What is "alcohol"?

Alcohol is a psychoactive substance that is commonly consumed as a recreational drug and is also used in religious ceremonies and social gatherings. The most common types of alcohol that are consumed include beer, wine, and distilled spirits such as whiskey, vodka, and rum. Alcohol works as a depressant on the central nervous system, which can lead to a range of effects including relaxation, lowered inhibitions, impaired judgment, and slowed reaction time. While moderate alcohol consumption is generally considered safe for most adults, excessive drinking can lead to a range of health problems including liver damage, addiction, and increased risk of certain cancers.
