Is there a difference in the DOT and Non DOT drug test?

Yes, there is a difference between DOT and Non-DOT drug tests. DOT drug tests are regulated by the Department of Transportation and typically include a specific panel of substances, including marijuana, cocaine, opiates, amphetamines, and phencyclidine (PCP). Non-DOT drug tests, on the other hand, can vary in the substances tested and are not subject to the same regulations, allowing employers more flexibility in their testing protocols. Additionally, DOT tests have stricter procedures and chain-of-custody requirements to ensure accuracy and compliance.
