Which term describes a condition that requires more of a drug to achieve the same effect?

• A. Tolerance
• B. Medicine
• C. Withdrawal
• D. Accident

Answer: (A)

This concept is tolerance: the body adapts to a drug with repeated use, so the same dose produces a weaker effect and a higher dose is needed to achieve the same response. It happens as the body becomes less responsive to the drug or as it becomes more efficient at clearing it from the system. Understanding tolerance helps explain why people may need increasing amounts of a medication or substance over time. The other terms don’t fit this idea—medicine is any drug used for treatment, withdrawal is the set of symptoms that occur when stopping a drug after dependence, and accident is unrelated to how a drug works in the body.
