High levels of methamphetamine have been found in Whangarei's wastewater treatment plant.
Methamphetamine, MDMA/Ecstasy and cocaine have been found in the wastewater since monthly testing began in August.
Until now, reliable data about illegal drug usehas been difficult to obtain. Wastewater testing provides a cost-effective, timely, non-intrusive and accurate measure of illegal drug use.
The testing and the Rataora Trial are programmes within Te Ara Oranga, providing evidence-based data about illegal drug use in Whangarei.
Police and health officials are working together in Northland to reduce methamphetamine demand by improving treatment services and increasing responsiveness.
