Drug testing for ketamine

Ketamine was developed in the 1960s to replace phencyclidine (PCP) as an anesthetic agent and is most commonly used in veterinary medicine today.  In addition to rohypnol and GHB, it is also considered a club drug, and may be used in drug-facilitated sexual assault situations.  It is odorless, tasteless and usually swallowed in powder form or injected. Once taken, it is very short-acting and shows effects within minutes. Under federal law, ketamine is classified as a Schedule III drug, meaning it has approved medical use, but still possesses a high potential for abuse.  
According to the National Institute on Drug Abuse, “Ketamine distorts perceptions of sight and sound and produces feelings of detachment from the environment and self.” At low doses, users can experience impaired attention, learning ability and memory. In higher doses, ketamine can cause dreamlike states, hallucinations, delirium, unconsciousness and flashbacks (reoccurrences of certain aspect of the drug experience). Habitual use can cause tolerance and cravings for the drug.
