Researchers from the Columbia University Mailman School of Public Health looked at more than 14,000 drivers who were at fault in accidents, and the same number of drivers who were not at fault for the crash. They found that 28 percent of at-fault motorists tested positive for alcohol, 10 percent tested positive for marijuana, and four percent had both in their systems.
