Cocaine use may be more prevalent that marijuana among truck drivers, according to the results of a University of Central Arkansas study reported in several trucking publications. The study linked the result to hair testing as opposed to urine tests.

“Our research found that DOT is seriously under reporting the actual use of harder drugs by truck drivers, such as cocaine and illegal opioids,” said Doug Voss, Ph.D., Professor of Logistics and Supply Chain Management at the University of Central Arkansas (UCA).
One reason for the under reporting of cocaine use by truck drivers is the methodology by which drivers are tested.
“Our analysis clearly concludes that hair testing identifies these harder drugs at higher percentages than the single urine testing method relied on by the federal government,” Doug Voss, Ph.D., Professor of Logistics and Supply Chain Management at the University of Central Arkansas (UCA), was quoted as saying.
