Recreational ketamine use and its impact on health

Ketamine, also known as 2-(2-chlorophenyl)-2-(methylamino)-cyclohexanone, is a dissociative anesthetic that has gained popularity as a recreational substance among young people, especially in nightclubs and at parties. It acts as a noncompetitive NMDA receptor antagonist, inducing a dissociative state that manifests as catalepsy, unconsciousness and amnesia. Recreational use of ketamine and the number of illicit seizures of ketamine have increased in recent years, prompting a review of current evidence on its toxicity. Recreational ketamine use is associated with a number of toxic effects, both acute and chronic. Predominant among the acute effects are psychotic symptoms, hallucinations and aggression, which can lead to serious injuries. Chronic ketamine use leads to intractable urological problems and neuropsychiatric problems, Long-term effects also include gastrointestinal problems such as abdominal pain and liver function abnormalities. This review summarizes current evidences on the acute and chronic ketamine toxicity associated with its recreational use.
