Between 1999 and 2023, 4719 samples submitted as MDMA to the DrugsData drug checking service were analyzed. While 75% of users expected their sample to contain only MDMA, only 48% actually contained MDMA alone. The proportion of MDMA-only samples declined sharply from 57.4% in 1999 to 15.2% in 2009, then recovered to 56.0% by 2017, and rose more moderately to 74.1% by 2023. Across the 25-year period, 199 unique adulterants were detected. Trends in adulterant prevalence matched those seen in law enforcement seizure data. Although more than half of MDMA samples were misrepresented in some way, MDMA quality has stabilized at relatively high levels in recent years.
