What is the most common type of alcohol found in an intoxicated person's body?

The most common type of alcohol found in an intoxicated person's body is ethyl alcohol, also known as ethanol. Ethanol is the active ingredient in alcoholic beverages such as beer, wine, and spirits, which are commonly consumed and can lead to intoxication.

When people consume alcoholic drinks, it is ethanol that is absorbed into the bloodstream and affects the central nervous system, leading to the various physical and cognitive impairments associated with intoxication. In contrast, methyl alcohol (methanol) and isopropyl alcohol (isopropanol) are toxic and not typically present in alcoholic beverages consumed by the general public. While butyl alcohol is used in various industrial applications and some household products, it is not found in common alcoholic drinks.

Therefore, ethyl alcohol is the primary substance responsible for intoxication and is significantly more prevalent in cases of alcohol consumption compared to the other listed types of alcohol.
