Over 40% of US drivers who use both alcohol and marijuana admitted they drive under the influence of one or both of the substances, according to a recent study. However, nearly half of those surveyed said they did not get behind the wheel while intoxicated.
Still, some cannabis consumers claim that driving while high does not affect their ability to operate an automobile despite warnings from law enforcement that the number of fatal car crashes involving cannabis has more than doubled in the past several years.
