This report provides a summary of ecstasy and related drug (ERD) use and market trends in Melbourne, Victoria, from the fifteenth iteration of the Ecstasy and related Drugs Reporting System
(EDRS). These trends have been extrapolated from two data sources: interviews with current regular users of ERD, and a collation of secondary indicator data sources. These two data sources are
compared in order to minimise the biases and weaknesses inherent in each.
