Smoking is set to be banned in all Queensland prisons next year.
The state government plans to make tobacco a prohibited item in all correctional facilities, which will effectively ban all inmates and staff from smoking from May 5.
The policy was released in a prisoner information handbook that was uploaded to the Queensland Corrective Services website on Friday night.
Attorney-General Jarrod Bleijie has confirmed the ban and says it will benefit both prisoners and staff.
"The harmful effects of smoking have been known for a long time and our hard-working corrections staff deserve to be able to work in a completely smoke-free environment," Attorney-General Jarrod Bleijie told the Courier-Mail.
The Cancer Council Queensland said the policy was in line with the Northern Territory's ban, with other states considering similar action.
However, spokeswoman Katie Clift said there had to be adequate support for prisoners forced to quit smoking.
"It is vital that smoking cessation programs and interventions are freely available to prisoners, including access to the Quitline and nicotine replacement therapy," she said in a statement.
