The Answers Sent Them Spiraling.”, in The New York Times, →ISSNUrology departments across the UK could be close to breaking point after ketamine-related hospital admissions have "skyrocketed" in recent years, experts have warned. The class-B dissociative drug used for pain relief and sedation is increasingly used recreationally in the UK. […] a consultant urological surgeon in Sheffield, said admissions tied to ketamine abuse had "skyrocketed" in the past few years, and that not enough users understood the effect that consistently taking the drug would have on their bodies. "Ketamine is a unique drug because it seems like there are no side-effects, but it's more complicated than that," he said. "It slowly impacts the bladder and the liver, and then the urinary tract. It takes a couple of years to begin to notice these effects, but once you start noticing them they're pretty irreversible."
