The statement Marijuana impairs short-term memory and concentration is true or false?

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

Answer: (B)

Marijuana use can impair cognitive performance, especially short-term memory and concentration. THC, the active compound, interacts with CB1 receptors in brain regions like the hippocampus and prefrontal cortex, which are important for forming new memories and maintaining attention. When under the influence, people often have trouble encoding new information, retaining it briefly, and staying focused on tasks, which is why memory and concentration seem disrupted. These effects are most noticeable during intoxication and tend to lessen as the drug’s effects wear off, though higher or repeated use can lead to longer-lasting changes for some individuals. Because of this dose- and time-dependent impairment, the statement that marijuana impairs short-term memory and concentration is true.
