What primary effect does marijuana have on cognition and motor skills?

• A. Enhanced focus
• B. Impaired judgment and decreased coordination
• C. Increased energy
• D. Improved memory

Answer: (B)

Marijuana primarily affects cognition and motor skills by impairing judgment and decreasing coordination. The active compounds in marijuana, particularly tetrahydrocannabinol (THC), interact with the brain's cannabinoid receptors, which can lead to alterations in perception, attention, and decision-making processes. This impairment can manifest as difficulties in thinking clearly, solving problems, and processing information, which are essential for sound judgment.

Additionally, marijuana affects motor skills by hindering coordination and reaction times. This can make activities such as driving or operating machinery particularly dangerous. Users may experience a lack of motor control, resulting in clumsiness and slowed reflexes, which underscores the risks associated with the drug.

Understanding these effects is crucial, especially in clinical settings or situations where individuals may be under the influence. While some may perceive enhanced focus or increased energy, the overall evidence points to cognitive deficits and motor impairment as primary effects of marijuana use.
