From CNN:
Driving under the influence of drugs was deadlier in 2015 than driving while drunk, a new report found. Still, some safety experts caution that drunken driving remains a bigger problem and say that drugged driving needs more research.
Positive drug tests were more common than the presence of alcohol among the fatally injured drivers who were tested in 2015, according to the report (PDF)released Wednesday by the Governors Highway Safety Association and the Foundation for Advancing Alcohol Responsibility, a nonprofit funded by alcohol distillers.
