Smoking will be banned from all three Queensland University of Technology campuses from the start of the next financial year.

The announcement, which was timed to coincide with Tuesday's World No Tobacco Day, would see QUT follow the Australian Catholic University in Queensland to ban the practice.

A QUT spokeswoman said the university's move to prohibit all types of smoking, including the so-called "vaping" associated with electronic cigarettes, was influenced by its position as health educators and researchers.

"As a leader in health research, education and training, our policies should reflect the same best practice our education and research points to," she said.
