What defines opioid dependence?

• A. Physiological adaptation resulting in withdrawal symptoms upon abrupt discontinuation, usually after chronic use.
• B. Craving only with no withdrawal.
• C. It occurs after a single exposure.
• D. It is the same as tolerance.

Answer: (A)

Opioid dependence is a physiological state that develops with repeated opioid exposure, in which the body adapts so that stopping abruptly produces withdrawal symptoms. This withdrawal instability shows the body has become accustomed to the drug’s presence and now needs it to function normally. It’s something that typically arises after chronic use, reflecting physical adaptation of the nervous system and other tissues. This concept is distinct from tolerance, which is needing more of the drug to achieve the same effect, and from cravings or compulsive use without withdrawal symptoms, which would point to psychological dependence or addiction rather than true physiological dependence. It also cannot be established after a single exposure, since the body hasn’t yet undergone the adaptive changes required for withdrawal upon cessation.
