Regular injecting drug user population—reported recent use (%) and median days of use

2008 to 2017

Source: Illicit Drug Reporting System, National Drug & Alcohol Research Centre.

A national study of regular injecting drug users indicates that:

  • Crystal remains the predominant form of methylamphetamine reportedly used within this user population.
  • Although the proportion of respondents reporting recent cannabis use has remained relatively stable since 2014, the frequency of use has increased during the same period.
  • Within this user population the reported median days of heroin use in the six months preceding interview decreased, from 90 days in 2015 to 75 days in 2016. This further decreased to 72 days in 2017.
  • Although the reported median days of cocaine use in the six months preceding interview remained unchanged at three days in 2017, the proportion of respondents reporting the recent use of cocaine increased, from 11.0 per cent in 2016 to 13.0 in 2017.
