Prevalence of Injection Drug Use

"It has been estimated that a very low proportion of the Australian general population aged 14 years and over have ever injected or recently injected drugs. In 2010, 1.8% of the population had injected a drug in their lifetime, with 0.4% having injected a drug in the past year. More than one-quarter (27.1%) of recent users injected daily and the majority obtained their needles and syringes from a chemist (64.5%). Males were more likely to have recently injected drugs in the past year than females (0.6% versus 0.3%). Those in the 20-29 and 30-39 year age groups had a higher proportion of past-year injecting drug use (0.9% for each) than those in other age groups (Australian Institute of Health and Welfare, 2011).
"Another recent prevalence estimate of injecting in Australia in 15-64 year olds is 1.09% (range = 0.65%-1.50%) which equates to approximately 149,591 persons (range = 89,253-204,564) (Mathers, Degenhardt, Phillips et al., 2008)."
