MDMA-related fatal poisonings in Australia rose to 2019 then fell through 2023

A national coronial series of 217 MDMA-related fatal poisonings in Australia found the population rate rising sharply to 2019 (annual percentage change 61.5) then falling to 2023 (-26.7), with 82.5% of deaths attributed to multiple drug toxicity and 78.8% occurring in private settings.

Researchers retrieved all MDMA-related fatal poisonings recorded in Australia's National Coronial Information System for 2016-2025, yielding 217 cases, and estimated population rates for the years with high case-closure rates. The rate rose over 2016-2019 (annual percentage change 61.5) and fell over 2019-2023 (-26.7); mean age was 33.5 years, 78.3% were male, and death was attributed to multiple drug toxicity in 82.5% of cases, with other psychoactive drugs detected in 91.7%. Case characteristics, including MDMA blood concentrations and cardiomegaly, did not differ significantly across pre-COVID, COVID and post-COVID periods.

Why it is interesting: Places MDMA deaths in a national mortality series and shows they are overwhelmingly polysubstance and private, not festival, events.
