A state where the body adapts to a drug, leading to withdrawal symptoms when the drug is not taken is known as what?

• A. Physical dependence
• B. Paradoxical drug effect
• C. Outpatient treatment
• D. Oxford houses

Answer: (A)

The main idea here is that the body changes its normal functioning in response to a drug, so when the drug isn’t taken, withdrawal symptoms appear. This physiological adaptation is called physical dependence. It happens because the body adjusts to the drug’s presence, which can also lead to tolerance—needing more of the drug to achieve the same effect—and, if the drug is stopped, withdrawal symptoms emerge as the body readjusts. This concept is distinct from addiction, which involves compulsive use and other behavioral factors; the term here specifically describes the bodily change and the withdrawal that follows cessation.

The other options don’t fit because they describe different things: a paradoxical drug effect would be an opposite or unexpected reaction to a drug; outpatient treatment and Oxford houses are settings or programs for treatment, not states of the body reacting to drug exposure.
