The consequences of chronic methamphetamine use are already visible in hospital wards, and it’s about to get worse, an emergency department doctor says.
Dr Paul Quigley told a symposium on reducing drug harm on Monday the country was facing an impending health crisis on par with smoking-related lung disease.
“We are seeing the chronic effects of drug use, that’s often in terms of mental health – so people developing ongoing forms of schizophrenia – [but] we are now seeing the hard effects of long-term methamphetamine use.
“We’re seeing people with cardiomyopathies, heart failure.” Dr Paul Quigley.

Quigley told RNZ methamphetamine was particularly “cardio-toxic”, affecting the heart in two key ways through accelerated ageing and exhaustion.
He said the ageing heart meant heart disease was showing up 10 to 15 years earlier than expected.
“So we’re seeing people in their mid-40s who are regular methamphetamine users having heart attacks as if they’d be in their 60s.”
He said meth also increased people’s heart rate and blood pressure, and sustained use literally “exhausts the heart” resulting in cardiomyopathy (a type of heart failure) and in extreme cases, heart transplants.
Quigley said those most at risk of heart disease weren’t “your weekend warriors”, but almost daily methamphetamine users who’d been using for more than a decade.
He said data showed acute meth use in New Zealand was on the rise and the major concern was the impending burden on the healthcare system and society – a cost already seen in countries where meth use was high.

“You should look at this like smoking. People smoked in the 40s and 50s … then later we had this terrible burden of lung disease from the effects of smoking. And it’s going to be the same.
“If we have increased meth use now, we should be looking at, ‘Well, what’s going to happen in 10 to 15 years time?’
“We’re going to have this much larger population of patients with these heart conditions … and it’s affecting parts of our society that are already struggling,” he said.
“We’ve just got through the smoking crisis – in terms of lung disease is decreasing – but it’s just going to be replaced by this new disease.”
The Reducing Drug Harm in Aotearoa Symposium – hosted by the Public Health and Forensic Science Institute – featured a range of experts from the frontline of festival drug checking and wastewater analysis, to the police’s drug intelligence office and international experts on early warning systems for new and harmful drugs.
National Drug Intelligence Bureau analyst Kylie Collins spoke to current and emerging drug trends in New Zealand, highlighting a spike in meth consumption in July 2024 that almost doubled methamphetamine use nationally – and has continued.
Collins said the vast majority of New Zealand’s supply came from overseas and the increased use had coincided with a drop in price for the drug.
She said alongside increasing seizures of the drug, meth-related hospitalisations had also been on the rise.
“However, many hospitalisations stem from chronic or very heavy use. So with the recent increases in meth consumption we expect to see even bigger increases in hospitalisations in years to come.”
