ketamine was one of the key drugs identified in the study
Drug consumption in England rises sharply during heatwaves, bank holiday weekends and major events like football matches and the Eurovision Song Contest, according to a large-scale wastewater study.Researchers analysed over 1,700 wastewater samples from 15 treatment plants across England in 2022, revealing clear weekly and seasonal trends. Cocaine was the most commonly detected drug, followed by heroin, ketamine, amphetamine and MDMA.While weekend spikes were prominent, cocaine use remained consistently high throughout the week.
Event-driven surges
Drug use increased significantly during major events such as World Cup matches, summer heatwaves and national celebrations like the late Queen’s platinum jubilee.The Eurovision Song Contest stood out as one of the most drug-fuelled nights, with notable rises in cocaine, ketamine, MDMA and methamphetamine use.
Ketamine a growing concern
Unlike other substances, ketamine use remained steady across weekdays and weekends, indicating routine consumption.Researchers found levels at several sites higher than those reported anywhere else in Europe, raising concerns about its growing popularity and risks.
Heatwaves increase health risks
Experts warn that taking drugs during hot weather increases the risk of dehydration, overheating and overdose. The study also highlighted the dangers of mixing substances, especially cocaine with alcohol, which creates harmful compounds in the body.
Helping emergency services prepare
The findings can help authorities anticipate periods of increased drug use and related emergencies.By identifying predictable spikes linked to events, emergency services can better prepare and public health messaging can be timed more effectively.
Crackdowns show impact
The study also showed how large drug seizures can disrupt consumption. A major cocaine seizure in Southampton in March 2022 led to a noticeable drop in use across several cities for nearly a month.Officials warn that rising ketamine use, particularly among those aged 16 to 24, is a growing concern. Often perceived as a “safe party drug”, it can cause serious long-term physical and psychological harm.
