Rising Ketamine and Crack Cocaine Use in Switzerland

Overview of Substance Use Trends
Recent analyses of wastewater conducted by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) reveal a significant increase in the consumption of ketamine and crack cocaine in Switzerland during the first half of 2025. The findings indicate that while the use of methamphetamine and cannabis has slightly decreased, the levels of ketamine and crack cocaine have risen notably, particularly in urban areas like Zurich and Chur.
Key Findings from Wastewater Analysis
The wastewater analysis, which aims to provide insights into drug consumption patterns where sales data may be unreliable, shows that ketamine levels in Zurich are significantly higher than in other surveyed locations across Switzerland. This increase is particularly pronounced during weekends, suggesting a correlation with recreational use in nightlife settings. Ketamine, an anesthetic commonly known as "K" or "Special K" in club culture, has seen a marked rise in usage, although the data does not differentiate between medical and recreational consumption.
Similarly, the analysis indicates a rise in crack cocaine consumption, measured through the presence of anhydroecgonine methyl ester (AEME), a degradation product of crack. The levels of AEME in wastewater have also increased significantly in both Zurich and Chur, with weekend consumption patterns mirroring those observed for ketamine.
Decrease in Other Substances
In contrast to the rising trends of ketamine and crack cocaine, the analysis shows a slight decline in the use of methamphetamine and cannabis. Methamphetamine levels have decreased since monitoring began in 2021, while the levels of THC-COOH, a metabolite of cannabis, were lower in the first two quarters of 2025 compared to previous years.
Implications of Rising Drug Use
The increase in ketamine and crack cocaine use raises concerns about public health and safety, particularly in urban centers where nightlife is prevalent. The data suggests a need for enhanced prevention and intervention strategies to address the rising trends in recreational drug use. Experts emphasize the importance of understanding the motivations behind these consumption patterns to effectively tackle addiction and its associated risks.
Official Statements & Responses
Eawag researchers have highlighted the importance of wastewater analysis as a reliable method for tracking drug consumption trends. They assert that "wastewater doesn’t lie," underscoring the value of this approach in public health monitoring. The Swiss government and health organizations are expected to respond to these findings with potential policy adjustments aimed at addressing the increasing drug use.
Criticism & Opposition
While the data provides valuable insights, there are concerns regarding the implications of rising drug use on community health and safety. Critics argue that without adequate preventive measures and public awareness campaigns, the situation may worsen, leading to increased addiction rates and associated social issues.
Conflicting Reports & Gaps
There is currently no detailed breakdown of the specific sources of ketamine and crack cocaine use, leaving a gap in understanding the full scope of the issue. Additionally, the distinction between medical and recreational use of ketamine remains unclear, complicating the response strategies that may be needed.
