Which of the following is a sign of cocaine use?

• A. Dilated Pupils
• B. Sleepiness
• C. Constricted Pupils
• D. Decreased Talking

Answer: (A)

Cocaine use activates the body's fight-or-flight response, boosting sympathetic nervous system activity. This increases pupil size, producing dilated pupils (mydriasis), a common observable sign of stimulant intoxication. The heightened arousal from cocaine often accompanies increased energy and talkativeness, rather than sleepiness. Constricted pupils point to opioids or other depressants, not stimulants, and decreased talking is not typical of cocaine use, which tends to make people more vocal and energized.
