Columbia Finds Fatal Car Crashes Increase for Drivers Who Test Positive for Both Alcohol and Drugs

Drugged driving has been a safety issue of increasing public concern in the United States and many other countries but its role in motor vehicle crashes has not been adequately examined. In a new study conducted at the Columbia University Mailman School of Public Health, researchers assessed the association of driver drug use, as well as the combination of drugs and alcohol, with the risk of fatal crash. They found that drug use is associated with a significantly increased risk of fatal crash involvement, particularly when used in combination with alcohol. The study provides critical data for understanding the joint effect of alcohol and drugs on driving safety.
