In Queensland in 2008–09, 122 government-funded alcohol and other drug treatment agencies provided 25,523 treatment episodes. The median1 age of persons receiving treatment (for their own drug use and those seeking treatment for someone else’s drug use) was 29 years (31 years for females and 29 years for males).

Cannabis and alcohol were the most common principal drugs of concern at around 36% of treatment episodes each, followed by amphetamines and opioids (8% each, with heroin accounting for half the treatment episodes for opioid use).

The greatest proportion of treatment episodes was for information and education only (40%) followed by counselling (25%) and assessment only (18%).
