Drug effect
Ketamine is a dissociative anaesthetic with analgesic (painkilling) properties and effects vary according to dosage and method of administration. Although an anaesthetic agent, it is not a respiratory depressant, and it can produce altered states of consciousness. It is used in hospitals as a general anaesthetic and is normally given by either intravenous or intramuscular injection. If injected or snorted, effects will come on quickly and may be very intense. The user can become so divorced from reality that the surrounding environment is perceived completely differently. Users may feel numb, uncoordinated and nauseous for a few hours after the most intense effects wear off. When eaten, the process of dissociation is slowed down and users may feel numb and uncoordinated although conscious of their surroundings. Ketamine is structurally related to phencyclidine (PCP).
