The NSW EDRS sample comprises a sentinel sample of people who regularly use ecstasy and other illicit stimulants recruited via social media, advertisement on websites and via word-of-mouth in Sydney, NSW. The results are not representative of all people who use illicit drugs, nor of use in the general population. Data were collected in 2020 from May-June, subsequent to COVID-19 restrictions on travel and gatherings in Australia. Interviews were also delivered via phone/videoconference rather than face-to-face. This should be factored into all comparisons of data from the 2020 sample relative to previous years.
