Marijuana tops list of substances identified in CMV drivers’ failed drug tests: FMCSA

Washington — The first report to use data from the Federal Motor Carrier Safety Administration’s new Drug and Alcohol Clearinghouse shows that, from the database’s Sept. 28 launch through May, marijuana was the most common substance found in positive drug and alcohol tests among commercial motor vehicle drivers.

The national online database – aimed at enhancing road safety by providing, in real time, the names of CMV drivers who fail drug and alcohol tests – identified 10,388 positive tests for marijuana. Cocaine (3,192) and methamphetamine (2,184) were the next most common substances detected.

Under federal regulations, motor carriers must conduct pre-employment drug testing in addition to random testing. Employees who test positive are prohibited from performing safety-sensitive functions, which includes operating a CMV.

According to the report, 19,849 CMV drivers had at least one violation and were unable to operate until completing the return-to-duty process – including 15,682 drivers who had yet to begin the process.

In an article published June 15 in the Owner-Operator Independent Drivers Association’s Land Line magazine, Amber Schweer, supervisor of OOIDA’s drug and alcohol consortium, said the legalization of marijuana for medicinal and/or recreational use in numerous states may be complicating the problem.

“There is a huge misconception that just because it is legal on the state level that it will be OK on the federal level,” Schweer said. “That is not the case.”

CBD products also figured to factor into the findings, Schweer added. In a Feb. 18 policy and compliance notice, the Department of Transportation cautioned that CBD products may contain higher levels of THC – the main psychoactive ingredient in marijuana – than DOT allows in a controlled substance. DOT added that CBD use is not a “legitimate medical explanation” for a safety-sensitive employee who tests positive for marijuana.

“There are so many companies that claim you won’t test positive using their product when in reality they cannot guarantee that,” Schweer said. “Drivers are not heeding the warnings that are put out there and, unfortunately, are facing expensive and detrimental consequences to their career.”

Overall, the clearinghouse observed 21,156 positive tests for substance misuse among CMV drivers during the reporting period. Multiple substances can appear in positive tests, FMCSA notes in the report, which does not include the total number of tests conducted. Future reports are set to be released monthly. Employers made more than 905,000 queries into the clearinghouse since it was fully implemented Jan. 6.

DOT weighs in on CBD products: Workers in safety-sensitive jobs should be cautious

Washington — CBD products may have higher levels of tetrahydrocannabinol, or THC – the main psychoactive ingredient in marijuana – than the Department of Transportation allows in a non-controlled substance, the agency cautions in a Feb. 18 policy and compliance notice, adding that CBD use is not a “legitimate medical explanation” for a safety-sensitive employee who tests positive for marijuana.

The Agricultural Improvement Act of 2018 – also known as the Farm Bill – altered the definition of “marijuana” under the Controlled Substances Act of 1970. Hemp-derived products with a THC concentration of 0.3% or less are no longer considered controlled substances.

In response to inquiries about whether safety-sensitive employees (e.g., pilots, school bus drivers, truck drivers, transit vehicle operators, aircraft maintenance personnel, train engineers and ship captains) can use CBD products, DOT notes that although it requires testing for marijuana and not CBD, many CBD products have misleading labels.

“The products could contain higher levels of THC than what the product label states,” the notice states. “The Food and Drug Administration does not currently certify the levels of THC in CBD products, so there is no federal oversight to ensure that the labels are accurate.”

Employees who claim to use only CBD products can test positive for marijuana and run afoul of DOT’s drug-testing regulations.

“[Because] the use of CBD products could lead to a positive drug test result, [DOT]-regulated safety-sensitive employees should exercise caution when considering whether to use CBD products,” the notice states.
