“Currently, one of nine drivers involved in fatal crashes would test positive for marijuana,” Dr. Guohua Li, director of the Center for Injury Epidemiology and Prevention at Columbia, and co-author of the study told HealthDay News.

Researchers from Columbia University’s Mailman School of Public Health gathered data from six states – California, Hawaii, Illinois, New Hampshire, Rhode Island, and West Virginia – that perform toxicology tests on drivers involved in fatal car accidents. This data included over 23,500 drivers that died within one hour of a crash between 1999 and 2010.

Li reported in the study that alcohol contributed to about 40 percent of traffic fatalities throughout the decade.

The researchers found that drugs played an increasing role in fatal traffic accidents. Drugged driving accounted for more than 28 percent of traffic deaths in 2010, which is 16 percent more than it was in 1999.
The researchers also found that marijuana was the main drug involved in the increase. It contributed to 12 percent of fatal crashes, compared to only 4 percent in 1999.
