UK Children as Young as 13 Suffering Severe Bladder Injuries from Ketamine Abuse

Rapid Rise in Pediatric Ketamine Referrals at Alder Hey Hospital

Medical professionals at Alder Hey saw just one young patient with ketamine-related complications in 2023. That figure rose to nine patients in 2024 before triggering a rapid escalation in 2025 that forced the opening of a dedicated clinic in May 2025. The facility currently receives about one referral every week from general practitioners and emergency departments across Cheshire, Merseyside, and surrounding regions. Of the first 60 patients evaluated at the clinic, 43 were girls.

Isba, involved in the clinic’s operations, notes that children frequently report experimenting with multiple substances. While alcohol and cannabis remain more widely used among youth, ketamine has climbed into third place. Pediatric patients treated at the clinic frequently report concurrent alcohol consumption, vaping, and use of other drugs.

Medical Complications of Ketamine Bladder Syndrome

Chronic ketamine consumption causes severe pathology throughout the urinary tract, including the bladder, ureters, and kidneys. According to the British Association of Urological Surgeons, approximately three out of every ten frequent users develop bladder issues. Common symptoms include an urgent and frequent need to urinate, and hematuria, which manifests as blood-stained urine.

In addition to urinary tract damage, heavy users frequently suffer from abdominal pain and muscle spasms, commonly referred to by users as “K cramps.” While bladder damage can sometimes reverse if the patient stops taking the drug entirely, some cases are so serious that surgeons must perform surgical repair or total surgical removal of the bladder.

Regulatory Debates and Treatment Access Gaps

There have been calls to reclassify ketamine from a Class B substance to a Class A drug alongside cocaine and heroin. However, the Advisory Council on the Misuse of Drugs recommended to the government that the substance remain categorized under Class B alongside amphetamines and cannabis.

Isba highlights significant structural gaps in adolescent addiction services across the UK. Children under 16 who are dependent on substances face disadvantages because specialized inpatient detoxification facilities are not available for them in the UK, whereas those aged 18 would be offered an inpatient detox stay. This leaves young patients who are ready to stop without appropriate residential support systems.
