What is an intoxicant?

An intoxicant is defined as a substance that causes intoxication, which means it alters a person’s mental or physical state, often resulting in impaired judgment, altered perceptions, or altered behavior. This includes various types of substances, such as alcohol, drugs, and certain chemicals, which can lead to effects such as euphoria, sedation, or disorientation.

The focus is on the term "intoxication," which specifically relates to the impairment caused by these substances. An intoxicant is not merely something that increases alertness, enhances mood, or decreases physical coordination; rather, it is directly linked to the broader effect of inebriation or poisoning that leads to a state where normal functioning is significantly compromised. Hence, the correct selection accurately captures the essence of what an intoxicant does.
