In Queensland in 2009–10, 118 government-funded alcohol and other drug treatment agencies provided 23,090 treatment episodes. The median1 age of persons receiving treatment (for their own drug use and those seeking assistance for someone else’s drug use) was 29 (females 31; males 29). Alcohol and cannabis were the most common principal drugs of concern at 38% and 36% of treatment episodes respectively, followed by opioids (8%), with heroin accounting for half of this (4%). The greatest proportion of treatment episodes was for information and education only (42%) followed by counselling (28%) and assessment only (17%).
