Cocaine is a powerful central nervous system stimulant. Signs of intoxication typically begin with enlarged pupils, euphoria, agitation, and increased heart rate and blood pressure. With higher doses, symptoms can progress to sweating, tremors, confusion, hyperactivity, seizures, stroke, cardiac arrhythmias, and sudden death.

At high doses of PCP, there is a drop in blood pressure, pulse rate, and respiration. This may be accompanied by nausea, vomiting, blurred vision, vertical nystagmus, drooling, loss of balance, and dizziness. High doses of PCP can also cause seizures, coma, and death (though death more often results from accidental injury or suicide during PCP intoxication). Psychological effects at high doses include illusions and hallucinations. PCP can cause effects that mimic the full range of symptoms of schizophrenia, such as delusions, paranoia, disordered thinking, a sensation of distance from one's environment, and catatonia. Speech is often sparse and garbled.

The hallucinogenic property and the tendency to induce vertical,horizontal or rotatory nystagmus in the case of PCP,and the sympathatomimetic properties of cocaine set the two apart.

" While the predominant effect is sympathomimetic, a number of other effects may be observed to varying degrees in individuals who are intoxicated with PCP." www.emedicine.com
