Medical professionals operating the United Kingdom's first and only specialized NHS clinic for ketamine-induced bladder damage have issued a warning regarding the age of their patients. According to clinical reports, the facility is now treating individuals as young as 13 for severe urological complications linked to the recreational use of the drug.

Ketamine, a dissociative anesthetic, is known to cause significant damage to the urinary tract when used chronically. The condition, often referred to as 'ketamine bladder,' involves inflammation and scarring of the bladder wall, which can lead to reduced bladder capacity and chronic pain. Patients treated at the clinic have described the physical sensation of passing damaged tissue as akin to 'peeing a jellyfish,' a phrase that underscores the severity of the internal tissue degradation caused by the substance.

While the BBC report focuses on the clinical reality of these cases, it does not detail the broader socioeconomic factors driving youth drug use or the specific frequency of consumption required to trigger such advanced damage in minors. The report serves as a primary medical account of a growing public health concern, highlighting the shift toward younger demographics seeking treatment for a condition previously more commonly associated with adult users. As the NHS clinic remains the sole facility of its kind in the country, it serves as the primary data point for understanding the current scale of this issue among adolescents.
