Devices installed in schools to detect whether children are vaping are being set off up to 22 times a day, data has revealed.
The VapeGuardian sensors send a phone notification to teachers when the smallest hint of vapour is detected. They have been installed in nearly 100 schools across the UK and Ireland.
The shocking figure, released by the device's Southampton-based manufacturer SMF Systems, comes amid the UK's teen vaping crisis, with nearly one in 10 children now using e-cigarettes.
Simon Hassett, the software engineer behind VapeGuardian, which he claims is the first device of its kind made in the UK, said some pupils are so anxious for their next 'fix' they are begging teachers to let them vape at school.
'We are unwittingly creating a new generation of nicotine addicts,' he said.
