CCocaine dependence is a form of psychological dependence that develops from regular cocaine use and produces a withdrawal state with emotional-motivational deficits after stopping cocaine use.
Cocaine is a potent stimulant most frequently used as a recreational drug. Cocaine is a highly addictive drug due to its effect on the reward pathways in the brain. Cocaine acts by increasing the number of feel-good chemicals in the brain such as dopamine and serotonin.
Cocaine is commonly snorted, inhaled as smoke, or dissolved and injected into a vein. Effects usually begin within seconds to minutes of use and last between five and ninety minutes.
Between 1 to 3% percent of people in the developed world have used cocaine at some point in their lives.
