Craving for the substance is a feature of both physical and psychological dependence.

• A. A craving for the substance.
• B. A fixed minimum legal age requirement.
• C. An inability to experience pleasure from other activities.
• D. A need to seek lifelong drug-free abstinence.

Answer: (A)

Craving for the substance reflects the strong motivational drive that underpins dependence. In physical dependence, the body adapts to repeated use, and when the substance isn’t available, withdrawal can intensify the desire to use to relieve discomfort. In psychological dependence, craving is a powerful, emotionally charged urge to obtain the drug, often triggered by cues and reinforced by the brain’s reward systems. Both forms center on the compelling urge to use, which is why craving is the defining feature. The option about a fixed minimum legal age is unrelated to how dependence manifests. An inability to experience pleasure from other activities describes anhedonia, which can occur with some addictions but isn’t the defining trait of dependence. The idea of lifelong drug-free abstinence isn’t a requirement of dependence either, since relapse and continued use can occur despite dependence.
