Ketamine 'epidemic' among UK youth raises alarm
The first time Barney Casserly used ketamine at a UK music festival he thought he had found "nirvana". Five years later he died in agony, leaving behind devastated parents and friends.
"I would never, ever have imagined that this would happen to us as a family," said his mother, Deborah Casserly, still grieving for Barney who died in April 2018, aged 21.
