The American Trucking Association released a statement in October 2021, citing retiring driving veterans and lower wages as the partial cause for the shortage of more than 80,000 drivers. However, another cause for this shortage is being attributed to adult-use legalization and drivers testing positive for cannabis.
A March 2022 U.S. Department of Transportation summary report states that as of April 1, 2022, 10,276 commercial truck drivers tested positive for THC. (Although this is a significant decrease in numbers, compared to 31,085 violations in 2021 and 29,511 violations in 2020.) Cannabis leads the data as the highest positive drug tests for drivers, but this also includes data about drivers who test positive for cocaine, methamphetamine, oxymorphone and more.
The situation is especially difficult for drivers who consume because many of them travel through multiple states with varying approaches to legalization.
According to an article on Stacker, the Department of Transportation (DOT) Handbook: A Compliance for Guide Truck Drivers confirms that cannabis is still federally illegal. “While states may allow medical use of marijuana, federal laws and policy do not recognize any legitimate medical use of marijuana. Even if a state allows the use of marijuana, DOT regulations treat its use as the same as the use of any other illicit drug.”
