Can Drivers Use Recreational Marijuana?

Many states are now passing laws that make recreational marijuana use legal. This change has many truck drivers and those training for their CDL’s wondering if they can occasionally use marijuana. The answer is a resounding no. In fact, recreational marijuana use causes big problems for drivers, even if they are not using it while driving. Marijuana and CBD products that contain THC can linger in the bloodstream for months, and result in a positive drug test.

What is the DOT’s Stance on Recreational Marijuana Use?

The DOT is very firm on where it stands on marijuana. They maintain a long-standing drug testing program that adheres to federal regulations prohibiting recreational marijuana use. Therefore, if a driver fails a DOT-mandated drug test and states they used recreational marijuana they will still fail the test. Medical Review Officers have been strictly told that recreational marijuana is not a reason to verify a drug test as negative even if the marijuana was consumed in a state where it is legal. Additionally, medical marijuana use is not permitted and will result in a failed test.

What Happens If You Fail an Alcohol or Drug DOT-Mandated Safety Test?

If you consume marijuana or any other drug and fail an alcohol or drug DOT-mandated safety test you will immediately be removed from your duties. Next, you must connect with a SAP (Substance Abuse Professional) and begin the return-to-duty process.
