What is Addiction? Addiction is a chronic, relapsing brain disease that is characterized by compulsive substance use or behavior.
What Does Addiction Mean? Addiction is the condition of being dependent on a substance, multiple substances, a thing, or a behavior.
How Does Addiction Affect the Brain? Addiction changes the brain in fundamental ways, causing impaired control over impulses and weakened ability to make reasoned decisions.
What Causes Drug Addiction? The causes of drug addiction, better known now as substance use disorder (SUD), are still not completely understood and need more research. Alcohol and drugs artificially trigger the brain’s reward centers, which, for some individuals, can lead to compulsive substance use and substance-seeking behavior regardless of negative consequences. Theories on what causes drug addiction include traumatic life experiences, genetics, and adolescent or childhood use of substances. It is likely a combination of all these factors and others, which require further addiction medicine research.
