An inquiry by the Queensland Productivity Commission found that the number of drug users being locked up in Queensland prisons is pushing the system to breaking point, with more people being sent to prison now than any time in the past 120 years. 

The inquiry was set up by the Palaszczuk government to work out what was causing the surge of people in the state’s prisons.

The commission also found that locking up drug users was often a waste of time and money and recommended that some drug offenders be kept out of the prison system.
