Cocaine addiction works by altering the brain’s reward system, leading to compulsive drug seeking behavior despite negative consequences. Cocaine is a highly addictive stimulant drug that increases the levels of dopamine in the brain, producing feelings of pleasure and euphoria. Over time, repeated use of cocaine can cause changes in the brain that lead to addiction. As a person continues to use cocaine, their tolerance to the drug builds, leading to increased use to achieve the same effects. Additionally, withdrawal symptoms can be unpleasant and intense, leading users to continue using to avoid these symptoms. Psychological dependence on cocaine can also develop, leading to cravings and drug seeking behavior. In addition to changes in the brain, cocaine addiction can also lead to a range of negative physical and psychological effects on the body, including heart problems, respiratory issues, and mental health problems.
