Research: Wastewater analysis: estimating drug consumption, 2021 to 2026
This report presents the latest findings from the Wastewater Analysis for Narcotics Detection (WAND) programme. It updates the 2021 to 2026 trend analysis for 6 key drugs: cocaine, ketamine, amphetamine, methamphetamine, MDMA, and heroin.
The trend analysis is based on samples from 16 English sites monitored consistently since 2021. Cocaine remained the most consumed of the 6 key drugs, while estimated ketamine consumption decreased by 11% between 2025 and 2026 after several years of sustained growth.
