Alcohol is a central nervous system depressant, which does the opposite of a stimulant. Instead of increasing activity in the body, it slows it down. Drinking alcohol is actually a chemical called ethanol that works with a natural chemical in your brain called gamma-Aminobutyric acid (GABA). GABA is responsible for rest and relaxation helps facilitate sleep. Alcohol works by binding to GABA receptors to increase the chemical’s effectiveness. When you drink, alcohol increases GABA’s sedating and nervous system depressing effects. Like cocaine, alcohol also works to increase dopamine levels, which contributes to the euphoric intoxication you may experience while drinking. Alcohol’s effects may also contribute to its addictive potential. Consistent excessive drinking can lead to an alcohol use disorder, which can involve chemical dependence and addiction.
