Addiction is a complex condition characterized by the compulsive use of substances or engagement in behaviors despite harmful consequences. It often involves a psychological or physical dependence on a particular substance, such as drugs or alcohol, or an activity, such as gambling or gaming. Individuals with addiction may experience intense cravings, loss of control over their actions, and continued involvement in the addictive behavior despite negative impacts on their health, relationships, and daily functioning. The development of addiction can be influenced by a combination of genetic, environmental, and psychological factors. Treatment typically involves a combination of therapy, support groups, and sometimes medication to help manage withdrawal symptoms and reduce the risk of relapse.
