drug addiction and dependence

Drug addiction refers to a chronic brain disorder characterized by compulsive drug-seeking and drug use, despite negative consequences. It involves the strong desire or craving for a drug, with an inability to control or stop its use. Drug dependence, on the other hand, refers specifically to the physical and psychological dependence on a drug, where the body has adapted to the drug's presence and requires it to function normally. Both addiction and dependence can have severe impacts on a person's health, relationships, and overall well-being.
