Physical Effects PCP in small doses causes sedation, numbness of the extremities, loss of muscle coordination and dizziness. Users tend to have a blank stare or experience involuntary rapid eye movements accompanied by blurred or double vision. Users may also experience flushing, profuse sweating, nausea, vomiting and an increase in heart rate, blood pressure and breathing. In larger doses, PCP's painkilling and anesthetic qualities are prevalent. There is a significant drop in blood pressure, breathing and heart rate.
Users appear drunk because they are uncoordinated.
They may experience shivering, increased salivation, watery eyes, loss of balance, dizziness and muscular rigidity, and they may exhibit repetitive movements such as rocking back and forth. Their speech is often confused and their vision may be distorted. For the next few hours, thinking, remembering, and making decisions can be very difficult. With high doses, PCP users become extremely agitated. Seizures or coma may follow.
