What is alcohol?

Esta entrada también está disponible en: Spanish

Alcohol is a drug.

It is classed as a depressant, meaning that it slows down vital functions—resulting in slurred speech, unsteady movement, disturbed perceptions and an inability to react quickly.

As for how it affects the mind, it is best understood as a drug that reduces a person’s ability to think rationally and distorts his or her judgment.

Although classified as a depressant, the amount of alcohol consumed determines the type of effect. Most people drink for the stimulant effect, such as a beer or glass of wine taken to “loosen up.” But if a person consumes more than the body can handle, they then experience alcohol’s depressant effect. They start to feel “stupid” or lose coordination and control.

Alcohol overdose causes even more severe depressant effects (inability to feel pain, toxicity where the body vomits the poison, and finally unconsciousness or, worse, coma or death from severe toxic overdose). These reactions depend on how much is consumed and how quickly.

There are different kinds of alcohol. Ethyl alcohol (ethanol), the only alcohol used in beverages, is produced by the fermentation of grains and fruits. Fermenting is a chemical process whereby yeast acts upon certain ingredients in the food, creating alcohol.
