Ketamine Detection Rates in Drug Overdose Deaths on the Rise in the U.S.
A recent study reveals a notable increase in ketamine detection rates related to drug overdose deaths in the United States, rising from 0.3% in 2019 to 0.5% in 2023. This upward trend highlights the growing presence of ketamine, a substance commonly associated with treatment-resistant depression, in the context of increasing polysubstance use and overdose fatalities.
Overview of the Study Findings
The study, published on November 7 in the Morbidity and Mortality Weekly Report, was spearheaded by Dr. Alana M. Vivolo-Kantor from the Division of Overdose Prevention at the Centers for Disease Control and Prevention (CDC). Researchers examined data from the State Unintentional Drug Overdose Reporting System, analyzing 228,668 overdose deaths across 45 jurisdictions in the U.S. by using death certificates, coroner reports, and toxicology results to assess the involvement of ketamine.
Key statistics from the findings include:
- Detection and Involvement: Ketamine was detected in 912 cases (0.4%) and involved in 440 deaths (0.2%). Remarkably, it was the sole substance involved in only 24 deaths (0.01%).
- Polysubstance Trends: Of those who tested positive for ketamine, 59% also had illegally manufactured fentanyls in their systems, 29% had methamphetamine, and 27% consumed cocaine.
- Demographic Insights: The majority of deceased individuals were men (71%) and non-Hispanic White persons (74%). The age group most affected was 25-34 years old, constituting 35% of the ketamine-involved cases.
The trend analysis indicates that overdose deaths in which ketamine was detected grew from 47 (0.3%) in the latter half of 2019 to 107 (0.5%) in early 2023.
The Growing Concern of Polysubstance Use
“As polysubstance use and the use of ketamine for treatment-resistant depression and in compounded formulations increase, continued monitoring is needed,” Dr. Vivolo-Kantor advised. The study underscores the vital importance of understanding the potential interactions between ketamine and other drugs, as well as the circumstances under which these overdoses occur.
The rise in ketamine detection adds another layer to the ongoing narrative of America’s drug crisis, chiefly driven by opioids. Illegally manufactured fentanyls remain predominant in the landscape of fatal overdoses, often complicating the clinical picture when combined with other substances.
Methodological Considerations
The study’s methodological framework involved trend analyses across 28 jurisdictions with comprehensive toxicology results for at least 75% of relevant deaths. While the findings provide crucial insights, researchers caution that the results may not be universally applicable due to the study’s focus on select jurisdictions. Additionally, discrepancies in postmortem toxicology testing protocols and inconsistencies in the inclusion of ketamine within testing panels may mean the actual detection rates could be higher than reported.

A Call for Increased Awareness and Monitoring
The data presented in this study suggests an urgent need for ongoing monitoring of ketamine’s involvement in overdose deaths. As attitudes toward ketamine therapy for mental health treatments shift, stakeholders at all levels—healthcare providers, policymakers, and public health officials—must remain vigilant.
Continuous surveillance will be essential in grasping the complexities surrounding current drug use trends and mitigating risk to the population. As society grapples with the repercussions of substance misuse, it is crucial to foster conversations about drug safety and the need for precise diagnostics.
