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?

An invalid test result is acceptable except in the following cases:

• The employer needs a negative test result (DOT and Consortium Pre-Employment, Return-to-Duty)
• The MRO has instructed a recollection and/or medical evaluation

Return-to-Duty and SAP referrals are relevant to non-negative results so, if an employee is restricted due to an invalid test result that employee should not be subject to an RTD program (unless the client’s corporate policy indicates otherwise).
