What is the effect of marijuana on driving?

Answer: B — It can impair coordination and reaction times like alcohol

Marijuana significantly impairs coordination and reaction times, similar to the effects of alcohol. When consumed, marijuana can alter a person's cognitive function and motor skills, which are critical for safe driving. This impairment can lead to slower response times, difficulty in judging distances, and a lack of coordination, all of which can increase the risk of accidents. Therefore, the choice indicating that marijuana can impair coordination and reaction times accurately reflects the research and evidence supporting the dangerous effects of marijuana on driving abilities. The other options do not align with the scientific understanding of marijuana's impact on driving. For example, suggesting that it causes increased alertness and coordination underestimates the drug's impairing effects. A stance indicating that it has no impact on driving abilities is inconsistent with numerous studies demonstrating that marijuana can significantly compromise driving safety. Lastly, the idea that it only affects experienced drivers ignores the fact that marijuana affects all users, irrespective of their driving experience.
