The nation’s decades-long campaign to combat drunk driving continues to make our roads safer, but use of marijuana and prescription drugs is increasingly prominent on the highways, creating new safety questions, according to two studies released by the Department of Transportation’s National Highway Traffic Safety Administration.
One study, the latest version of NHTSA’s Roadside Survey of Alcohol and Drug Use by Drivers, found that the number of drivers with alcohol in their system has declined by nearly one-third since 2007, and by more than three-quarters since 1973.
But the same survey found a large increase in the number of drivers using marijuana or other illegal drugs. In the 2014 survey, nearly one in four drivers tested positive for at least one drug that could affect safety.
A one-third reduction in alcohol use over just seven years “shows how a focused effort and cooperation among the federal government, states and communities, law enforcement, safety advocates and industry can make an enormous difference,” said NHTSA Administrator Mark Rosekind.
However, Rosekind said, the survey raises “significant questions about drug use and highway safety. The rising prevalence of marijuana and other drugs is a challenge to everyone who is dedicated to saving lives and reducing crashes,” said NHTSA Administr
The reports are consistent with another study released in June by Public Health Reports. This study found that since 1993, the profile of a drugged driver has changed substantially. More drivers are now testing positive for prescription drugs, cannabis, and multiple drugs, and they are more likely to be older than 50.
“While we’ve seen a decrease over the years in motor vehicle fatalities involving people under the influence, the nature of those crashes is changing,” said the Public Health Reports study author, Fernando Wilson, PhD, associate professor at the University of Nebraska Medical Center.
Wilson found that the percentage of drugged drivers with three or more drugs in their system nearly doubled from 1993 to 2010, increasing from 11.5 percent to 21.5 percent.
