A group of high school students who have smoked marijuana ignore "no trespassing" signs and climb over a fence into a construction site and walk through an unfinished building. In this situation, the use of marijuana may have contributed to the students' willingness to engage in this risky behavior because marijuana:

• A. causes visual and aural distortions in the peripheral nervous system.
• B. affects receptors in the brain involved with judgment, thinking, and problem solving.
• C. alters kinesthetic perceptions of how and where the body is moving in space.
• D. significantly inhibits the nervous system's fight or flight response.

Answer: (B)

The main idea being tested is how marijuana impairs higher-order thinking, especially judgment, decision-making, and problem solving, which can lead to risky behavior. THC affects receptors in brain areas that regulate thinking and planning, particularly regions involved in evaluating consequences, weighing options, and solving problems. When these cognitive functions are slowed or distorted, a person may not accurately assess the risks of entering a construction site or ignoring safety signs, making reckless choices more likely. This is why the option describing effects on judgment, thinking, and problem solving is the best fit. While marijuana can slightly alter perception or coordination, the most direct link to deciding to engage in risky activity is the impairment of executive functions that govern how we make decisions. The other choices describe sensations or responses that are less central to the decision to trespass in this scenario.
