What does the study of cocaine suggest about aggression?

• A. It always leads to social aggression.
• B. It is unrelated to biological influences.
• C. It can lead to aggressive behavior, considered a personal choice.
• D. It shows that genetics determine aggression levels.

Answer: (C)

The study of cocaine suggests that it can lead to aggressive behavior, which is considered a personal choice because it highlights the interplay between substance use and individual decision-making processes. Research indicates that cocaine can affect the brain's reward systems, altering mood and behavior and potentially leading to heightened aggression in some individuals. This relationship implies that while the drug may influence aggressive tendencies, the ultimate expression of aggression is influenced by personal choices and other contextual factors. Additionally, this perspective accounts for the variability among individuals in how they respond to cocaine, reinforcing the idea that personal agency plays a significant role in behavioral outcomes.
