Most recent Drug & Alcohol Testing Questions

On a hair test and oral fluid panel/test certificates, does CBD fall under cannabinoids?

YES – Currently, CBD is not listed as an independent substance on any testing panel. DISA drug test (urine, hair, saliva) will screen for THC or cannabinoids.

It is said that you would have to take CBD in 1000-2000mg doses for it to show up on a test and the fact that THC products are not regulated, and the dosing could be off. Is that true for everyone, or do some clients get to decide their threshold?

There is no test for CBD, DISA’s tests will screen for THC or cannabinoids. Any test that screens for THC or cannabinoids is going to report findings for THC or cannabinoids that exceed the panel thresholds (levels). The origin of the substance will not be considered by the Medical Review Officer (MRO). DISA’s non-DOT corporate policy offers clients the option to customize testing panels.

Do different testing policies for different clients have different saturation levels as a threshold for positive vs. negative tests?

YES - All drug testing policies have a testing “panel.” Testing panels consist of substances and level thresholds (limit of detection). DISA offers policies with customized panels, in addition to policies that require standard/regulated panels. (Please note, all DOT and some safety-sensitive, non-DOT drug testing programs have mandatory testing panels)

Can an employee test positive for marijuana from second hand smoke?

Cut-off levels have been established to rule out passive or second hand smoke inhalation.  Clinical studies have been conducted to establish the cut-offs, and the studies concluded that it is extremely unlikely for an individual to test positive due to passive or second hand smoke inhalation.

If an employee informs the employer that they are using a CBD product, what is the employers responsibility if that employee is in a safety-sensitive position?

The employer’s responsibility is to explain that there is no exception (under DOT regulations) for the use of any product that presents as THC metabolites and exceeds set thresholds on a DOT drug screen. If it is non-DOT, they should refer to the company policy. If the policy accepts CBD oil, then that should be communicated.
