Data from Australia Wastewater Drug Monitoring Program suggests that the usage of methamphetamine (also referred to as speed, ice or crystal meth) is at a record high. Cocaine can also be up. MDMA levels might be depleted. Heroin is volatile.
At first glance, these results from Australian Criminal Intelligence Commission This week sounds dangerous.
But before we draw any big conclusions about what makes drug use worse, it is vital to take a better have a look at what these data can and may’t tell us.
What does wastewater data actually measure?
Wastewater testing works by analyzing sewage for traces of medicine that folks have used. Researchers test samples from treatment plants to estimate how much of the drug has been ingested by the population connected to the system.
It measures the quantity of metabolized drugs. So it’s price telling the difference between drugs which were flushed down the bathroom and medicines which were excreted.
This is a clever approach that avoids a few of the problems with self-report surveys, where people may underreport illegal behavior.

It also provides real-time data contrast. Population surveys that are held only every few years.
But wastewater data can only measure the amount of medicine used, not the number of people that use them or the extent of harm they cause.
Wastewater data cannot distinguish quantity from frequency. When it shows a rise in certain drugs, we do not know if more individuals are using the drug, or if the identical individuals are using more, or more often.
It also cannot discover whether the changes are resulting from overpurification.
So once we hear that methamphetamine use is at a “ten-year high”, what it really means is that the overall amount detected is high, not necessarily that more Australians are using methamphetamine, or that harms are increasing.
Are these results consistent with other data?
National surveys, treatment data, hospital presentations, police arrests and wastewater data all track it. Different parts of the drug system at different time points. And they do not at all times move in the identical direction at the identical time.
Long lasting Population survey data Shows a decline within the prevalence of methamphetamine use over the past 15 years. Other statistics show that casualties have increased, similar to more people Need treatment? And more Ambulance call-outs for methamphetamine. We have also seen a shift towards this. A more powerful form Drugs and more intense use amongst a small group of individuals.
This pattern suits with the rise in wastewater.
The same caution applies to cocaine. The wastewater data show a gradual increase, but we cannot tell whether this reflects increased use by individuals who already use cocaine, or a rise in recent users.
Based on other data – incl National Drug Strategy Household Surveywhich shows a rise in people trying drugs – it’s more likely to be each.
Can prescriptions affect data?
An issue that always comes up is whether or not increasing stimulant prescriptions, similar to those used to treat attention deficit hyperactivity disorder (ADHD), can affect wastewater results.
There has been one Significant increase Prescription amphetamines similar to short- and long-acting dexamphetamine for ADHD.
Dirty water cannot easily distinguish between illegal and prescribed amphetamines.
But the dimensions of the rise in methamphetamine use can’t be explained by prescription use alone.
MDMA leveling off
The wastewater report suggests that MDMA use could also be leveling off after earlier peaks. This is consistent with what we find out about drug markets.
MDMA follows social patterns. It rises with nightlife and festival culture, and falls when that atmosphere changes. We saw a Major shortages during pandemics When access to each MDMA and festivals was greatly reduced.
There were early signs of this. On the increase A re-plateau may reflect a stable market following the post-pandemic recovery.
Heroine is different.
Heroin shows a more uniform pattern. lower than 1% of the population uses heroin. But they use it commonly for a very long time.
Fluctuations in heroin use occur when there are changes in supply, purity, or the provision of treatments similar to opioid substitution therapy similar to methadone.
What about higher rates in regional areas?
The wastewater report notes higher per capita consumption of some drugs in regional areas. But Population survey data Regional areas show a lower percentage of individuals using illegal drugs.
Wastewater data may overrepresent regional drug use, not because more individuals are using drugs, but because a smaller group is using them an increasing number of continuously.
Regional communities have Less treatment servicesmore Economic stress And tough Social networks which may increase each supply and loss.
Wastewater data cannot even tell which individuals are visitors to an area and who’re residents. For example, festival season may increase in festival areas.
So wastewater data can’t be explained in isolation. It must be read alongside the various other strong data collected by Australia.
A versatile and adaptive market
One of the clearest insights from the wastewater data is just not about consumption, but about how resilient drug markets are.
Despite the large sum of money and energy expended by law enforcement agencies, markets proceed to adapt and in some cases thrive.
With high prices and powerful demand, Australia stays a beautiful market. So when one path is cut off, one other often emerges.
Rather than focusing solely on reducing supply, policy responses must also prioritize harm reduction.
Usage patterns have gotten more concentrated. A small group of individuals appear to be experiencing more severe problems. These people need earlier and more targeted treatment and support to reduce harm.
In the top, it is not nearly how much of the drug is getting used, it’s about what it means to the people using it.
