Question

which effect is most closely linked to cocaine use?
○ increased drowsiness while driving
○ decreased coordination while driving
○ decreased reaction rate while driving
○ increased aggressiveness while driving

Explanation:

Cocaine is a stimulant drug. Stimulants can increase aggression, irritability, and impulsivity. Increased drowsiness (first option) is more linked to depressants or sedatives. Decreased coordination and decreased reaction rate (second and third options) are also not typical primary effects of cocaine; cocaine often increases alertness (though with impaired judgment and increased risk - taking). Increased aggressiveness is a known behavioral effect of cocaine use, especially in the context of driving where impaired judgment and increased impulsivity can lead to aggressive driving behaviors.

Answer:

D. increased aggressiveness while driving
