Every time I've ever taken a drug test the form has always asked what medications I'm taking, in the distant past I had also even been asked to bring the medication in with me for the test, however the place I get randomly tested at for my work never asks to physically see the medication, but it does have a spot to list what medications I am using and what condition I take them for.

Do you know if it is often that they would check for other compounds that would come from Marijuana and not Marinol, such as CBD and CBN levels? By the way, this is for DOT drug testing in case that would make a difference.
