"Ketamine and phencyclidine have similar modes of action, affecting a range of central neurotransmitters. Ketamine is frequently sold as ‘ecstasy’ in illicit ATS [Amphetamine-Type Stimulants] markets. Street names for ketamine include ‘K’, ‘special K’, ‘kit kat’, ‘tac’, ‘tic’, ‘cat valium’, ‘cat tranquilizer’, ‘vitamin K’, ‘ket’, ‘super K’.38
"Pharmaceutical preparations of ketamine are usually found in liquid form, but powder and capsules are also available. The powder prepared by evaporation of the original solution is often nasally insufflated (‘bumping’), smoked or swallowed."
