Multiple Choice

A physiological need for a drug with withdrawal symptoms when discontinued.

Explanation:
Physical dependence occurs when the body adapts to regular drug exposure and will experience withdrawal symptoms if the drug is stopped. This reflects a physiological need—the brain’s chemistry adjusts to the drug, so stopping disrupts function and produces withdrawal. It’s different from detoxification, which is the process of removing the drug from the body, and from substance-induced disorders, which are clinical syndromes caused by substance use. REM sleep has no relevance here.
