What impact does marijuana use have on a driver's abilities?

Marijuana use adversely affects concentration, judgment, and perceptual skills, which are critical for safe driving. When a driver is under the influence of marijuana, cognitive functions that are essential for making quick decisions and assessing road conditions can be impaired. This can lead to slower reaction times and an inability to focus adequately on the task of driving, increasing the risk of accidents.

Research indicates that marijuana can alter an individual's ability to perceive time, distance, and speed, which are vital elements of safe driving. Furthermore, impairments in judgment can result in risky behaviors, such as driving too fast or failing to yield the right of way. Thus, understanding the negative impacts of marijuana on driving abilities is crucial for promoting road safety and making informed decisions about substance use before getting behind the wheel.
