What does wastewater tell us about drug consumption

The wastewater of New Zealand is tested every month for drugs of abuse. This is a nationwide program that started in November 2018 and now covers up to 75% of the population. The purpose of the testing is to provide an indication of drug consumption across the country. In the most recent report, covering October to December 2021, methamphetamine, MDMA and cocaine were detected in significant quantities.

Some key findings in this quarterly report are:

Methamphetamine

• The average national weekly methamphetamine use was 32% higher than the average quantity detected over the previous 4 quarters.

• Per capita methamphetamine use was highest in Northland district.

• Waikato, Tāmaki Makaurau and Central districts have all shown steady increases in methamphetamine consumption each quarter in 2021.

MDMA (methylenedioxymethamphetamine)

• There was a small increase in MDMA consumption in most districts.

• Canterbury district, followed by Southern district, consumed the most in this quarter.

Cocaine

• Cocaine use was low compared to previous quarters.

• Tāmaki Makaurau continued to consume the most cocaine per capita.
