A coroner has issued a warning about the dangers of ketamine after ruling that an 18-year-old boxer died from a cocktail of hard drugs including ketamine, cocaine and Xanax following a night out with workmates.

Senior coroner Professor Fiona Wilcox ruled that 18-year-old former England schoolboys boxing hopeful Calum Naylor, from Islington, died of multiple drug toxicity — a case of drug-related misadventure — after ingesting ketamine, cocaine, ecstasy and Xanax at a Notting Hill house party on December 7, 2024, and issued a warning about young people taking ketamine 'with abandon'.
