Cocaine is a very potent stimulant of the central nervous system. It blocks the reabsorption of the chemical dopamine by neurons which causes increased pleasure signaling as a result of continuous activation of nerve cells in the brain.
Forms
Cocaine can be snorted or injected (when dissolved in water) when it is in its salt form. If cocaine has not been turned into a salt, it is called crack and can be smoked.
Euphoric Effects
Cocaine use can cause euphoria and decreased fatigue, mental alertness and increased stimulation.
Physical Effects
Cocaine use can cause high blood pressure, dilated pupils, elevated heart rate and temperature, and constricted blood vessels.
Psychological Effects
Some cocaine users report that they have feelings of anxiety, restlessness and irritability.
Addiction
Cocaine users may develop tolerance to the drug, which means that higher doses of the drug are necessary to achieve its effects. In addition, people can become physically dependent on cocaine, resulting in withdrawal when cocaine is not present in the body.
