Which of the following is NOT a cognitive effect associated with cannabis use in teens?

• A. Impaired memory and learning
• B. Reduced attention and concentration
• C. Slower reaction times
• D. Increased motivation

Answer: (D)

Cannabis can affect how the brain processes information, especially in teens whose brains are still developing. THC disrupts memory formation and recall, so learning and remembering new information can be impaired. It also hits attention and concentration, making it harder to stay focused on tasks, and slows processing and responses, leading to slower reaction times.

The statement about increased motivation isn’t describing a cognitive impairment. Cognitive effects refer to memory, attention, and thinking speed, not to motivational states. So, increased motivation doesn’t fit with the cognitive changes typically seen with cannabis use in teens.
