Cocaine is a powerful central nervous system stimulant with potent cardiovascular (heart and blood vessel) side effects. Signs of intoxication typically begin with enlarged pupils, a feeling of being "high" (euphoria), agitation, and increased heart rate and blood pressure. With higher doses, sweating, tremors, confusion, hyperactivity, seizures, stroke, cardiac arrhythmias (irregular heart beats), and sudden death can occur. See also: |
