Otago Researchers Call for Misuse of Drugs Act Reform: Urging Modernization to Reduce Harm

University of Otago researchers are at the forefront of a growing movement to overhaul New Zealand's outdated drug legislation. In a compelling briefing released earlier this year, experts from Otago's Department of Public Health have joined forces with the New Zealand Drug Foundation to declare the Misuse of Drugs Act (MODA) of 1975 a 'colossal failure.' This 50-year-old law, they argue, has failed to curb drug use while exacerbating harms through criminalization rather than supporting health-led interventions.

Dr. Rose Crossin, a senior researcher at Otago's Christchurch campus, has been instrumental in highlighting these issues. Her work underscores a consensus among academics that modernizing drug policy is essential for reducing overdose deaths, addiction rates, and social inequities, particularly for Māori communities disproportionately affected by current approaches.

The Origins and Framework of the Misuse of Drugs Act

The Misuse of Drugs Act 1975 was enacted during a global 'war on drugs' era, classifying substances into classes A, B, and C based on perceived harm and potential for abuse. Class A drugs like heroin and methamphetamine carry the harshest penalties, up to life imprisonment for supply, while possession can lead to fines or jail time. This punitive model aimed to deter use but has seen minimal updates despite evolving drug markets and scientific understanding.

Over decades, amendments have introduced elements like police diversion for minor possession and drug checking at festivals, but the core criminal justice focus remains. Otago researchers point out that this structure ignores poly-drug use realities and novel psychoactive substances (NPS), leaving gaps in harm prevention.

Evidence Mounting Against the Status Quo

Recent data reveals the Act's ineffectiveness. Accidental drug overdose deaths have surged more than thirteen-fold since 1988, with 1,295 recorded between 2016 and 2024 alone. Opioids dominate, involved in most cases, often alongside alcohol (43% of overdoses) and benzodiazepines, with poly-substance use in over half of fatalities.

Māori face a mortality rate 2.8 times higher than non-Māori, and males comprise 63.5% of deaths. Non-fatal hospitalisations for poisonings hit 582 in 2024, with stimulants rising since 2020. Despite this, low-level possession convictions persist—3,274 drug offences in 2022, 56% for personal use—diverting resources from health services.

Otago's drug harms ranking study further dismantles the Act's classifications, showing alcohol as New Zealand's most harmful drug, followed by methamphetamine and tobacco—many legal despite high societal costs nearing $2 billion annually from illicit drugs alone.

Otago's National Addiction Centre: Leading the Research Charge

The University of Otago's National Addiction Centre (NAC) in Christchurch has produced groundbreaking work informing reform calls. Dr. Crossin's 'New Zealand's Choice: Funding Our Drug Policy' report reveals government spending: 68% on law enforcement, 25% treatment, 6% prevention, and just 1% harm reduction—contrasting sharply with public preferences for 36% enforcement and balanced health investments.

Deliberative workshops showed bipartisan support for shifting funds, even among law-and-order advocates. NAC's multi-criteria harms analysis and youth surveys emphasize prevention needs, positioning Otago as a hub for evidence-based policy.National Addiction Centre research overview

Unpacking the Funding Crisis

Illicit drugs inflict nearly $2 billion in annual harm, yet the $500 million government response prioritizes policing over health. Otago research via deliberative methods found communities favor reallocating to treatment (24%), prevention (25%), and harm reduction (16%). This mismatch fuels cycles of arrest and stigma, hindering access to support.

Crossin advocates a Citizens' Assembly to bridge this gap, ensuring policies reflect societal values.

Vision for a Modern Framework

Otago experts propose repealing MODA for a health-centered law: decriminalize personal possession/use, regulate high-harm supply, and scale harm reduction like naloxone access and drug checking. Systems approaches would connect interventions, prioritizing equity for Māori and youth.

• Decriminalization to reduce criminal records' lifelong impacts.
• Investment in evidence-based prevention/treatment.
• National overdose surveillance and Good Samaritan laws.

International Lessons: Portugal's Success Story

Portugal's 2001 decriminalization offers a blueprint. Treating use as administrative, not criminal, slashed overdose deaths (80 to 16 annually), HIV from injecting by over 90%, while use rates stayed low—below European averages. Health referrals increased, stigma decreased. Similar shifts in Oregon and Canada show promise, contrasting NZ's rising harms.

Stakeholder Perspectives and Challenges

The briefing unites Otago academics, NZ Drug Foundation, Harm Reduction Coalition Aotearoa, and public health leaders. Māori advocates stress cultural contexts, while police support diversion. Challenges include political inertia and moral panics, but cross-party evidence could drive change.

For university students facing drug pressures, Otago's research informs campus harm reduction, vital amid O-Week incidents.

Higher Education's Stake in Drug Policy Reform

Outlook and Actionable Steps

With overdose trends stubborn and youth at risk, 2026 presents a reform window. Otago urges politicians for a health framework, Citizens' Assembly, and funding shifts. Individuals can petition, support drug checking, or pursue studies in addiction science.
