Ketamine, also known as K or Special K, is a powerful dissociative anesthetic, primarily used for medical and veterinary purposes. When ingested, ketamine can cause users to hallucinate, reduce physical sensations, and even cause temporary limb or speech paralysis. Ketamine is a recreational drug that is mostly sold as a powder or pills, although it is available in an injectable form. When abused, ketamine has potent hallucinogenic properties that lead to highly unpredictable results. Because ketamine affects people very differently, there is no way to know which dosage levels could be unsafe, making it a highly dangerous drug. Ketamine users may develop ulcers in the bladder, have increased blood pressure, experience vomiting, kidney problems, poor memory, and potentially fatal respiratory problems. Users can develop cravings for the drug and can experience distortions of sight and sound. Due to the detached, dreamlike state it creates, ketamine has been used as a “date-rape” drug¹.
