Ketamine is available in powder and liquid form. The powder can be snorted or taken orally. The liquid can be injected intravenously, into a muscle (intramuscularly), or under the skin (subcutaneously).
Phencyclidine (PCP or angel dust) is most often smoked after being sprinkled on plant material, such as parsley, mint leaves, tobacco, or marijuana (some street names are "wet" and "fry"). It can also be snorted or taken orally.

Symptoms
Ketamine and PCP cause giddiness and euphoria, which are often followed by bursts of anxiety. With high doses (overdose), users have a distorted perception of their body, the environment, and time. They feel scattered or as if they are not real (called depersonalization), and they feel detached from their environment (called dissociation).
At even higher doses, hallucinations and paranoid delusions may occur, and the sense of detachment from the world intensifies. Ketamine users often refer to these experiences as a k-hole. People may become combative. Coordination may be lost, and muscles tremble and jerk.
