How does marijuana affect driving abilities?

Marijuana has been shown to impair sensory and perceptual skills, which directly affects a driver's judgment. When someone uses marijuana, the psychoactive component, THC, can alter cognitive functions, including attention, reaction time, and the ability to process information. This impairment can lead to difficulties in effectively recognizing and responding to traffic signals and potential hazards, which are crucial for safe driving.

The reduction in judgment capability makes it harder to make quick and accurate decisions on the road, increasing the likelihood of accidents. This is particularly concerning in dynamic driving situations that require rapid responses. Studies show that marijuana use can result in slower reaction times and decreased coordination, both of which are vital for safe driving.

In contrast to enhancing abilities or having no impact, the evidence strongly supports that marijuana adversely influences driving performance, making it critical for drivers to understand these risks.
