Which term describes the use of habit-forming drugs or substances which impair behavior?

• A. Addiction
• B. Substance dependence
• C. Substance misuse
• D. Substance abuse

Answer: (D)

The idea being tested is impairment from using certain drugs or substances. Substance abuse best matches this, as it specifically describes using habit-forming substances in a way that harms functioning or safety—leaving someone unable to perform tasks effectively, drive safely, or meet responsibilities. Addiction focuses on a chronic pattern of compulsive use and cravings, which is a deeper, ongoing condition rather than simply impaired behavior. Substance dependence centers on the body’s adaptation to a substance, such as tolerance and withdrawal. Substance misuse can overlap with abusive use but is more about using inappropriately or not as prescribed, and may not always imply impairment.
