Marijuana use has a very different effect on school performance than alcohol does.

• A. False
• B. True
• C. Depends on the student
• D. Cannot be determined

Answer: (A)

Understanding how substances affect school performance means recognizing that both marijuana and alcohol can undermine academic success, even though they do so in different ways. Alcohol tends to cause clear, immediate impairment when drinking, including reduced attention, slower processing, and hangovers that can lead to missed classes or poor test results. Marijuana can affect focus, memory, and motivation, with the effects varying based on potency, how often someone uses it, and their individual tolerance. Because both substances can lead to lower grades, reduced participation, and poorer school performance, the claim that they have very different effects isn’t universally true. Individual factors matter, but the general pattern is that either substance can harm academic outcomes, so the statement is not supported.
