Ketamine – Ketamine hydrochloride is an animal tranquilizer used by veterinarians. When used in humans it often produces hallucinations that include visual distortions, a lost sense of time, and identity. A Ketamine high can last anywhere from a half an hour to two hours. Even when a person is not feeling the effect of the drug, Ketamine can still affect the body for up to 24 hours. One form of Ketamine comes in a powder and is usually snorted, but some users sprinkle it on tobacco or marijuana and it is then smoked. The second form of Ketamine comes in a liquid form and the third form is a pill. Ketamine is often used as a date rape drug and it is mixed into victim’s drinks. Because this drug is odorless and tasteless, a person can consume it without knowing.
