medical service provides prescribed diamorphine; and
  2. Supervised injecting centres, where people bring and inject their own drugs under medical supervision.

NSW Health describes the Sydney Medically Supervised Injecting Centre as a place where people who intend to inject their own drugs can do so more safely. A current service description for the same centre likewise says that drugs are not provided at the clinic. So calling Sydney's service a 'legal diamorphine supervised injecting center' is incorrect.
