Heavy amphetamine use negatively impacts a driver’s coordination. While amphetamines may create a temporary sense of increased energy and alertness, the reality is that their use can lead to significant impairment in motor skills and decision-making abilities. Substance use, particularly heavy use, often disrupts the normal functioning of the nervous system, which is crucial for executing precise physical movements such as steering, braking, and navigating through traffic. This deterioration in coordination can compromise a driver's ability to react appropriately to changing road conditions or unexpected events, ultimately elevating the risk of accidents.
In contrast, the notion that amphetamines might enhance reaction time or improve coordination fails to recognize these adverse effects, and suggesting that they have no effect on driving ability overlooks the substantial risks associated with their use.
