Rising Prevalence of Ketamine and Psychoactive Drugs on College Campuses

Recent legal proceedings and medical observations have brought renewed attention to the presence of psychoactive substances on university campuses across the United States. Following a civil lawsuit filed in September 2026 by a former Cornell student alleging that she was pressured into taking ketamine before an assault, experts have highlighted a broader trend concerning the availability and misuse of designer drugs in higher education settings.

The Growing Supply and Availability of Ketamine

Originally synthesized in 1962 and approved by the U.S. Food and Drug Administration in 1970 as a general anesthetic for humans and animals, ketamine has a long history in clinical and veterinary medicine. Over the decades, it also found a place in recreational settings, appearing in club and rave scenes during the 1980s and 1990s under street names such as Special K and Vitamin K. In 2019, the FDA approved a nasal spray derivative called esketamine for treatment-resistant depression, and clinicians increasingly prescribe ketamine off-label for psychiatric conditions including post-traumatic stress disorder. According to nationwide poison control center analyses, U.S. poisoning cases involving ketamine doubled between 2019 and 2023, driven partly by expanded medical access alongside novel analogs synthesized in clandestine laboratories.

Physiological Effects and Detection Challenges

Medical toxicologists note that ketamine acts as a dissociative agent, altering consciousness, sensory perception, and a person’s connection to their surroundings. Depending on the route of administration, effects can begin within minutes and typically wear off within an hour, though impaired judgment, coordination, and dulled senses can persist for hours. Higher doses can lead to delirium, amnesia, elevated blood pressure, breathing difficulties, and coma. Because the substance can be found as an odorless liquid or powder, it can be easily added to food or drinks. Furthermore, standard hospital urine drug screens often fail to detect ketamine and its evolving analogs. Rapid metabolization by the body and delays in seeking medical evaluation further complicate detection in clinical and forensic contexts.

Implications for Campus Safety and Reporting

Public health professionals emphasize that psychoactive drugs complicate issues of consent and safety in university environments. While research indicates that mind-altering substances are frequently used voluntarily by individuals, documented reports also involve individuals being covertly drugged. One cited study estimated that a small percentage of sexual assault victims experienced covert drugging, though experts suggest such incidents are significantly underreported due to detection limitations, trauma, social stigma, and concerns regarding institutional support. Public health advocates underscore the need for enhanced education, prevention initiatives, and advanced screening methodologies to address the evolving landscape of psychoactive substances in student populations.

• Ketamine was approved as an anesthetic in 1970 and has seen increased medical and recreational use.
• Poison control center data showed a doubling of ketamine-related poisoning cases between 2019 and 2023.
• Standard urine drug screens frequently fail to detect ketamine and emerging psychoactive analogs.
