Queensland schools have been forced to lock up toilets to crack down on students vaping in the bathroom during classes. Aquinas College on the Gold Coast have closed their toilets and students will now undergo a check-in procedure to get their teacher's permission to use the facilities during a lesson. On Wednesday a letter was sent to parents advising of a 'procedural change' in response to 'behavioural and students welfare concerns,' the Gold Coast Bulletin reported.
