Ketamine, categorized as a “dissociative anesthetic,”1 is used in powdered or liquid form as an anesthetic, usually on animals. It can be injected, consumed in drinks, snorted, or added to joints or cigarettes. Ketamine was placed on the list of controlled substances in the US in 1999.
Short- and long-term effects include increased heart rate and blood pressure, nausea, vomiting, numbness, depression, amnesia, hallucinations and potentially fatal respiratory problems. Ketamine users can also develop cravings for the drug. At high doses, users experience an effect referred to as “K-Hole,” an “out of body” or “near-death” experience.
Due to the detached, dreamlike state it creates, where the user finds it difficult to move, ketamine has been used as a “date-rape” drug.
