In addiction neuroscience, negative reinforcement is defined as drug use that is driven by

• A. The pursuit of positive pleasurable effects
• B. The avoidance of withdrawal symptoms or negative states
• C. The enhancement of social status
• D. The creation of tolerance

Answer: (B)

Negative reinforcement in addiction means drug use is driven by removing an aversive state, not by chasing pleasure. The correct idea is that individuals use a substance to avoid withdrawal symptoms or negative emotional/physical states, so the relief provided by the drug reinforces continuing use. For example, when someone experiences withdrawal—anxiety, dysphoria, physical discomfort—taking the drug alleviates those feelings, making the behavior more likely to recur. This differs from seeking positive pleasurable effects, which would be positive reinforcement—driven by the pursuit of reward and euphoria. The other options don’t capture the reinforcement mechanism: chasing social status isn’t about relief from aversive states, and tolerance is a pharmacological adaptation, not a driver of the reinforced behavior itself.
