Ketamine has emerged as a defining drug for a generation of young Brits. A report from November 2020 revealed that 1-in-30 young people had used ketamine in the past year — the highest rate ever recorded and significantly higher than in other European countries. Current data ranks ketamine as the fourth most commonly used drug among young people, following cannabis, ecstasy, and cocaine. There’s a striking contradiction at the core of what's been dubbed "Generation K": ketamine is both dismissed as a bizarre, almost comical horse tranquiliser and feared for its very real, dangerous effects—including the risk of severe bladder damage and addiction. As its popularity has surged, so too have cases of ketamine-related health issues, including users developing conditions that cause them to urinate blood. In this report, Matt Shea dives into the world of Generation K to explore how a party drug can spiral into something far more harmful.
