Three teenagers were taken to hospital after smoking a cannabis vape in school - said to have been brought in by a pupil in a bid to calm themselves ahead of an exam.
Other pupils at Unity College in Burnley, Lancashire, were treated on site after experiencing a severe reaction.
The device was laced with THC oil, the psychoactive chemical in cannabis, and was allegedly taken to school by a pupil who hoped it would ease nerves ahead of a GCSE test.
But it is claimed the vape was passed round at break and smoked by pupils at the school, which caters for kids as young as 11.
One mum told The Sun: "It’s shocking. The school needs to get a grip."
The parent's daughter is alleged to have a boy foaming at the mouth as paramedics and police arrived at the school, which serves more than 1,100 children aged 11 to 16 and was rated Good by Ofsted after its last inspection in 2018.
Headteacher Jane Richardson said three pupils went to hospital to be assessed on Thursday.
She added that staff worked with police and paramedics “to bring the incident quickly under control”.
It is unclear whether any of the students remain in hospital.
There has been a surge in the UK in young people using vapes, some experimenting by adding THC oil. C
annabis is an illegal class B drug, whereas CBD is extracted from the leaves and flowers of the cannabis plant.
But it does not contain the chemical that makes users high.
A Mirror investigation in 2019 showed there was not then known how effective High Street CBD products were.
Speaking then, Harry Sumnall, Professor in Substance Use at the Public Health Institute at Liverpool John Moores University, said: “The scientific basis for most of the claims is extremely weak and there is also a big difference between treatments tested in laboratories and High Street products.
“And because the UK CBD market is unregulated, consumers cannot always be sure of what they’re buying."
