Final answer:
Voluntary intoxication is the type of intoxication that cannot be used as a defense in a legal context because it involves a person knowingly impairing their own judgment by consuming alcohol.
Step-by-step explanation:
The kind of intoxication that can never be used as a defense in legal terms is voluntary intoxication. This is because individuals are expected to be aware of the potential effects of alcohol consumption. When a person voluntarily consumes alcohol to the point of intoxication and commits a crime, they are still held accountable for their actions. Voluntary intoxication does not excuse criminal conduct because it is a conscious choice to impair one's own faculties. Acute alcohol intoxication can lead to dangerous situations such as seizures, aspiration pneumonia, and injuries, and it is associated with alcohol-related crimes, where perpetrators are often more intoxicated than their victims. According to U.S. law, specifically the Eighteenth Amendment, it's also illegal to transport or import intoxicating liquors in violation of state laws.
