Ketamine was one of the main drugs identified in the study
Drug consumption in England rises sharply during heatwaves, weekends and major events such as football matches and the Eurovision Song Contest, according to a large-scale study into wastewater.The researchers analyzed more than 1,700 wastewater samples from 15 treatment plants across England in 2022, revealing clear weekly and seasonal trends. Cocaine was the most common drug, followed by heroin, ketamine, amphetamine, and ecstasy.While weekend spikes were notable, cocaine use remained consistently high throughout the week.
Event-driven mutations
Drug use has increased significantly during major events such as World Cup matches, summer heatwaves and national celebrations such as the late Queen’s platinum jubilee.The Eurovision Song Contest has emerged as one of the most drug-filled nights, with a notable rise in cocaine, ketamine, ecstasy and methamphetamine use.
Ketamine is a growing concern
In contrast to other substances, ketamine use remained constant across weekdays and weekends, suggesting routine consumption.Researchers found levels in several locations higher than those reported elsewhere in Europe, raising concerns about its growing popularity and risks.
Heat waves increase health risks
Experts warn that taking medications during hot weather increases the risk of dehydration, high temperature, and overdose. The study also highlighted the dangers of mixing substances, especially cocaine, with alcohol, which leads to the formation of harmful compounds in the body.
Help emergency services prepare
The results could help authorities anticipate periods of increased drug use and related emergencies.By identifying expected surges associated with events, emergency services can be better prepared and public health messages can be timed more effectively.
The crackdowns are showing their 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 decline in use in several towns for almost a month.Officials warn that the rise in ketamine use, especially among those ages 16 to 24, is a growing concern. It is often viewed as a “safe party drug” and can cause serious long-term physical and psychological harm.
