Which statement correctly differentiates tolerance from withdrawal?

Which statement correctly differentiates tolerance from withdrawal?

• A. Tolerance involves needing more to achieve the same effect; withdrawal involves physiological and psychological symptoms when reducing use.
• B. Tolerance and withdrawal are synonyms.
• C. Withdrawal precedes tolerance.
• D. Tolerance only occurs with caffeine.

Answer: (A)

The test is about how the body adapts to repeated drug use. Tolerance means you need more of the substance to achieve the same effect because the body becomes less responsive to it over time. Withdrawal refers to the physiological and psychological symptoms that appear when you reduce or stop using the drug after dependence has developed. The statement that correctly differentiates them says you need more to get the same effect (tolerance) and you experience symptoms when you cut back or quit (withdrawal). Tolerance and withdrawal are not synonyms, and tolerance is not limited to caffeine; many substances can produce both tolerance and withdrawal. They also don’t occur in a fixed order where withdrawal comes first.
