Smoking is emerging as a smouldering issue for the University of Queensland, with the student union continuing to press for a repeal over concerns about the safety.

The ban, which came into effect on July 1, prohibited all forms of smoking on University of Queensland campuses, including the use of electronic cigarettes otherwise known as "vaping".

UQ Union science councillor Nerissa Aitken said the union's Student Council passed a motion in March this year based on concerns over the safety of students.

Ms Aitken cited the size of the St Lucia campus, arguing that the campus was dangerous even for non-smokers.
