The term "alcoholic" refers to a person who has an addiction or dependency on alcohol. This can manifest in various ways, including excessive consumption, loss of control over drinking habits, physical withdrawal symptoms when not consuming alcohol, and continued use despite negative consequences such as health problems, relationship issues, or legal troubles. An alcoholic may experience cravings for alcohol, struggle with impulse control, and have difficulty stopping their consumption even if they want to. The term is also used more broadly to describe any substance that contains ethanol, a psychoactive chemical compound found in alcoholic beverages.
