Question 5011

Does drug use improve reaction time in any case?

  1. Yes, with cocaine.
  2. Yes, in some cases by shortening it.
  3. No, not in any case.
Show answer and explanation

Correct answer: No, not in any case.

No. No drug improves reaction time. Depressants, such as heroin or tranquilizers, increase it, and cannabis also makes you react more slowly. Cocaine makes you feel quick, but you respond impulsively and make more mistakes.
