Occurs when a user feels that a drug is necessary for normal functioning.

• A. Drug (chemical) dependence
• B. Psychological dependence
• C. Inherited risk factors
• D. Risk factors

Answer: (A)

This describes physical dependence: the body adapts to the drug and the user feels they must have it to function normally. Over time, this can lead to tolerance ( needing more to achieve the same effect) and withdrawal if the drug isn’t taken, which reinforces ongoing use to avoid those uncomfortable symptoms. Psychological dependence involves cravings or emotional attachment but doesn’t necessarily mean the body must have the drug to function day-to-day. Inherited or general risk factors refer to predispositions for using or developing problems, not the physiological need to use the drug to function.
