A "junkie" is a colloquial term often used to describe someone who is addicted to drugs, particularly illegal substances. This addiction can lead to a compulsive need to seek out and use these drugs, despite the negative consequences on their health, relationships, and daily life. The term is frequently associated with the use of heroin, cocaine, or other narcotics. Addiction is a complex condition that affects the brain's reward system, making it difficult for individuals to control their substance use. Treatment options for addiction include rehabilitation programs, therapy, and support groups, which aim to help individuals regain control over their lives and reduce their dependence on drugs.
