it does not make sense to me that an employer would prescreen with 20 ng when the field does not involve transportation or mental health or prescription drugs

it would seem they would get a lot moer initital positives and have to pay for the gc/ms and so would want to set it at 50

at least this is what i am telling myself to try to calm down
