Answer

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.

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.

How long does a failed drug test stay on DISA?

If an employee fails a drug test through DISA's program, it will remain on their account indefinitely. Depending on the industry and/or workplace policy, employees have the opportunity to complete a Return-to-Duty test and process. However, once a Return-to-Duty program is completed, the failed drug test will still remain on the individual's account indefinitely due to owners with zero tolerance.

Copies of test results may be obtained through several departments, depending on the results. For positive test results, please contact DISA’s Return-To-Duty department, or contact your MRO. For negative test results, please contact your company’s HR department.
