What is 'Tolerance' in relation to alcohol consumption?

Tolerance in relation to alcohol consumption refers to the body's adaptation to large doses of alcohol. This means that over time, as a person consumes alcohol regularly or in greater quantities, their body becomes accustomed to its presence. As a result, the individual may need to consume more alcohol to achieve the same effects that they once experienced with smaller amounts. This adaptation occurs through various physiological changes, including alterations in the metabolism of alcohol and changes in the brain's response to alcohol.

When tolerance develops, individuals may not feel the effects of alcohol as strongly as they did when they first started drinking, leading to increased consumption and potential dependence on alcohol. This concept is crucial in understanding patterns of alcohol use and the risks associated with excessive drinking.
