Ethanol is classified as which of the following?

Ethanol is classified as a food, drug, and poison due to its multifaceted effects on the human body and its various roles in different contexts.

As a food, ethanol provides calories and can be metabolized for energy. It is often consumed in beverages, which are a part of social and cultural practices worldwide.

In terms of its classification as a drug, ethanol functions as a psychoactive substance that affects the central nervous system. It can alter mood, perception, and behavior, which is why it is often used recreationally.

Furthermore, ethanol is classified as a poison because, in excessive amounts, it can be toxic and lead to serious health issues, including alcohol poisoning, organ damage, and death. This toxic nature is especially evident at high blood alcohol concentrations, where it can impair bodily functions and lead to dangerous situations.

Considering these three roles, ethanol clearly fits into all three categories, leading to the conclusion that it is classified as a food, drug, and poison.
