The 2016 NT Trends in Ecstasy and Related Drug Markets report represents the fourteenth year in which data has been collected in the NT on the markets for ecstasy and related drugs (ERD). The Ecstasy and related Drugs Reporting System (EDRS; formerly the Party Drugs Initiative, or PDI) is the most comprehensive and detailed study of ERD markets in the NT.

Using a similar methodology to the Illicit Drug Reporting System (IDRS), the EDRS monitors the price, purity and availability of ‘ecstasy’ (3,4-methylenedioxymethamphetamine; MDMA) and other related drugs such as methamphetamine, cocaine, gamma-hydroxybutyrate (GHB), d-lysergic acid diethylamide (LSD) and ketamine. It also examines trends in the use and harms of these drugs. It utilises data from three sources: (a) surveys with regular ecstasy users (REU) and regular psychostimulant users (RPU); (b) surveys with key experts (KE) who have contact with REU/RPU through the nature of their work; and (c) the analysis of existing data sources that contain information on ecstasy and other drugs.
