Addiction refers to compulsive drug use, while dependence refers to withdrawal symptoms when drug use is stopped.
Step 2: Tolerance concept.
Repeated drug use increases receptor tolerance, requiring higher doses for the same effect.
Step 3: Evaluating dependence.
Dependence causes physical and psychological distress, not social compliance.
Step 4: Evaluating option (3).

Step 5: Checking other options.
Other statements correctly describe addiction and physiological changes.
Step 6: Final conclusion.
Thus, option (3) is incorrect.
