Ketamine use in the UK has surged dramatically, with consumption nearly doubling in just one year, according to new data from the Home Office Wastewater Analysis Programme (WWAP).
The government-backed study, which analyses wastewater from treatment plants across England and Scotland to estimate the use of illicit substances, found that ketamine levels rose from 545mg to 1,008mg per 1,000 people per day between early 2023 and early 2024 – an increase of over 85%.
Wastewater analysis is increasingly used as a reliable, population-level tool to monitor substance use trends. By detecting traces of drugs in sewage, researchers can estimate how much of a given substance is being consumed in a specific area, helping public health bodies and law enforcement agencies respond more effectively.
What is ketamine?
The results of the study indicate a concerning shift in recreational drug use, particularly among young adults.
Ketamine is a powerful dissociative anaesthetic, originally developed for use in medical and veterinary settings. Although it is still used today in hospitals and clinics – primarily for pain management and sedation during surgery – the drug has gained popularity as a recreational drug due to its hallucinogenic and euphoric effects.
When misused, ketamine can induce a range of psychological and physical effects, including:
- Distorted perceptions of time and space
- Hallucinations and out-of-body experiences
- Sedation and disconnection from reality (often referred to as entering a “K-hole”)
- Slurred speech and impaired motor coordination
- Confusion, anxiety, and agitation
What the data shows
The findings of the wastewater analysis suggest that ketamine use is becoming increasingly entrenched in the UK’s recreational drug scene.
As well as usage almost doubling within one year, ketamine showed the largest percentage increase of any drug monitored in the study, outpacing other commonly misused substances including cocaine, MDMA and amphetamine.
It was also detected in all monitored sites, suggesting widespread use across different regions and demographics, while other drugs such as heroin and methamphetamine showed a decline in use over the same period.
These findings echo wider concerns by medical professionals and drug charities who have reported an increase in ketamine-related hospital admissions and mental health issues in recent years.
Key drivers that are thought to have contributed to increased ketamine use include:
- Perceived safety – Ketamine is often wrongly viewed as a ‘safer’ alternative to other illicit drugs because of its use in medical settings.
- Social and recreational use – The drug has become popular in club and festival environments among users seeking heightened sensory experiences.
- Accessibility and affordability – Ketamine is often cheaper and more readily available than other recreational drugs, commonly distributed online and via social media sites.
- Lack of awareness – Many people are unaware of the long-term health risks associated with ketamine, including serious bladder conditions and cognitive impairment.
Health risks of ketamine misuse
While some users may seek out ketamine for its mind-altering effects, the drug carries significant health risks when taken regularly or in high doses, including:
- Bladder and urinary tract damage – Chronic ketamine use is strongly linked to interstitial cystitis or bladder pain syndrome, a painful condition that can lead to long-term bladder damage.
- Cognitive impairment – Long-term use can affect memory, attention and decision-making ability.
- Addiction – While not traditionally associated with dependency, users can develop a strong psychological dependence on ketamine over time.
- Accidental injury – The dissociative effects of ketamine increase the risk of accidents and injuries, particularly when the drug is used in combination with other depressants like alcohol.
