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

DISA's services are segmented across several industries. The best way to reach the correct representative is using our contact us page.

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.

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.
