Intoxication is defined as:

• A. Altered state of mind due to the consumption of substances that cause cognitive impairment
• B. A temporary state of heightened physical fitness
• C. A chronic condition unrelated to substance use
• D. A legal term for intoxicated driving

Answer: (A)

Intoxication is an altered state of mind that occurs after consuming substances that impair cognitive function. This captures the idea that intoxication involves impairment of thinking, judgment, memory, and coordination caused by substances. The other descriptions don’t fit: one suggests a temporary boost in physical fitness, another describes a chronic condition unrelated to substances, and the last is a legal phrase tied to driving under the influence rather than the impairment itself. In practice, recognizing intoxication involves noticing changes in alertness, decision-making, and motor control due to substance use.
