IS A PERSON’S DRIVING ABILITY AFFECTED BY MARIJUANA?
As the laws and law enforcement scramble to keep up with the rapidly changing laws on marijuana use, researchers are asking the question: How does marijuana affect driving ability? The answer to this question has important implications for the establishment of driving under the influence of marijuana thresholds such as those already in place for driving under the influence of alcohol.
As to be expected, law enforcement organizations with an anti-drug agenda, say that any amount of marijuana use significantly impairs driving ability but studies, perhaps with a less biased point of view, have not yet definitively answered the question. The primary psychoactive ingredient in marijuana, THC, affects a person’s coordination, sensory and time perceptions (according to the National Institute on Drug Abuse (NIDA)). These brain activities are important in driving so it would stand to reason that marijuana use would affect a person’s ability to drive safely.
