DESCRIPTION #
Many users report feelings of dissociation, perceptual alterations and loss of coordination after using the drug. Intense hallucinations and delusions as well as a loss of physical control and coordination are also commonly experienced. PCP has been known to induce seizures, coma and even death, especially at high doses, and there is some evidence to indicate that, whilst not physically addictive, it can lead to psychological dependency and drug-seeking behaviour.

Long-term use has been known to lead to schizophrenia-like psychotic episodes, severe lasting memory loss, disorganised thinking, depression, weight loss, liver abnormalities and rhabomyolysis (skeletal muscle breakdown).
