A new study from the National Highway Traffic Safety Administration finds that drivers who use marijuana are at a significantly lower risk for a crash than drivers who use alcohol. And after adjusting for age, gender, race and alcohol use, drivers who tested positive for marijuana were no more likely to crash than who had not used any drugs or alcohol prior to driving. Nevertheless, there's plenty of evidence showing that marijuana use impairs key driving skills.
