The Illicit Drug Reporting System (IDRS) is an ongoing illicit drug monitoring system which has been conducted in all states and territories of Australia since 2000, and forms part of Drug Trends.

Naloxone is an opioid antagonist that is a safe and effective agent for reversing the effects of opioids, such as heroin and morphine. Since 2012, take-home programs have been established to make naloxone more widely available so that it can be administered by people other than medical professionals.

Using IDRS data from 2013 to 2018, this briefing note aims to examine knowledge of these take-home programs and naloxone more broadly, among a sample of PWID recruited as part of the IDRS in Victoria, Australia.
