In drug abuse, addiction is best defined as:
AA purely physical dependence on a drug
BA psychological attachment to the effects of the drug (euphoria, well-being), driving the user to seek it even when not needed
CA withdrawal syndrome
DAn allergic reaction to the drug
Answer & Solution
Correct answer: B. A psychological attachment to the effects of the drug (euphoria, well-being), driving the user to seek it even when not needed
**Addiction = psychological attachment** to the drug's perceived rewarding effects. Distinct from **dependence**, which is physical/physiological — withdrawal symptoms appear if regular dose is stopped (anxiety, shakiness, nausea, sweating).
