What effect does cannabis have on driving ability?

Cannabis is known to have a significant impact on driving ability, primarily because it can slow reaction time and impair coordination. When a person consumes cannabis, compounds such as THC (tetrahydrocannabinol) interact with the brain, affecting areas responsible for judgment, motor coordination, and attention. This impairment can result in slower reflexes, reduced ability to track moving objects, and difficulty in processing information quickly, all of which are critical for safe driving.

In contrast, other options suggest improvements to driving ability or no effects at all, which do not align with the established research on cannabis and its effects on cognitive and motor functions. This is why understanding the negative impact of cannabis on driving is vital for promoting road safety and responsible behavior behind the wheel.
