How do acute effects differ from chronic effects of drug use?

• A. Acute effects are immediate intoxication and impairment; chronic effects are long-term health problems and dependence.
• B. Acute effects are long-term; chronic effects are immediate.
• C. Acute effects include only withdrawal symptoms.
• D. Chronic effects can occur without any prior use.

Answer: (A)

The main point is how the timing of effects differs. Acute effects are the immediate effects that happen during and right after using a drug, such as intoxication and impairment of thinking, coordination, and reaction time. Chronic effects are the long-term consequences that develop with repeated or prolonged use, like ongoing health problems and the development of dependence.

So the correct idea is that acute effects are immediate intoxication and impairment, while chronic effects are long-term health problems and dependence. The other statements don’t fit: acute effects aren’t long-term, they aren’t limited to withdrawal symptoms, and chronic effects usually require prior use because they come from ongoing exposure.
