Thirteen teenagers were treated by paramedics at La Sainte Union Catholic School in Highgate, north London, on Monday morning before being taken to hospital.

We understand the sweets contained THC. We await tests to establish the quantity of THC in each sweet. While we await a full update from hospital, nobody is seriously unwell. There has been no arrest; enquiries continue.— Camden Police (@MPSCamden) October 5, 2020
Investigations are under way to establish the quantity of THC in each sweet, the Metropolitan Police’s Camden branch said.
None of the teenagers are “seriously unwell”, the force added.
